Product & Platform Announcements

  • Upcoming changes to Sponsored Messaging in the European Union (EU)

    Starting mid-October 2024, we will enable EU targeting for Sponsored Messaging campaigns including Message Ads & Conversation Ads, helping partners reach the target audience for their customer campaigns more effectively in the EU. Only EU members who agreed to receive Sponsored Messaging ads in their LinkedIn inbox, will be eligible to receive this ad type. Campaign setup, delivery, and reporting will function the same as all other Sponsored Messaging campaigns, now with the option to target within the EU. Read more.

    While serving to eligible EU members is enabled automatically by LinkedIn, please ensure to update any platform validations or tooltips and external articles on your end to reflect this change.

    We encourage you to plan for Sponsored Messaging EU targeting with a test-and-learn approach. Because EU members can choose/update how they’d like to receive ads in their inbox at any time, you may find differences in audience size when using Sponsored Messaging ads compared to other formats.

  • Creatives API : Creative Naming Support

    Starting with the 202410 version, you can add creative names to your ads using the new name field in the Creatives API. This field is supported across all creative formats. We recommend adopting this approach as we plan to deprecate the legacy options like InMailContents API or the AdDirectSponsoredContents API in the near future.

  • Ad Analytics API: Event Stage Reporting

    In order to enable more granular reporting for Event Ads, the Analytics and Statistics finders now support EVENT_STAGE as a new ad analytics pivot to get analytics data for Event Ads based on the Event stage.

  • Associate and Verify your App: LinkedIn Company Page

    Please ensure that your developer app is associated with a LinkedIn Company Page to have access to the necessary features and functionality of LinkedIn Marketing API products. The organization that owns the Page you select will function as the publisher of the app. If you don’t have a Page, you have the option to create a Page. As a developer, you must send an app verification request to your organization’s Page super admin, who is responsible for approving or denying the request to associate an app with a LinkedIn Page. Read more.

  • AdAccounts, Campaign Groups, Campaigns, Creative API: Adopt Cursor-based Pagination

    Starting with the January 2024 version (202401) we moved from index-based to cursor-based pagination for better scalability of our platform. To properly paginate you will need to use the pageSize and pageToken query parameters.

September 2024 - Version 202409

Product & Platform Announcements

  • Connected TV (CTV) Campaigns: Brand Safety Capabilities

    Last month, we shared that our partners can now use the new boolean field connectedTelevisionOnly in Campaign API and Ad Supply Forecasts API to create and run Connected TV (CTV) video ad campaigns. LinkedIn Connected TV (CTV) ads help your customers reach their audience on a large-screen experience, using first-party data from our community of one billion professionals.

    Starting with the 202409 version, we are extending the brand safety capabilities for CTV via Publisher Lists. We have introduced a new field publisherListType in the request body schema for POST /globalPublisherList to specify CONNECTED_TELEVISION as a separate category from WEB_AND_APP for the type of publisher list to be downloaded. This enables your customers to download the list of Connected TV apps directly in your UI and access information such as Bundle ID, Publisher Name, Platform URL (when available), and IAB Categories.

    Please note, this new capability is available in addition to the following features for LAN that are available for CTV by default. Read more about the definitions and different use cases of these lists here.

    • Creating and uploading a blocklist or allowlist
    • Applying a blocklist or allowlist
    • Applying IAB categories

  • Media Planning API: Forecast CTV Campaign Delivery

    Partners now have access to a new capability in LinkedIn’s Media Planning API to forecast CTV-only campaign delivery. You can add an optional ctvOnly field in the API request to forecast CTV-only campaigns in your media plans.

  • Conversions API: Auto-campaign Association:

    A new field autoAssociateCampaigns has been added to the request query parameters for POST /conversions. This field enables automatic association of all ACTIVE, PAUSED, and DRAFT campaigns with a conversion rule, ensuring only these associated campaigns are considered for reporting and optimization.

Product & Platform Announcements

  • Campaign API and Ad Supply Forecasts API: Connected TV (CTV) Only Campaigns
    We are excited to share that starting with the 202408 version, we have introduced a new boolean field connectedTelevisionOnly in the Campaign API and Ad Supply Forecasts. This new field enables the creation and delivery of Connected TV (CTV) video ad campaigns. LinkedIn Connected TV (CTV) ads help your customers reach their audience on a large-screen experience using first-party data from our community of one billion professionals. CTV campaign metrics are identical to existing video campaign metrics.

    Please note the requirements below and check out our recommendations to make the most out of LinkedIn CTV campaigns here.

    • Ad Format: Video only
    • LinkedIn Placement: LAN (LinkedIn Audience Network)
    • Campaign Objective: Brand Awareness
    • Geo Eligibility: US & Canada
    • Language: English only

  • Campaign API: Frequency Cap Customization
    You can now use a new field optimizationPreference in the Campaign API to set a maximum campaign-level frequency to better manage reach and frequency outcomes. Frequency is defined as the number of times an ad is served to a LinkedIn member over a specific time period. Research has shown that frequency is a key factor in improving brand awareness from advertising campaigns and positively influences ad recall and purchase intent.

    With this new frequency control, you can set a maximum frequency value between 3 to 30 within a 7-day window. This capability is available for CTV campaigns with the brand awareness objective and is accessible via a limited beta for LinkedIn Feed and LAN (LinkedIn Audience Network) campaigns.

  • Conversions API: Deprecating MQL and SQL Conversion Types
    Starting with the 202408 version, we will no longer support MARKETING_QUALIFIED_LEAD and SALES_QUALIFIED_LEAD conversion types when creating a new conversion rule. We recommend using QUALIFIED_LEAD as the conversion type, which has been available since version 202405.

  • AdAnalytics API: Reporting Changes to In-Feed Video & Sponsored Messaging
    Starting in July, we enhanced our measurement methodology for Video and Sponsored Messaging campaigns on LinkedIn.com and the LinkedIn mobile app to align more closely with industry standards. As a result, you may observe changes in your overall campaign reports.

  • Video Campaigns Video ads that serve on LinkedIn.com and in the LinkedIn mobile app now report impressions and clicks only when they start to play. This may lead to a decrease in Video ad impressions, clicks, and CTRs reported for your customer campaigns, and CPMs, CPCs, and Video View Rates may increase. These changes apply to videos that run on LinkedIn feed only; campaigns utilizing LAN/CTV are not impacted.

  • Sponsored Messaging Impressions, clicks, and related metrics (such as CPM and CPC) from Sponsored Messaging campaigns are no longer reported. However, historical data from your customer campaigns delivered before late July is not impacted. You can continue to review sends and opens metrics under the “sends” and “opens” columns, respectively. We recommend that you utilize sends and opens metrics moving forward versus the historical data for impressions, clicks, and derived metrics.

July 2024 - Version 202407

Product & Platform Announcements

  • AdAnalytics API: Reporting changes to In-Feed Video & Sponsored Messaging
    At LinkedIn, we are committed to delivering measurement solutions that meet or exceed industry standards. We are pleased to share that we have improved our measurement methodology for Video and Sponsored Messaging campaigns that serve on LinkedIn.com and in the LinkedIn mobile app to better align with the industry standards. Due to these changes you may see a change in your holistic campaign reports.

  • Video Campaigns
    Beginning July 11, Video ads that serve on LinkedIn.com and in the LinkedIn mobile app will begin reporting impressions and clicks only when they begin to play. This may result in a decrease of Video ad impressions, clicks, and CTRs reported for your customer campaigns, and CPMs, CPCs and Video View Rates may increase. These changes apply to videos that run on LinkedIn feed only, campaigns utilizing LAN/CTV will not be impacted.

  • Sponsored Messaging
    Starting July 30, impressions, clicks, and related metrics (such as CPM and CPC) for Sponsored Messaging campaigns will no longer be reported. Historical data from campaigns prior to late July 2024 will remain unaffected. You can still access sends and opens metrics under the "sends" and "opens" columns, respectively. We recommend using sends and opens metrics for future analysis instead of relying on historical data for impressions, clicks, and derived metrics.

  • AdAnalytics API: New metrics available for Sponsored Newsletter Articles
    We are introducing two new metrics to the API: subscriptionClicks and viralSubscriptionClicks. The subscriptionClicks metric measures the number of members whose first click on the ad in the feed is the Subscribe button. Any clicks on +Subscribe on subsequent pages, for example, the newsletter article page or the newsletter landing page, aren’t counted as part of this metric. The viralSubscriptionClicks metric measures the number of members whose first click on the post is the Subscribe button that resulted from other members sharing a sponsored newsletter article with their network.

  • Matched Audiences API and Conversions API: Email hashing guideline
    To ensure the best audience match rates the following guidelines must be followed for email hashing:

    • Convert all the email addresses to lowercase before hashing
    • Remove any whitespace in the email address and then generate appropriate hash

  • Leadgen Forms: Ability to apply custom Images
    We have introduced an enhancement to Leadgen Forms that allows advertisers to personalize their Leadgen Form backgrounds with custom images (for sponsored content only), instead of the form automatically defaulting to the ad image. However, please note that at the time of the initial rollout, partners or advertisers will not be able to edit custom images via API. If you would like to explore or leverage this new feature, we recommend utilizing LinkedIn Campaign Manager to create and edit your Leadgen Forms and offer a more tailored experience for your target audience.

  • AdCampaignGroups API: Objective Type for Campaign Group
    Campaign groups may now be created with objective type. If created with an objective type, then all campaigns in the group will share the same objective type. This field is optional and immutable once created.

  • Engagement Retargeting API: New engagement source types
    We are introducing the ability to build retargeting audiences based on their engagement with the Document and Conversation ad formats. Once an engagement rule is created, these audiences will refresh automatically based on the trigger and time frame selected. Advertisers can use audience retargeting to stay top of mind and move their target audiences through the funnel.

  • AdAnalytics API: Reminder to switch to approximateMemberReach field

If you are still utilizing the old field, please note that we will be updating the approximateUniqueImpressions measurement methodology to align more closely with approximateMemberReach.

  • Changes to Member Groups’ Targeting in the EEA and Switzerland As part of our ongoing efforts to provide a safe and trusted platform for members, we disabled Member Groups’ targeting within the European Economic Area (EEA) and Switzerland (CH) as of May 15, 2024. Our global advertising policies do not allow targeting sensitive groups on our platform, and this change further helps protect LinkedIn members, customers, and partners, as well as clarify LinkedIn's compliance with applicable laws in the region.

As a reminder, if you have created campaigns before May 15 that target the EEA or CH using Member Groups’ targeting, they will continue to deliver unless you make any edits. However, you will not be able to use this targeting facet for new campaigns targeting members residing in these regions. If your campaigns only target countries outside the EEA and Switzerland, you are not impacted by this change.

There are multiple ways advertisers can reach their desired audiences on LinkedIn and meet their marketing goals. We encourage you to review our targeting best practices to learn more about optimizing your campaigns.

May 2024 - Version 202405

Product & Platform Announcements

  • Changes to Member Groups’ targeting in the EEA and Switzerland starting May 15, 2024
    As part of our ongoing efforts to provide a safe and trusted platform for members, we have decided to disable Member Groups’ targeting within the European Economic Area (EEA) and Switzerland (CH). We have global advertising policies in place that do not allow targeting sensitive groups on our platform. This decision helps protect LinkedIn members, customers, and partners as well as clarify LinkedIn's compliance with applicable laws in the region.
    Starting May 15, 2024, you may experience changes in the LinkedIn campaign creation process if you run campaigns targeting members residing in the European Economic Area (EEA) and Switzerland (CH). Please review the following to understand how this change impacts your customer campaigns:
Campaigns created before May 15 that target the EEA or CH AND Member Groups - Campaigns will continue to deliver and edits can continue to be made.
- On or after May 15: Edits to these campaigns will require the removal of Member Groups or EEA & CH targeting to be able to save and activate.
Campaigns created on or after May 15 that target the EEA or CH Member Groups’ targeting will no longer be available.

If campaigns only target countries outside the EEA and Switzerland, these changes do not apply. There are multiple ways advertisers can reach their desired audiences on LinkedIn and meet their marketing goals. We encourage you to review our targeting best practices to learn more.

    • Reporting for Connected TV Ads
      We have introduced CONNECTED_TV as an additional value supported on the IMPRESSION_DEVICE_TYPE pivot for both the analytics finder and the statistics finder. When this pivot is used, ad performance metrics will be grouped by the device type the ad made an impression on, such as DESKTOP_WEB, MOBILE_WEB, MOBILE_APP, CONNECTED_TV, and UNDETECTED. Learn more about the reporting by impression device type in Campaign Manager here.

    • Reporting for New Qualified Leads Conversion Rule
      We have introduced new metrics qualifiedLeads and costPerQualifiedLead to the statistics finder. The qualifiedLeads metric will show the total count of qualified leads attributed to the entities in the given time range and costPerQualifiedLead will return the number of qualified leads divided by spend. Partners can now submit this new conversion rule, QUALIFIED_LEAD, through the Conversions API as noted above.

For example, allowlists can only be applied as an allowlist. Read more about the definitions and different use cases of these lists here.

LinkedIn in Europe: Changes for the Digital Markets Act
Starting in February, LinkedIn made changes for members in the EEA and Switzerland to comply with new requirements imposed on us by the Digital Markets Act (DMA). We are providing the ability for members in these regions to choose whether to connect their core LinkedIn experience with LinkedIn marketing products and services in order to better tailor their experiences to their professional interests. As this new experience ramps to members, your customers may notice changes in LinkedIn campaign performance. For example, if you use LinkedIn Reporting API, they may notice fewer conversions reported based on how we apply modeling to report conversions from members residing in the EEA and Switzerland. Or if they use certain targeting facets such as inferred targeting or retargeting from company Page visits and events, they may observe decreased audience sizes that could result in changes to ROI.

The changes you observe are a reflection of members in the EEA and Switzerland who have either not yet engaged with the new consent experience or have chosen not to connect their Marketing Solutions feature to their core LinkedIn experience. The impact is highly variable based on DMA consent rates, targeting usage & behaviors (e.g. AND vs OR, hyper targeting), budgets, and more. Read more about our approach to DMA here and how this may change our marketing solutions products and services here.

Ad Analytics API: Upcoming Reach Metric Changes
Starting in January 2024, approximateUniqueImpressions will be deprecated and the new API field will be called approximateMemberReach. As we move to a new metric measurement methodology, you may see some deviation between upcoming approximateMemberReach and old approximateUniqueImpressions for the same creative/campaign/campaign group with the same date range. Additionally, we will be restricting the availability of approximateMemberReach metrics in the following ways:

  • approximateMemberReach will only be supported with pivot(s): CREATIVE, CAMPAIGN, CAMPAIGN_GROUP, CAMPAIGN_TYPE, OBJECTIVE_TYPE and/or SERVING_LOCATION. All requests which supply additional pivot(s) will not include approximateMemberReach in the response.
  • approximateMemberReach can be requested for date ranges with a maximum range of 92 days.

Lookalike Audiences API: Sunset on February 29
On February 29, 2024, we will sunset the ability to create new Lookalike Audiences in both Campaign Manager and via API, as we evolve our audience solutions and invest in new solutions to help scale marketers’ first- and third-party data. Existing Lookalike Audiences can still be used in campaigns but will not be updated when the seed audience updates. Additionally, the following changes will impact existing audiences:

  • If the LaL audience is not used in a draft or active campaign for 30 days, it will be ARCHIVED.
  • If an LaL audience is ARCHIVED but added to a draft or active campaign, it will go back to BUILDING but it will not be regenerated. It will reflect the original state of the LaL as it was prior to February 29.
  • If an ARCHIVED LaL audience is EXPIRED, it is purged and can not be reused.

June 2023 - Version 202306

Migrations

Critical API migrations must be completed by June 30, 2023.

  • API Versioning and new Content APIs: We will sunset unversioned APIs and legacy Content APIs (Shares API, UGCAPI) on June 30, 2023. Migrate to versioned APIs and new Content APIs to avoid any disruptions.

  • New Community Management API*: We introduced a new Community Management API in January 2023 to offer more functionality to enable your customers to grow their professional communities. Apply and migrate to the new API to keep your community management integration active. Legacy community management permissions will sunset and be removed on June 30, 2023

Product & Platform Announcements

  • Audience Insights API: Make it easier to plan and understand professional audiences We are introducing the Audience Insights API, which provides aggregated insights into the demographic and firmographic details, and interests of a target audience. These insights help you understand more about “who” the audience is and can be leveraged to discover new audiences, plan & optimize your strategy, and build new audiences to seamlessly start your campaign. This is a private API and requires additional approval to access. Learn more on how to apply here.

  • Ad Analytics API: B2B query templates make it easy to get relevant reporting metrics
    Templated, B2B-focused queries are now available via Postman collection to enable quick access to B2B-relevant metrics that can be used to build insightful reports and inform optimization. We are starting with 3 focused bundles - Performance Overview, ABM Performance Overview, Conversions Deep Dive - and will continue to evolve our templates library, so please take advantage and share feedback here for future updates.

  • Response format change for thirdPartyTrackingTags API
    Starting with version 202306, we're making changes to the response format of the thirdPartyTrackingTags API. The GET and FINDER APIs will now return changeTimeStamps instead of changeAuditStamps in their responses. The new changeTimeStamps will still include the created, lastUpdated, and deleted fields, but they will now directly contain the timestamp value instead of being nested within another object with a time field.

  • Query params changes: Enabling unwrapped query params
    We previously announced that certain query params had to be wrapped - e.g. we required intendedStatuses=(value:List(ARCHIVED,CANCELED)) rather than intendedStatuses=List(ARCHIVED,CANCELED). Based on your feedback and to create a better experience, we’ve decided to revert this decision and enable you to make requests without wrapping the query params. We will support both wrapped and unwrapped query params until the 202305 version. From 202306 onwards only unwrapped query params are allowed. The APIs that are affected by this change are: Ad Analytics API, Creatives API, Posts API, Saved Audience Template API, Videos API.

May 2023 - Version 202305

Migrations & Breaking Changes

  • Critical API migrations must be completed by June 30, 2023.
    Please review details below for recent API enhancements that may impact your apps.

If you have impacted apps, please make the necessary changes immediately or set aside time/resources to complete updates before June 30th 2023.

  • Migrate June 2022 versioned APIs to the latest version prior to June 15, 2023
    Beginning June 2022, we introduced monthly versioning of our APIs and committed to supporting each monthly version for 12 months. Applications using the 202206 version of any versioned APIs must migrate to the latest version before June 15, when we will release the June 2023 versions of our APIs.

  • Reminder about access and refresh token requests after June 30, 2023
    All access token and refresh token requests should be made using only the POST method to /accessToken endpoint with the request header “Content-Type”: “x-www-form-urlencoded” and all required parameters in the request body. We will start returning 400 errors on the GET /accessToken endpoint after June 30, 2023.

  • Update to adCreativesV2 deco Starting May, all deco calls for creative URN will resolve via the /creatives endpoint instead of the /adCreativesV2 endpoint. Partners who use the adAnalytics endpoint and other endpoints that use deco calls to fetch creatives need to update their calls.

  • Message Ads API We’re sunsetting Message Ads API starting May 22, 2023. New campaign creation will be disabled on June 19, 2023. We strongly encourage switching from the legacy Message Ads API to Conversation Ads API by June 19th to avoid disruption of campaign delivery.

  • Updates to Base URLs Starting with the 202305 version, all API calls to the following endpoints will be modified to include advertiser Account ID in the URL path:

Endpoint Changed Previous Base URL New Base URL
/adCampaignGroups https://api.linkedin.com/rest/adCampaignGroups https://api.linkedin.com/rest/adAccounts/{adAccountId}/adCampaignGroups
/adCampaigns https://api.linkedin.com/rest/adCampaigns https://api.linkedin.com/rest/adAccounts/{adAccountId}/adCampaigns
/creatives https://api.linkedin.com/rest/creatives https://api.linkedin.com/rest/adAccounts/{adAccountId}/creatives

What this means:

  • Finder functionality will now be limited to a single account. Currently, we can search for campaign groups, campaigns and creatives across accounts using finders. Adding advertiser account ID to the URL would limit the ability to do this. Any calls from now on need to be made per account.

  • In addition, we will be removing the ability to filter by account predicate from campaign group, campaign and creative finders. As we are already limiting the finder functionality to a single account, it doesn’t make sense to have it as a filter predicate. Similarly, we can no longer sort by Account field since the search results are being limited to an advertiser account.

  • The new URLs will be active from the May version. This means that all APIs using version header 202304 or earlier will need to call the old URLs. And all APIs using version headers 202305 or above will need to call the new API URLs.

  • With the new APIs, applications will always need to pass an advertiser account ID in the URL path.

  • Ad Analytics API

    • Deprecate API Decoration starting with the June 2023 version: Starting with the 202306 version, we will remove API Decoration from the Ad Analytics API. As an alternative, individual requests can be made to access the corresponding entity associated with a URN. More information can be found in URN Resolution. For eligible pivots of the Ad Analytics API, we are adding a note that indicates which type of URN will be returned for each pivot. For example, if the MEMBER_COMPANY pivot is used with an analytics finder, then the response will contain a pivot value in the format urn:li:organization:<organizationId>.
    • Remove support for pivot and pivotValue fields: Starting with the 202305 version, we will no longer support the pivot and pivotValue fields in the returned entities of the Ad Analytics API. Requests with these fields in the field projections will be rejected. We will continue to support pivotValues, which provides more accurate and comprehensive information about the values of the pivots requested.

Product & Platform Announcements

  • Content API: Externalizing Document Ads In September 2022, we rolled out a new ad format, Document Ads, which allows advertisers to share ungated and gated documents, such as case studies, white papers, or research reports, directly in the LinkedIn feed. With Document Ads, target audiences can read or download documents without leaving the feed. Advertisers can choose to share their content freely to build awareness and grow thought leadership or gate their documents with a Lead Gen Form.

  • Document Ads API Prior to today, creating a Document Ad was only available to advertisers through Campaign Manager. The new Document Ads API allows advertisers to now have access to a new format during ad creation on partner platforms. To learn more, see the Document Ads API page.

  • Ad Analytics API: New metrics for Conversation Ads We’re launching a new & improved version of Conversation Ads on May 22nd, with availability increasing over time. Alongside this product change, we will introduce two new reporting metrics for Conversation Ads - headlineImpressions and headlineCTR - to help you measure campaign performance for new & improved Conversation Ads. These new metrics will measure the number of times members are shown the headline of the Conversation Ad and the number of times members clicked on it to start a conversation. To learn more, see this article.

  • Ad Segments API: find by account requests without start or count parameters are now paginated according to the standard pagination behavior.

Schema changes

  • Ad Targeting, Ad Targeting Entities API: Starting with the 202304 version, we're changing the format of certain query parameters in the adTargetingFacet finder, the similarEntities finder, the typeahead finder and the urns finder. In the finders, entityType, queryVersion, and fetchType would be records containing the expected values instead of directly accepting values. For example, entityType=SENIORITY would become entityType=(value:SENIORITY).

  • Ad Targeting, Ad Targeting Facets API: Starting with the 202304 version, we're changing the $URN field of type urn in the GET_ALL method to adTargetingFacetUrn of type AdTargetingFacetUrn.

Deco Updates

Product & Platform Announcements

  • Images API & Videos API: Beginning with the 202304 release, we are removing a role check for company URN owners and member URN owners when retrieving an image and/or video. For partners using a combination of /posts and /images or /videos, if /post API viewability checks are satisfied (e.g. you need to own the post as a member or company admin or be a role in AdAccount) you will be able to access images through /images and videos through /video.

  • Ad Analytics API:

    • Introducing IMPRESSION_DEVICE_TYPE pivot: Starting with the 202304 version, we are introducing the IMPRESSION_DEVICE_TYPE pivot for both the statistics finder and the analytics finder. When this pivot is used, the results will be grouped by the device type the ad made an impression on, such as MOBILE_APP and DESKTOP_WEB.
    • Deprecate API Decoration starting from the June 2023 version: Starting with the 202306 version, we are removing API Decoration from the Ad Analytics API. As an alternative, individual requests can be made to access the corresponding entity associated with a URN. More information can be found in LinkedIn Marketing API URN Resolution. For eligible pivots of the Ad Analytics API, we are adding a note that indicates which type of URN will be returned for each pivot. For example, if the MEMBER_COMPANY pivot is used with an analytics finder, then the response will contain a pivot value in the format urn:li:organization: <organizationId>

  • Ad Publisher Restrictions API: Externalizing the type field Starting with the 202304 version, we are introducing a new field type. This field can be used to create allowlist by passing type as ALLOWLIST in create method. This is an optional field having a default value as BLOCKLIST for backward compatibility since in earlier versions we supported only creation of BLOCKLIST from API. For example, “type”: “ALLOWLIST” can be used to create allowlist.

  • New training videos To support our developer community, we've started to produce training videos on topics we think you'll find helpful. Our first two cover:

March 2023

Product & Platform Announcements

  • Ad Analytics API: Introducing validWorkEmailLeads metric and PLACEMENT_NAME pivot Starting with the 202303 version, we are introducing the following:

    • validWorkEmailLeads: This metric represents the count of leads with a valid work email that does not use an established free or personal email domain.
    • PLACEMENT_NAME: This pivot enables grouping of metrics by placement. The pivot values are: LINKEDIN, OFFSITE and OFFSITE_IN_STREAM. Only LAN(Linkedin Audience Network) enabled video campaigns are eligible to deliver on offsite in-stream inventory. When video campaigns deliver on offsite in-stream inventory, you will see the metrics available for "OFFSITE_IN_STREAM" placement.

  • Image API & Videos API: Externalizing the Media Library In October 2022, we rolled out the media library in the Campaign Manager UI. The media library provides one location where advertisers can upload, manage, and select images and videos for single image ads and video ads. We are externalizing the media library for our API partners so that advertisers can use the same media library during ad creation on partner platforms.

    This will allow API partners to perform the following actions:

    • initializeUpload (existing method): This is an existing method for asset upload; the update in the release would be parallel registration under the Media Library

    • findByAssociatedAccount (new method): Return all media library assets under a specific account and asset type

    • partialUpdate (new method): Update an existing media library asset- specifically to rename an asset or to archive it

      We will enable findByIdsAndAssociatedAccount to return specific media library assets based on ID in a future release.

  • Saved Audience Template API: Save Audience Criteria
    We are introducing a new API to enable the following:

    • Save audiences, including targeting attributes and/or existing matched audiences, for easy re-use in campaigns. This is especially valuable for users who build audiences via the Audience Insights and wish to apply those audiences to a campaign.

    • Fetch audiences to access audience insights when used in tandem with the Audience Insights saved via the Campaign Manager UI.

  • Ads A/B Testing API: Test Campaign Performance
    We have launched A/B Testing to help our advertisers optimize their ROI with rigorous testing. A/B Testing measures the performance of two campaigns with equal audiences and budgets to test one variable, such as creative content / ad format, targeting, or placement. The testing tool then selects a winner (if any), or verifies that the performance difference between the variants is insignificant or inconclusive.

Breaking Changes

Starting with the 202303 version, we will change the format of certain query parameters in both the analytics finder and the statistics finder. In both finders, pivot, pivots, timeGranularity, campaignType, and objectiveType would be records containing the expected values instead of directly accepting values. For example, pivot=CAMPAIGN would become pivots=(value:List(CREATIVE,CAMPAIGN)) would become pivots=List((value:CREATIVE),(value:CAMPAIGN)).

Reminders

Results for all /posts finders (findByDscAccount and findByAuthor) will be sorted by last modified time in descending order (latest -> oldest) by default. This will help you manage post contents more efficiently.

  • Ad Analytics API: Sort reporting metrics
    The finder methods, Analytics and Statistics, of the adAnalytics endpoint now support two additional optional parameters: sortBy.field and sortBy.order. These parameters allow the results of these endpoints to be sorted in an ascending or descending order by one of the following fields: costInLocalCurrency, impressions, clicks, oneClickLeads, opens, sends, externalWebsiteConversions.

Breaking Changes

Make sure to migrate to the new APIs before February 28, 2023 when we will sunset the Shares and UGC APIs.

November 2022

Product & Platform Announcements

  • Engagement Retargeting API: Retarget an audience based on content engagement or member actions. The Engagement Retargeting API is available again starting with the November API version, after we removed the API in May due to a bug. You can retarget audiences based on content engagement or member actions such as company website or LinkedIn Page visits, engagement with Single Image Ads, Video Ad views, Lead Gen Form opens and more. We’ve also introduced more flexibility with website retargeting lookback windows, and added the ability to delete segments.

  • New methodology for Video Completion Rate: To align with the industry standard, we are changing how we calculate Video Completion Rate (VCR) for all videos across LinkedIn and the LinkedIn Audience Network (LAN) — from completions divided by views to completions divided by plays. Learn more about the definitions of these metrics here. VCR is a derived metric that is not shared in any APIs. However, if you are calculating VCR using data that is available via Ad Analytics API, we recommend updating the calculation to videoCompletions divided by videoStarts as a percentage.

  • Deprecating API decoration: Starting with the 202211 version, we will no longer support API Decoration for the adAccounts, adCampaigns and adCampaignGroups APIs; we will deprecate API Decoration for other APIs in future versions. To replace API Decoration, we are introducing additional fields in the schemas. Learn more about how to access these fields here.

  • A new, more focused inbox experience: We’re introducing a two-tabbed inbox in the LinkedIn platform so members can more easily find and respond to the messages that matter most. The Focused tab contains the most relevant messages, while the Other tab houses the remaining conversations. Sponsored Messages will be delivered to the Focused tab for members who have a higher propensity to click or submit a lead based on their past interactions with Sponsored Messages. Sponsored Messages will be delivered in the Other tab for all other members. No action is required. Please make note of this change as it may impact campaign performance. Learn more here.

Product & Platform Announcements

  • Offline Conversions API: A new API to measure the marketing impact on offline events The new Offline Conversions API gives you the tools to build a solution that enables you to attribute offline marketing data to more accurately measure the down-funnel effectiveness of ad campaigns - unlocking insights to improve ROI measurement and optimize performance. See this blog post to learn more about what you can build with this API, how it can benefit your customers, who this API is for, and how to apply for access.

  • Organization Follower Statistics API: New accurate and comprehensive follower data for Pages. Starting with the version 202210, the organization follower breakdown is replaced by legacy geo region and country with the Bing Geo market area and country/region. This will provide more accurate and comprehensive geographical data for Page followers. To avoid disruption and inconsistency in the naming conventions and follower counts across products, please take the following actions:

  1. Migrate to followerCountsByGeo or followerCountsByGeoCountry and to be able to read the Bing Geo URNs, which can be resolved by the Bing Geo API.
  2. Migrate to the new Industry Taxonomy Versions API, introduced in the September 2022 update, to resolve the industry V2 URNs in followerCountsByIndustry.
  • Ad Campaigns API: LinkedIn Audience Network offsiteDeliveryEnabled field now required. The LinkedIn Audience Network (LAN) helps you reach targeted professional audiences across multiple touch points and in different trusted environments to boost campaign performance. Starting with the version 202210, you will have to explicitly set the offsiteDeliveryEnabled field (now a mandatory) to be true or false, so that the LinkedIn Audience Network can be enabled across all eligible campaigns.

September 2022

Product & Platform Announcements

  • Ad Supply Forecasts API: New metricType values for cost per key result forecasting such as COST_PER_MILLION_IMPRESSIONS, COST_PER_MILLION_CLICKS, COST_PER_MILLION_VIEWS, COST_PER_MILLION_LEADS, COST_PER_MILLION_REACHES, and COST_PER_MILLION_MESSAGE_SENDS have been added to the /adSupplyForecasts API. This enables advertisers to understand cost per objective key result hypothetically based on their campaign set up, so they can better plan their campaign and budget use.

  • Brand Lift Results API: we’ve introduced two new values to understand statistical strength of Brand Lift test. First, statistical strength for Relative Brand Lift has been added as relativeLiftStatisticalStrengthMetrics to adLiftResultMetrics. Secondly, the statistical strength for demographic breakdown is now available as adLiftResultStatisticalMetrics in adLiftTestResultMetricMemberDemographicBreakdowns.

  • Industry Taxonomy Versions API: We’ve introduced a new API to better represent industry data on LinkedIn. It replaces the /industries API and queries industry data based on industry URNs. The new API offers a hierarchical structure to easily navigate the comprehensive list of industries available on LinkedIn. It supports the existing industry data and 400+ additional industry codes that are aligned with the North American Industry Classification System (NAICS).

  • New API Postman Collection workspace for versioned APIs only A new workspace dedicated for versioned APIs is now available to test newly released versioned APIs. Clicking on the “Try with postman” button from public developer pages links you right into this workspace. This change enhances the overall dev experience, searchability & tracking capabilities. Check it out.

Breaking Changes

  • Unversioned Ad Analytics API: approximateUniqueImpressions available again [in beta] In our July update, we communicated the removal of the approximateUniqueImpressions metric. As of September 12, 2022, we’ve reinstated this metric in the AdAnalyticsV2 endpoint, based on feedback from our partners and our customers. The reach metric will come with a new 92-day maximum window, meaning you will be able to pull the metrics on any dimension (e.g. campaign level, campaign-group level, etc.,) for any time range<=92 days. For all campaigns, the approximateUniqueImpressions metric is currently in beta, meaning that we’re still testing and iterating on it. During these iterations, the calculation of the metric can change. Therefore, we recommend using this metric directionally. We do not recommend using it for historical performance comparisons. Moreover, for campaigns running on our Audience Network, some traffic is excluded, so the metric may be underestimated — in some cases significantly. We will also deprecate the following approximateReach metrics from the unversioned APIs starting in October: averageDailyReachMetrics,averagePreviousDayReachMetrics, averagePreviousSevenDayReachMetrics, averagePreviousThirtyDayReachMetrics.

  • DMP Segments Lookalike API: Starting October 31, 2022, we will introduce 1 minute per user (a.k.a member) rate limits for our Lookalike API. The limits will be enforced such that there is minimal interruption to existing applications and their users. For more detailed information, see the rate limit specific sections of our FAQ.

  • Unversioned Industries API: Starting January 31, 2023, the /industries API will be deprecated. It has been replaced by the Industry Taxonomy Versions API. Requests made to /industries will receive a 404 status code error in response.

Product & Platform Announcements

  • Posts API

    • Create Polls and Multi-Image Posts to engage your community: Our new Posts API now supports the creation and retrieval of polls and multi-image posts, increasing the variety of content formats marketers can use to reach their audiences.

  • Dynamic UTM API/adTrackingParameters

    • Create a dynamic UTM parameter to effectively track campaigns: You can now attach dynamic and custom UTM parameters on supported creative URLs to understand your ad's effectiveness across platforms and to track all campaigns and creatives uniquely, even if duplicated from an existing campaign. These macros are automatically filled with LinkedIn platform values for a campaign, creative, account, and more. Moreover, you don't need to trigger numerous creative content changes for UTM tracking purposes, which overloads Ads Quality with creative edit history and large review queues. Sponsored Content (Image, Article, Video) will be supported with this change. Support for Dynamic Ads, Carousel, and Message ads will come later. All partners using Shares and UGC APIs exclusively for UTM purposes, should now use this new API and avoid duplicate UTM assignments due to more than one method. Previous static UTM assignments will be preserved, but moving them from content to campaign is advisable using this API.

  • Brand Lift API

    • Get brand lift survey results broken down by member age and gender demographics: Two new values MEMBER_AGE_RANGE and MEMBER_GENDER are added to AdLiftTestMemberDemographicCategory Enum. You can now see raw survey results and lift metrics broken down by member age range and gender demographics (assuming that there are enough data points, according to our privacy thresholds). Start reading the new enum values to see member age and gender demographics for the adLiftTestResults.

Breaking Changes

  • Ad Analytics API
    • approximateUniqueImpressions removed on July 31: On June 8, we launched 9 new metrics on the versioned & unversioned Ad Analytics API to replace the approximateUniqueImpressions metric. These new metrics are contained within the averageDailyReachMetrics, averagePreviousSevenDayReachMetrics, and averagePreviousThirtyDayReachMetrics sub-records and will approximately reach, frequency, and cost per 1,000 member accounts reached for three fixed time ranges: the current day, the last 7 days, and the last 30 days. You’ll be able to pull these metrics for any day. approximateUniqueImpressions will be removed on July 31, 2022 from the API, and any calls with this metric will result in a 404 error.

These new metrics are contained within the averageDailyReachMetrics, averagePreviousSevenDayReachMetrics, and averagePreviousThirtyDayReachMetrics subrecords and will approximate reach, frequency, and cost per 1,000 member accounts reached for three fixed time ranges: the current day, the last 7 days, and the last 30 days. You’ll be able to pull these metrics for any day. For example, you can pull the “average last 7-day reach” for October 25, (which covers October 18 - October 25), for October 24 (which covers October 17 - October 24), and selecting October 24 - October 25 will average the two individual last 7-day counts. approximateUniqueImpressions will be removed July 31, 2022.

Within the LinkedIn Campaign Manager UI, LinkedIn Audience Network is enabled by default, and we’re updating the API accordingly. This means that the default value for offsiteDeliveryEnabled will change from false to true for new campaigns. If you support our Audience Network in your platform, please ensure that the option for it is also set as true by default so that advertisers can continue to benefit from reach and scale efficiencies. If you do not support our Audience Network, make sure this field is set to false to avoid having ads being served on it.

  • Removal of campaign floor price (unitCost field)
    • Who’s impacted: Partners using the Ad Campaigns API or Ad Budget Pricing API
    • What’s happening: We are removing the floor price for manual bidding campaigns. Beginning on July 18, when creating manual bidding campaigns, advertiser campaigns now must satisfy two criteria: a bid must be greater than 0 and cannot exceed bidLimits.max. Previously, bids had to be greater than bidLimits.min, which is returned by the Ad Budget Pricing API. If you are using bidLimits.min as a requirement for unitCost, you no longer need to and only need to ensure bids are greater than 0. If an advertiser tries to create or update a campaign to have bid > 0 and below bidLimits.min, this will no longer return an error. The campaign would be created successfully.
  • Brand Lift Test Benchmarking released
    • Who’s impacted: Advertisers currently adopting or will adopt the Brand Lift Test API

  • LinkedIn’s privacy-first approach to B2B digital advertising
    • Who’s impacted: All partners
    • What’s happening: In case you missed it, last month we shared our privacy-first approach to B2B digital advertising. We are introducing new approaches that help provide online consistency across channels and devices, all while limiting or even eliminating the use of third-party personal data including: testing Group Identity for B2B leveraging our first-party data and further investing in B2B measurement.

  • [reminder] Sponsored Messaging EU Targeting Restrictions
    • Who’s impacted: Partners using the Message Ads API or Conversation Ads API
    • What’s happening: We are stopping the display of Message and Conversations Ads to EU members effective starting January 10, 2022 for new and existing campaigns.

    • Who’s impacted: Partner using the Insight Tag API
    • What’s happening: In light of changing regulations on privacy, we are asking customers to enable “enhanced conversion tracking” for all LinkedIn Campaign Manager accounts. “Enhanced conversion tracking” allows first-party cookie tracking to minimize impact to their campaign performance due to privacy changes. If a customer uses LinkedIn Insight Tags, we recommend they enable “enhanced conversion tracking” in Campaign Manager. If a customer uses site-wide image pixels, we recommend they switch to Insight Tag and enable “enhanced conversion tracking”. There is no impact to your integration. More information can be found in this help center article.

November and December 2021

For this release, we are happy to share our perspective on the changing privacy landscape and our privacy-first approach to B2B digital advertising. First, we are introducing new approaches that help provide online consistency across channels and devices, all while limiting or even eliminating the use of third-party personal data. We’re beginning to test Group Identity for B2B leveraging our first-party data to group members together based on shared professional identity attributes, such as seniority and industry. Second, reaching your audience is only one part of effective digital advertising - B2B measurement must evolve, too. As part of the many paths that we’re exploring, we also are applying technologies to measure campaign success including: collecting conversions using first-party cookies, using artificial intelligence to measure conversions, and attributing offline conversions.These are a few of the solutions we’re testing, and we’ll continue to update you through this monthly newsletter.

  • Introducing Roles & Permissions
    • Who’s impacted: Partners using the Organization Access Control API
    • What’s happening: New Roles & Permissions on LinkedIn Pages make it easier than ever for teams to work remotely and collaboratively. Now admins can take one of three new roles within an organic hierarchy to access their Page and maintain distributed access with increased security. Through this new API, partners will check permissions for each user and match the user’s access level determined by their assigned role on the Page. Learn more
    • There are three new roles introduced in Organization Access Control API, including:
      • Content admin – has permission to create and manage Page content, including updates (as well as boosting updates), Events, Stories, and jobs.
      • Curator – has permission to view Content Suggestions, create recommended content, and view and * export Page analytics.
      • Analyst – has permission to monitor the Page’s performance through analytics to help drive goals.
    • The new Organization Authorizations API (/organizationAuthorizations) can be used to implement the same permission checks as the Organization Access Control API (/organizationsAcls). Please refer to the Role to Permission Mapping table in Getting Started, or see the Overview Page to learn more.

Campaign Management

  • Sharing an update on our plans for IDFA
    • One of the bigger industry shifts is Apple’s upcoming changes to Identifier for Advertising (IDFA), which companies use for tracking and ad targeting. We are committed to privacy-by-design principles that deliver value to our shared customers. As such, we have decided to stop our iOS apps’ collection of IDFA data for now. Although this change affects the LinkedIn Audience Network (LAN), Conversion Tracking and Matched Audiences, we expect limited impact to campaign performance. Our plan is to leverage our first-party data to help marketers reach buyer groups, which are critical for success in B2B marketing. We’ll update you next quarter on our progress and will share what we’ve learned along the way. Learn more.
  • Change to ad review rejection reasons
    • Who’s impacted: Partners using the Ad Creatives and Ad Forms API
    • What’s happening: LinkedIn does not allow ads that could capitalize from, exploit or sensationalize the currently monitored sensitive event. Therefore, we've added two new rejection reasons: prohibited political content and current sensitive events. We have also deprecated the existing reasons: prohibited political or religious content.

    • What’s happening: Starting May 31, 2021, for article type posts the description, title, and thumbnail fields will be set from LinkedIn’s URL Preview of the URL only if the description, title, and thumbnail are not provided from the API call. Prior to this change, each field was set from LinkedIn’s URL Preview if the specific field was not set. This feature has always been the best effort and when fields are not present in the URL Preview, then it will not be set. If a specific representation of the post is desired, then it is recommended that partners set the description, title, or thumbnail fields rather than rely on automatic preview from this feature. LinkedIn provides Post Inspector, a tool to determine what LinkedIn’s URL Preview looks like. The tool uses slightly different naming. The three fields can be found under Properties with description and title named the same and Image corresponding to thumbnails.
  • [Reminder] Shares and UGC Posts Article Thumbnails
    • Who’s impacted: Partners using the Shares and UGC Posts APIs

The specific fields impacted are thumbnails in the ShareMedia of UGC Posts and thumbnails in ShareContent of Shares. If the first thumbnail does not have the required url field set and thus is invalid then this will result in no thumbnail regardless of if there are any thumbnails beyond the first.
  • [Reminder] Shares and UGC Posts Validations

  • Changes to targeting combination due to Apple’s App Tracking terms
    • Who’s impacted: Partners who target member interest & traits AND with Matched Audiences of types contact list, marketing automation contact list and website retargeting.
    • What’s happening: As per Apple’s App Tracking (ATT) legal terms we cannot link information inferred from user activity data on iOS app with any third party data for the purposes of ad targeting. With this, we are preventing customers from including or excluding a contact list, contact marketing automation or website segment with a member interest or trait targeting segments.
    • What does this mean for your application?
      • New campaigns created with the targeting combination mentioned above will fail with the following error:
      • Error code: INCOMPATIBLE_TARGETING_COMBINATION_FOR_ APP_TRACKING_TRANSPARENCY
      • Error message format: Facet {field1} with value(s) {value1} cannot be AND'ed together with {field2} to comply with app tracking transparency requirements.
        • field1: the targeting facet being checked
        • value1: the targeting facet value corresponding to field1
        • field2: the facets that are incompatible with field1
      • Please refer to the API documentation for the list of incompatible combinations.

      • What does this mean for my application? If your application calls /dmpSegments/users or /dmpSegments/companies, you may get a HTTP 429 response if calling the endpoints too frequently, indicating that you are exceeding the rate limits.
      • How do I handle API calls that are throttled? Your application should be catching errors when making calls to /dmpSegment/users and /dmpSegment/companies and retry after a minimum of 1 second whenever you receive an HTTP 429 response.
      • Can I get the limits increased for my application? No, the limits we intend to enforce will not be customizable at an application level. However the limits will be enforced such that there is minimal interruption to existing applications.
      • My application creates a significant amount of automated API calls (eg. one time full data dump or weekly data pushes with large volumes followed by smaller traffic that contains diffs throughout the week). Will this rate limit affect my throughput ? If the volume of your automated traffic exceeds tens of millions, then you can expect to see frequent throttling. While this might affect the throughput of your API calls, you will not see any differences in the matched audience processing SLA.
