June 2023 - Version 202306

Migrations

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

  • API Versioning and new Content APIs: We sunset unversioned APIs and legacy Content APIs Shares API, UGC API 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're introducing the Audience Insights API, which provides aggregated insights into the professional 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'll 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 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.

Reminders

  • Access and refresh token requests after June 30, 2023. Make access token and refresh token requests using the POST method to /accessToken endpoint with the request header “Content-Type”: “x-www-form-urlencoded” and all required parameters in the request body. Using the GET /accessToken endpoint after June 30, 2023 will result in a 400 error.

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.
  • API versioning and new Content APIs*: Introduced in June 2022, these enhancements make it easy for you to build on our platform.
  • API versioning: Learn more and how to migrate from unversioned
  • New Content APIs: Learn more and how to migrate from legacy APIs.
  • New Community Management API*: Introduced in Q4 2022, this API accelerates access to more functionality enabling your customers to know and grow their professional communities. Learn how to migrate to the new API as well as our plans for community management.

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'll 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 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'll be removing the ability to filter by account predicate from campaign group, campaign, and creative finders. As we're 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'll 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're 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'll 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 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'll 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.

We start returning 400 errors on the GET /accessToken endpoint after June 30, 2023.

  • 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

Be sure to watch our helpful video on how to handle this change.

  • Update to adCreativesV2 for deco. Starting May, all deco calls for creative URN are resolving 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. All access and refresh token requests should only be made using the POST method after June 30,2023.

Product & Platform Announcements

  • Images API & Videos API: Beginning with the 202304 release, we're 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'll 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're 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're 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're 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're 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:

  • Best practices when working with our API support team

  • How to handle deprecation of API decoration (see related post in the Migrations & Breaking Changes section above for link).

March 2023

Product & Platform Announcements

  • Ad Analytics API: Introducing validWorkEmailLeads metric and PLACEMENT_NAME pivot Starting with the 202303 version, we're introducing the following:
  • validWorkEmailLeads: This metric represents the count of leads with a valid work email that doesn't 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'll 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 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 enable findByIdsAndAssociatedAccount to return specific media library assets based on ID in a future release.

  • Saved Audience Template API: Save Audience Criteria
    We're 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'll 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)).

  • Creatives API: Change in the structure of IntendedStatuses finder parameter**. Starting with the 202303 version, intendedStatuses query parameter in the finder request would be a record which would contain the expected array instead of directly accepting an array value. Instead of providing intendedStatuses=List(ARCHIVED,CANCELED) we would require passing intendedStatuses=(value:List(ARCHIVED,CANCELED)).

  • API Decoration Deprecation: In November 2022, we began deprecating API decoration for some APIs. Starting with the 202303 version, we'll no longer support decoration on the following APIs:

This 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.

  • Make sure when calling an API version to include the request header with key “Linkedin-Version” and set the value to correspond with the version you’re referencing using the YYYYMM format. Get started with this blog post, walk through video, or versioning documentation. Make sure to migrate before February 2023 when we'll sunset unversioned APIs.

  • New Content APIs that simplify the content creation experience and save you time. We introduced four new Content APIs that enable you to build quicker and to adopt the latest formats easier: Images, Videos, Post, and Creatives. With the new APIs, we’ve reduced the steps to upload creative assets and create posts; and the APIs are built to support your workflow. Get started with the new migration guide. Make sure to migrate to the new APIs before February 28, 2023 when we'll sunset the Shares and UGC APIs.
