[Legacy] Offline Conversions

  • Article

Warning

Deprecation Notice
The Marketing version 202304 (Marketing April 2023) and below has been sunset and the unversioned APIs are going to be sunset soon. We recommend that you migrate to the versioned APIs as well as migrate to the new Content and Community Management APIs to avoid disruptions. See the Migration page for more details. If you haven’t yet migrated and have questions, submit a request on the LinkedIn Developer Support Portal.

Offline Conversions allow you to onboard your offline conversion events to better measure your campaign performance. You achieve this by attributing offline conversions in addition to online conversions to provide a more accurate view of your return on ad spend and optimize campaign performance.

Note

This API has been sunset since November 2023, and last available version was 202310. We are not accepting new applications. To learn more, see the FAQ. If eligible, you may apply for access to the new Conversions API.

Permissions

There are two conditions for successful calls:

  • Scope permissions:

    • rw_offlineConversions for streaming conversion events
    • rw_ads for associating conversions to campaigns

  • User assigning permission holding one of the following roles in the Ad Account:

    • ACCOUNT_BILLING_ADMIN
    • ACCOUNT_MANAGER
    • CAMPAIGN_MANAGER
    • CREATIVE_MANAGER

Create a new Offline Conversion DMP Segment

To create a new offline events source, offline conversion segment must be created via DMP, a platform for you to upload and create audiences that you collect offsite. Alternatively, any existing offline conversion DMP Segment can be reused to stream offline conversion events.

POST /dmpSegments

Schema

Field Name Type Description
accessPolicy PRIVATE The default access policy of this DMP segment. Currently, the only accepted value is PRIVATE.
account urn The sponsored account urn that this DMP segment belongs to. Refer here to search for sponsored accounts that can be used.
description string (optional) A description for this DMP segment.
destinations LINKEDIN The destinations and various metadata that the content of this segment will be onboarded to. See DMP Segment Destinations. Currently, the only accepted value is LINKEDIN.
name string The name of this DMP segment. 
sourcePlatform string The source platform from where users profiles are being imported. A dedicated ENUM will be provided to approved partners when they are granted access to these APIs. 
sourceSegmentId string (optional) The foreign key on the source platform. This is an optional field that will be indexed and can be used by the source platform to find their segments.
type USER The content type of the profiles being imported into this DMP segment. Possible value is USER
sourceType CONVERSION Source type is an additional type for the segment's input data that is independent from DMPSegmentType. It is used to filter for offline conversion segments from other audiences and apply additional input validations. Currently, the only accepted value is CONVERSION.

Sample Request

POST https://api.linkedin.com/rest/dmpSegments

{
  "name":"Offline Conversion Events",
  "sourcePlatform":"DMP_PARTNER_PLATFORM", // Name will be provided.
  "account":"urn:li:sponsoredAccount:516848833",
  "accessPolicy":"PRIVATE",
  "type":"USER",
  "sourceType": "CONVERSION",
  "destinations":[
    {
      "destination":"LINKEDIN"
    }
  ]
}'

POST https://api.linkedin.com/v2/dmpSegments

{
  "name":"Offline Conversion Events",
  "sourcePlatform":"DMP_PARTNER_PLATFORM", // Name will be provided.
  "account":"urn:li:sponsoredAccount:516848833",
  "accessPolicy":"PRIVATE",
  "type":"USER",
  "sourceType": "CONVERSION",
  "destinations":[
    {
      "destination":"LINKEDIN"
    }
  ]
}'

Sample Response

A successful response returns a 201 Created HTTP status code and the segment ID in the x-linkedin-id response header.

Note

Once this Offline Conversion DMP Segment is created, it will be an empty segment, and we recommend inserting a timer to wait for at least 5 seconds after it is first created. It can then be used to stream any offline conversion events.

For more information including GET, UPDATE and DELETE methods, see DMP Segments - LinkedIn

Find Offline Conversion DMP Segments by Ad Account

Use the q=account query parameter and pass the sponsored ad account URN to find DMP segments by the associated sponsored ad account and use the sourceType=CONVERSION query parameter to filter on the offline conversion segments. For more granular results, you can add optional sourcePlatform and sourceSegmentId query parameters to the query.

GET /dmpSegments?q=account&account={sponsoredAdAccountURN}&sourceType=CONVERSION

Sample Request

GET https://api.linkedin.com/rest/dmpSegments?q=account&account=urn:li:sponsoredAccount:1234&sourceType=CONVERSION

    Batch Stream Multiple Conversion Events to the DMP Segment

    Tip

    • We recommend using the BATCH_CREATE request header to avoid hitting rate limits on POST by streaming multiple conversion events on the same POST request.
    • We support request payload size of 2 MB, so you should be able to send up to 5000 conversion events in a single batch request.

    Sample Request

    POST https://api.linkedin.com/rest/dmpSegments/{dmpSegmentId}/conversions
X-RestLi-Method: BATCH_CREATE

    If there is any invalid value in the request body like missing required field or invalid hash value in email, all records will fail and you'll need to resubmit the entire payload after correcting the data as indicated in the response body "message".

    Create Conversion Rules and Associate them to Campaigns

    To measure offline conversions, you must create a conversion rule for each conversion type passed in streaming conversion events in previous step for each conversion segment, and associate them to campaigns for attribution. Advertisers can also Set up Offline Conversion tracking in LinkedIn Campaign Manager.

    Create a Conversion Rule

    Similar to online conversion tracking, instead of defining URL match rules that are applicable for online conversions, advertisers will associate the offline conversion DMP segment created, where the offline conversion events are streamed for a specific conversion type.

    POST /conversions

    Schema

    Field Type Description
    account URN The Sponsored Account URN that this Conversion resides under. This can be either specified in URL query parameter or in the request JSON body.
    name string A short name for this rule, which will be shown in the UI and in reports.
    type string Type of the offline conversion to track for this conversion rule as used in streamed offline conversion event. Eg. PURCHASE, LEAD, SIGNUP etc. Complete list can be found here.
    dmpSegment URN DMP Segment URN that contains the offline events.
    associatedCampaigns Read only. Array of campaign URNs associated with this conversion. default=[ ] Campaign association needs to be done separately as shown in the next step.
    conversionMethod string For offline conversions, the only supported value here is OFFLINE_CONVERSIONS_UPLOAD
    postClickAttributionWindowSize int Conversion window timeframe (in days) of a member clicking on a LinkedIn Ad (a post-click conversion) within which conversions will be attributed to a LinkedIn ad. Allowed values are 1, 7, 30 or 90. Default is 30. Learn more
    viewThroughAttributionWindowSize int Conversion window timeframe (in days) of a member seeing a LinkedIn Ad (a view-through conversion) within which conversions will be attributed to a LinkedIn ad. Allowed values are 1, 7, 30 or 90. Default is 7. Learn more
    attributionType string The model that describes how conversion actions are to be counted. Acceptable values are: LAST_TOUCH_BY_CAMPAIGN and LAST_TOUCH_BY_CONVERSION
  • LAST_TOUCH_BY_CAMPAIGN (Each campaign): conversion actions are counted once for each campaign to which they can be attributed. (Default)
  • LAST_TOUCH_BY_CONVERSION (Single Campaign): conversion actions are counted once for each Conversion with at least one associated campaign. [Learn more] (https://www.linkedin.com/help/lms/answer/a426349)

    Sample Response

    • A 201 Created HTTP status code is returned if the request is successful and conversion rule ID in the X-LinkedIn-Id response header.
    • A 400 Bad Request is returned if the request does not pass the validation check. Please check the error message to understand what validation failed.

    For more information, see Conversion Tracking.

    Associate Campaigns to Conversion

    Campaign Conversions API is used to associate campaigns to a Conversion ID. Only the campaigns associated with the conversion are eligible for attributing tracked offline Conversions.

    PUT  /campaignConversions/(campaign:{sponsoredCampaignURN},conversion:{conversionURN})

    Sample Request

    PUT https://api.linkedin.com/rest/campaignConversions/(campaign:urn%3Ali%3AsponsoredCampaign%3A337643194,conversion:urn%3Alla%3AllaPartnerConversion%3A70203)

    {
  "campaign": "urn:li:sponsoredCampaign:337643194",
  "conversion": "urn:lla:llaPartnerConversion:70203"
}'

    PUT https://api.linkedin.com/v2/campaignConversions/(campaign:urn%3Ali%3AsponsoredCampaign%3A337643194,conversion:urn%3Alla%3AllaPartnerConversion%3A70203)

    {
  "campaign": "urn:li:sponsoredCampaign:337643194",
  "conversion": "urn:lla:llaPartnerConversion:70203"
}'

    A successful response returns a 204 No Content HTTP status code.

    Note

    • PartnerConversionURN is of the format urn:lla:llaPartnerConversion:ID where you need to replace ID with the conversion ID extracted from X-LinkedIn-Id response header when creating the conversion rule in this step.
    • Make sure to include X-Restli-Protocol-Version: 2.0.0 in the request header.

    For more information, see Campaign Conversions.

    Batch Create Campaign Conversions

    Multiple campaign conversions can be created with a Batch Create that accepts IDs parameter each with a campaign URN and conversion URN. The campaign and conversion URNs should be passed in a List format and encoded as shown in the examples below.

    PUT https://api.linkedin.com/rest/campaignConversions?ids=List((campaign:urn%3Ali%3AsponsoredCampaign%3A345396555,conversion:urn%3Alla%3AllaPartnerConversion%3A104004))

    {
