We've recently launched a feature for developers to start integration with the on-behalf-of (OBO) relationship for ad accounts. The benefit of doing so unlocks features for the ad account owners, including Custom Audience sizes and use of the audience overlap tool.
We're introducing 6 new endpoints to help developers enable the business OBO relationship for ad accounts:
POST endpoint to create new OBO requests, where the caller needs to specify the end business ID and business asset ID (Ad Account ID)
GET endpoint to view an OBO request
GET endpoint for viewing OBO requests of an ad account
GET endpoint for viewing received in-progress OBO requests of a business
GET endpoint for viewing sent in-progress OBO requests of a business
DELETE endpoint to cancel existing in-progress OBO request
Learn how to get started with the Business OBO feature.
