Graph API Version

Application Custom Audience Third Party Id

Retrieve an App User ID for the app's Facebook user.

Reading

An edge linking the application to the node representing the current user with fields useful for creating custom audiences.

The App User ID returned is an encrypted encoding of the Facebook user's ID and the App ID of the Facebook App making the call. This App User ID is used to create custom audiences for ad targeting.

Multiple calls to this endpoint for the same Facebook user will return different values. Therefore, the App User IDs cannot be used to correlate user behavior across devices or applications.
