Issue

When attempting to sync users to older, existing Facebook (Meta) custom audiences via Segment, the synchronization fails. However, newly created audiences sync successfully. The following error response is returned from Meta:

(#200) The current user can not update audience <audience_id>

Status: 403

Type: OAuthException

Product

Twilio Segment

Environment

Segment Console

Cause

This error occurs due to a permissions mismatch or an ownership change within the Facebook Business Manager or the specific Facebook user account connected to Segment. While the currently authenticated user has the permissions required to create and sync new audiences, they lack administrative access to update older audiences that were created under previous account configurations or different owners.

Resolution

To resolve this issue, you must disconnect the affected audience and establish a new connection to generate a valid external audience ID under your current authenticated account credentials:

1. Log in to your Segment workspace.

2. Navigate to the affected audience that is failing to sync.

3. Disconnect or remove the connection to the Facebook (Meta) destination for that specific audience.

4. Re-establish the connection to the Facebook destination to create a new external audience. This action generates a new external audience ID tied to your current account.

5. Trigger a sync and verify that the new audience synchronizes successfully.
