ASC and AAC deprecation MAPI V25.0

Automation Unification drives App, Sales and Leads campaigns to default to the optimal, automation-first Advantage+ setup and allows advertisers and partners simplified access to Meta’s latest and most performant automation products. We are executing a phased deprecation of the legacy APIs and migration to the new Automation Unification, Advantage+ setup for Marketing API developers.

From V25.0 (18th February 2025) ASC and AAC campaigns can no longer be created or updated using the Marketing API, this will extend to all MAPI versions after 90 days (by May 19th 2026).

In V26.0 (estimated September 2026) all remaining ASC and AAC campaigns will be paused.

ASC or AAC campaigns utilizing Existing Customer Budget Caps (ECBC) will remain editable until V26.0, this feature is not available with Advantage+ campaigns. Developers with an ECBC campaign should take action using one of the below methods to replicate ECBC campaigns before V26.0:

1. Manual Duplication: Open an existing ASC/AAC campaign with ECBC in Ads Manager, you will be prompted to ‘Duplicate Campaign’. This 1-click step will create a new campaign that replicates the setup of the existing one.
2. Replicate ECBC campaigns using the API, use the guidance provided in developer documentation to replicate the campaigns using the API, here.
3. Request bulk migration at the ad account level, for managed partners we are able to provide a one time action to replicate all ECBC campaigns on an agreed date. Please reach out to your Meta POC and provide the Account IDs and preferred date to migrate.

Note: Note all ECBC campaign duplications will result in a new campaign ID.

This change affects the following endpoints:

• POST /{campaign-id}
• POST /{campaign-id}/copies

Please review the updated developer docs and FAQs to see all details of this change.
