What breaks next
Dated changes still ahead, soonest first. API versions reach end of life on published dates — this is the list to plan a quarter around.

Opt out of Advantage+ audiences manually during new ad set creation if strict targeting is required. Update bidding API calls to use ig_user_id instead of instagram_actor_id, and stop sending the canceled Special Ad Category certification fields (is_sac_cfca_terms_certified and is_eligible_for_sac_campaigns).

Migrate Advantage+ campaign creation to the new API workflows to avoid disruption. Create future Messenger lead ads via Ads Manager instead of the API. Resolve any flagged custom audiences before January 6, 2026, to ensure they can still be updated.

Update reporting to use new media view metrics before v26.0 is released. Stop using the metadata=1 query parameter by May 19, 2026. If using Webhooks mTLS, update your server trust store to include the new Meta Certificate Authority by March 31, 2026.
