Meta Custom Audiences
The Meta Custom Audiences connector is a reverse connector: it pushes audience segments from your data warehouse to Meta (Facebook & Instagram Ads) as Custom Audiences. Use it to activate retargeting, exclusion, or Lookalike Audiences directly from your first-party data.
This connector handles Custom Audiences (CRM matching) only. To send server-side conversion events (Conversions API / CAPI), use the Meta Pixel (Reverse) connector.
