# Facebook Audiences v2

> Sync Masivo audiences to Meta Custom Audiences with automatic audience provisioning

## What is Facebook Audiences v2?

**Facebook Audiences v2** (`facebook-audiences-v2-destination`) syncs Masivo
audience membership into Meta Custom Audiences. One destination covers all
Masivo audiences: Meta Custom Audiences are created automatically per audience
using your ad account credentials.

<Info>
  Prefer v2 for all new setups. The legacy
  [Facebook Audiences](/guides/CDP/integrations/facebook-audiences/overview)
  destination (static `audience_id`) is deprecated.
