Facebook Custom Audiences
Sync an Ours Privacy audience to Meta as a Custom Audience using your own Meta app and the hashed identifiers you choose to send.
Use this page to sync an Ours Privacy audience to a Meta ad account. Ours Privacy creates one Custom Audience per attached audience and replaces its membership daily.
Before you start
- A Meta ad account where the connected user can manage Custom Audiences, with Meta's Custom Audience terms accepted for the business.
- Your own Meta app with the Marketing API permission to manage audiences, and
https://app.oursprivacy.com/integrationsadded to its valid OAuth redirect URIs.
Set up the destination
- In Destinations, add Facebook Custom Audiences.
- Enter your Meta App ID and App Secret.
- Select Connect Meta Ads and complete the sign-in.
- Enter the Ad Account ID, digits only.
- Turn on the identifiers you want to send: email, phone, name and location, date of birth, gender. All start off.
- Save and publish.
Reconnect the destination if Meta revokes the connection or its permissions change.
Sync behavior
Each enabled identifier is hashed before upload. Members with none of the enabled identifiers are skipped. Meta never receives your conditions or internal name.
Each daily run replaces the prior membership, so people who no longer match are removed. The Custom Audience is labeled with the audience's Export Name, which is visible in Ads Manager and must not describe health information or another sensitive characteristic.
Meta can take time to process an upload, and its matched count is usually lower than the delivered count. Check Ads Manager for the platform-side figures.
Next Steps
- Syncing to destinations to attach this destination to an audience.
- Audience Destinations for how audience syncing works.
