Meta Custom Audiences

    Connect your Meta Ad Account to enable the daily Custom Audience sync. See the full feature guide under Marketing → Meta Custom Audiences; this page covers the one-time setup.

    Requirements

    • A Meta Business Manager with an Ad Account you own or have admin access to.
    • A system user access token with the ads_management scope (the CAPI-only scope ads_read isn't enough to write audiences).

    Setup steps

    1. Open Integrations → Meta in the admin dashboard.
    2. Paste your Ad Account ID (looks like act_1234567890).
    3. Make sure your existing CAPI access token includes ads_management. If not, regenerate it in Meta Business Settings.
    4. Toggle Custom Audiences on.
    5. Create your first audience from Marketing → Meta Audiences.

    Privacy & hashing

    Email and phone are normalised (lowercase, trimmed, E.164 for phone) and SHA-256 hashed before being sent to Meta. Raw PII never leaves the platform.
