Audiences

Update an audience

Update an audience. saved_targeting audiences accept name, description, and spec (full replacement, no merge, Zernio-only, no platform call). Platform audiences (uploaded/website/lookalike) accept name and description only, updated on the platform first and then mirrored locally; their rules are immutable, so spec returns 400 for them. Platform audience updates are Meta-only for now (other platforms return 501). Ads already created from a saved_targeting audience are unaffected, they snapshot the targeting at creation.

Get audience details

Returns the local audience record and fresh data from Meta (if available).

Delete custom audience

Deletes the audience from both the platform and the local database. `saved_targeting` audiences exist only on Zernio, so only the local record is removed.
