List Meta product catalogs

Lists the Meta product catalogs reachable from an ad account (owned + agency-shared catalogs of the ad account's business), for Advantage+ catalog ads (goal: catalog_sales on POST /v1/ads/create — e.g. vehicle inventory catalogs). Read-only; uses scopes customers already granted (no reconnect needed). Catalog contents (items, feeds) are managed in Meta Commerce Manager, not through this API.

List a catalog's product sets

Lists a Meta product catalog's product sets — the unit a catalog ad promotes. Pass the chosen set as `promotedObject.productSetId` on POST /v1/ads/create with `goal: catalog_sales`.

Creative library

Lists the ad account's creative library (Meta's `/act_X/adcreatives`), rows returned verbatim. The default projection covers id, name, status, object type, thumbnail, object_story_spec / asset_feed_spec and url_tags; `fields` is a raw-passthrough override. Any creative id here is reusable on the create endpoints via `existingCreativeId`.
