Creatives

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.

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.

Ad image library

Lists the ad account's image library (Meta's `/act_X/adimages`), rows returned verbatim. The default projection covers hash, url, name, dimensions and status; `fields` is a raw-passthrough override. Any `hash` here is reusable wherever Meta accepts `image_hash` (e.g. `imageHash` on POST /v1/ads/creatives).
