Create a standalone creative

Creates a creative in the library WITHOUT an ad, reusable on the create endpoints via existingCreativeId. Provide exactly one of imageUrl (uploaded server-side), imageHash (from POST /v1/ads/images or the library list), or carouselCards (2-10 hand-built cards). The Page (and linked Instagram account, when present) is resolved from accountId as the story actor.

Ad video library

Lists the ad account's video library (Meta's `/act_X/advideos`), rows returned verbatim. The default projection covers id, title, status, poster frames, length and `source` (the playable MP4); `fields` is a raw-passthrough override. Any `id` here is reusable as `video.id` on the create endpoints, so N ads that differ only in copy share one upload. `source` lets you PLAY a video before picking it, which a poster frame alone can't settle when several videos share a first frame. It is a signed CDN URL that EXPIRES, so treat it as good for preview at selection time only — never persist it, re-list to get a fresh one. This is the only way to reach a video uploaded OUTSIDE Zernio (Ads Manager, another tool); videos we uploaded also come back as `creative.videoId` on GET /v1/ads. Meta transcodes asynchronously, so a row is only usable once `status.video_status` reads `ready`. Upload a new video via POST /v1/ads/videos, or inline via `video.url` on POST /v1/ads/create.

Creative details

One creative's details, verbatim from Meta. `fields` is a raw-passthrough override of the default projection.

accountId*string

Zernio SocialAccount id (posting or ads variant) used to resolve the Meta token and Page.

adAccountId*string

Platform ad account id (Meta act_, Google customer id, LinkedIn account id, ...).

Publicly reachable image; uploaded to the account's library server-side.

Existing library image hash (POST /v1/ads/images or GET /v1/ads/images).

urlTags?string

Appended to every outbound URL (e.g. utm_source=fb).

creativeFeatures?

Advantage+ creative enhancements: partial map of Meta creative feature keys (snake_case) to enroll status, forwarded as degrees_of_freedom_spec.creative_features_spec. Unspecified features default to OPT_OUT.

multiAdvertiser?string

Meta only. Multi-advertiser ads: whether Meta may show this ad alongside other advertisers' in one unit. Meta auto-enrols since Aug 2024, so send OPT_OUT to leave. It is a top-level creative field, NOT a creativeFeatures key — Meta rejects it there.
