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.

Query Parameters

accountId*string

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

adAccountId*string

Meta ad account id (act_).

fields?string

Comma-separated Graph field override. Supports nested {} projections and Graph field modifiers, so a nested edge can be paged explicitly: without a .limit() modifier the expansion runs at the Meta default page size and the tail is dropped silently.

limit?integer

Rows per page

Range1 <= value <= 100
Default25
after?string

Cursor from paging.after of the previous page.

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).

List partnership ad content

Private beta. Lists creator Instagram posts available to the advertiser for Partnership Ads. Supply creatorUsername or postUrl. Requires instagram_branded_content_ads_brand permission and an advertiser Instagram Business Account.
