Ad Creatives

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.

multiAdvertiser'OPT_IN' | 'OPT_OUT'

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.
