Get one creative
Gives the payload the provider reports for one creative, exactly as the provider sent it: the image or video, the headline, the body copy, the call to action and the link.
When there is nothing to give
200with an empty body — AdCrunch does not know this creative, it belongs to another advertiser, or your organization does not own the advertiser in the path. They are deliberately not told apart.404— AdCrunch knows the creative but holds no stored payload for it.
/observe/{advertiserId}/creatives/{id}AuthorizationBearer token · headerrequiredSend Authorization: Bearer <credential>. Two credentials work.
An API key (acr_…) is what a server integration uses. Create one in the AdCrunch console under Settings → API keys — see https://docs.adcrunch.dev/account/api-keys. A key is bound to the organization that was active when you created it, and it keeps acting on that organization whatever you do later. It carries the permissions of the member who created it.
A session issued by the AdCrunch sign-in flow also works, which is how the console calls this service from the browser.
Either way the organization comes from the credential. There is no organization parameter.
