Get one ad group
Gives the payload the provider reports for one ad group, exactly as the provider sent it: targeting, schedule, bid strategy, optimization goal, and everything else AdCrunch does not model. The budget is normalized on every listed row.
The keys are the provider’s, and so is the shape. A Meta ad set answers targeting, daily_budget and optimization_goal; a TikTok ad group answers budget_mode and placement_type.
When there is nothing to give
200with an empty body — AdCrunch does not know this ad group, 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 ad group but holds no stored payload for it.
/observe/{advertiserId}/ad-groups/{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.
