Suggest Google Ads search themes

<Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Suggests search themes for a Performance Max campaign.

Search themes tell Google what the campaign is about when there are no keywords to match on. Nothing is saved: pass the ones you want to Create campaign.

You get at most 10 themes, each trimmed to 80 characters, and themes naming the platform itself are dropped. An empty list is a 200, so check the array rather than the status code.

<Note>This endpoint runs a language model and draws on a shared quota of 20 requests per minute per app, which every Google Ads AI endpoint debits. Enterprise workspaces get a higher quota. A 429 means the quota is spent, not that this endpoint has its own limit.</Note>

<Note>The copy is written in the language you send in the Accept-Language header. Omit the header and you get English — the app's own language is not consulted — so send it explicitly for a non-English app.</Note>

<Note>This endpoint accepts a personal API key. Workspace API keys are not authorized for it and are rejected with a 403.</Note>
