Suggest Google Ads text assets

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

Suggests text assets for a Performance Max campaign, one group per asset type you ask for.

Send asset_types with any of HEADLINE, LONG_HEADLINE, DESCRIPTION, BUSINESS_NAME and CALL_TO_ACTION_SELECTION. Only the types you ask for come back, so read the response by key rather than assuming all five are present. BUSINESS_NAME is a single string; the rest are arrays. CALL_TO_ACTION_SELECTION is a fixed set of values Google accepts rather than generated copy.

Nothing is saved. An asset type can come back as an empty array when the model returns nothing usable for it, under a 200.

<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>
