Authorization: Bearer sk_live_... — your Adspirer API key (required)Content-Type: application/json (required)Idempotency-Key: <uuid> — recommended for write operations to make retries safeAll tool arguments are wrapped in an arguments object.
| Field | Type | Description |
|---|---|---|
account_id | string optional | Microsoft Advertising ad account id (numeric AccountId — NOT the 8-character account number shown in the UI). Get it from list_microsoft_accounts. Required when more than one account is connected; may be omitted with exactly one. `customer_id` is accepted as an alias. If the tool replies that several accounts are connected, re-run with this set — that reply is NOT a connection problem. |
customer_id | string optional | Alias of account_id. |
campaign_id | string required | The EXISTING Performance Max campaign to add asset groups to (required). PMax uses asset groups instead of ad groups/ads. |
asset_groups | array required | Performance Max asset groups. Each (when NOT associated with a Merchant Center store): {name (req), business_name (req, ≤25 chars), call_to_action (req — LearnMore/ShopNow/SignUp/GetStarted/...), final_urls (req, [url]), headlines (req, 3-15 strings), long_headlines (req, 1-5 strings), descriptions (req, 2-5 strings), images (req — at least 1 LandscapeImageMedia and 1 SquareImageMedia). Each image: {sub_type (LandscapeImageMedia/SquareImageMedia/LandscapeLogoMedia/SquareLogoMedia/ImageMedia1x2/4x1/...), and ONE of: image_url (a public https image URL — the backend downloads it and uploads to Microsoft automatically; Microsoft cannot read a URL directly), asset_id (an existing Microsoft media id from discover_microsoft_media), or data_base64. Optional crop_x/crop_y/crop_width/crop_height}. Optional: videos ([{video_url (public https — Microsoft fetches it server-side) OR video_id (from validate_and_prepare_microsoft_assets), description?}] — note Microsoft may reject video on an asset group as not-yet-available; any rejection is reported per asset group), path1, path2, start_date, end_date, search_themes ([strings]), tracking_url_template. Created PAUSED.} |
