validate_and_prepare_microsoft_assets

Microsoft Advertising Write

Validate and upload images and videos to Microsoft, returning ready-to-use asset ids for the create tools

Endpoint

POST https://api.adspirer.ai/api/v1/tools/validate_and_prepare_microsoft_assets/execute

Headers

Description

Validate and upload images and videos to Microsoft, returning ready-to-use asset ids for the create tools. Pass images (each with a public https image_url + sub_type) and/or videos (each with a public https video_url). Images are downloaded and uploaded by the backend; videos are fetched by Microsoft from their URL directly (so even large videos move zero bytes through us). Call this BEFORE creating image/video ads or Performance Max asset groups so the create call gets clean asset ids.

Request body

All tool arguments are wrapped in an arguments object.

FieldTypeDescription
account_idstring optionalMicrosoft 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_idstring optionalAlias of account_id.
imagesarray optionalImages to validate + upload to Microsoft. Each: {image_url (public https — the backend downloads and uploads it), sub_type (LandscapeImageMedia/SquareImageMedia/...)}. Returns a Microsoft asset_id per image, ready to drop into an ad or asset group.
videosarray optionalVideos to add. Each: {video_url (public https — Microsoft FETCHES it server-side, so even large videos move zero bytes through us), description?, aspect_ratio?}. Returns a video_id per video.
