Description

🚨 **IF THIS TOOL RETURNS A QUOTA ERROR:** - The error message will include a clickable upgrade link - Show the FULL error message to the user (it contains the upgrade link) - DO NOT attempt to work around the error or use alternative data - DO NOT create campaigns or perform actions without valid tool data - STOP and direct the user to upgrade via the provided link Upload a new image and link it to a PMax asset group. Accepts http(s) URLs OR base64 data URIs (`data:image/...;base64,...`). Per-group caps are enforced BEFORE upload: 20 marketing images per group (across MARKETING_IMAGE / SQUARE_MARKETING_IMAGE / PORTRAIT_MARKETING_IMAGE / TALL_PORTRAIT_MARKETING_IMAGE), 5 of each logo type (LOGO / LANDSCAPE_LOGO / BUSINESS_LOGO). If the campaign has exactly one asset group, `asset_group_id` is optional — otherwise it is required. Image bytes are uploaded only after cap validation passes, so a doomed call doesn't burn bandwidth. **Parameters:** - campaign_id: The PMax campaign ID - image_url: http(s) URL or `data:image/...;base64,...` URI - field_type: which PMax image slot to fill (see list of accepted values) - asset_group_id: required for multi-group campaigns - asset_name: optional display name in the Asset Library **Execution time:** 3-8 seconds (image fetch + Google Ads mutate)
