# Update Asset Group

> Fallback Microsoft Ads asset group update tool for Performance Max asset groups

Fallback Microsoft Ads asset group update tool for Performance Max asset groups. This calls REST UpdateAssetGroups with PUT /AssetGroups, but sends a partial AssetGroup object: the runner supplies CampaignId and AssetGroups\[0].Id, then merges only the fields in update\_payload. Use care with nested asset collections like Headlines, Descriptions, or Images because Microsoft replaces the entire submitted collection. Supports dry-run review.
