# Update ad-group assets

`PUT /v1/ads/ad-sets/{adSetId}/assets`

Edits existing Google assets in place. Send updates with assetResourceName and the fields to change. An asset is shared: changes affect every attachment using it. Omitted fields stay unchanged. The operation consumes the Google operations budget and invalidates affected cached lists.
