Update ad-group assets

Edits a Google ad group's existing assets in place; the change applies everywhere that asset is used.

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.

Attach ad-group assets

Creates sitelinks, callouts, structured snippets or image assets and attaches them to a Google ad group in one step. Creates and attaches sitelinks, callouts, structured snippets and image assets in one Google mutation. Google shows images only on accounts it deems eligible (account age, policy history, vertical).

Remove ad-group assets

Detaches assets from a Google ad group without deleting them, so they stay in the account and on anything else they are attached to. Google assets cannot be deleted. Other attachments remain. assetResourceNames is retained for compatibility. Fields go in the query string. A JSON body with the same fields is also accepted and, when sent, the query string is ignored.
