Link or unlink asset group assets

Link existing assets or new content to the asset group, and unlink assets, in one atomic request. Links are applied before unlinks, so swapping the last asset of a role does not trip Google's per-role minimum. Unlinking removes the link only; the asset stays in the account library. validateOnly: true validates without writing.

Remove a Performance Max asset group

Removes the asset group on Google (status REMOVED, not reversible). Pass validateOnly=true to validate without removing.

Replace an asset group's listing-group tree

Replace the product (listing-group) tree of a Performance Max retail asset group. The current tree is removed and the new one created in one atomic request. Read the current tree with GET on the asset group. Requires a campaign linked to Merchant Center; other campaigns return 400 LISTING_SOURCE_NOT_ALLOWED from Google. validateOnly: true validates without writing.
