Update a Performance Max asset group

Change the name, status (ENABLED or PAUSED), final URLs or display paths. Only the fields sent are written; null on path1 or path2 clears it. Change assets with the /assets endpoint and product targeting with /listing-group-filters. validateOnly: true validates without writing.

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.
