Get a Performance Max asset group

One asset group with its linked assets, ad strength, primary status and listing-group tree. Uses a 10-minute cache, served stale when Google quota is exhausted; any write below clears it.

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.
