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.

Create a Performance Max asset group

Add an asset group to an existing Performance Max campaign. The group, any new assets, their links and an optional listing-group tree are created in one atomic request, so Google checks the asset minimums (for non-retail campaigns) against the whole set. Created PAUSED unless status is ENABLED. validateOnly: true runs Google's validation without creating anything.

Get live campaign details

Reads one campaign live from Meta, returned verbatim, so a caller that knows a campaign id no longer has to page `GET /v1/ads/campaigns` to find it. The default projection covers name, status, objective, buying type, bid strategy, budgets, spend cap, schedule and `issues_info`. `fields` is a raw-passthrough override; unknown fields return Meta's 400 verbatim. A campaign the resolved connection cannot see comes back as Meta's own 400, not a 404.
