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.

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.

List ad sets

Ad sets (Google ad groups) synced for the connection, optionally filtered by platform and campaignId. Reads the `ad_sets` table directly, independent of the `ads` rollup GET /v1/ads/tree uses, so a newly created standalone ad group with no ad yet (POST /v1/ads/ad-sets, Google only) is visible here even though it is invisible in the tree until an ad joins it via `adSetId` on POST /v1/ads/create. Returns at most 500 rows, newest first. **Status freshness.** `status`, `configuredStatus`, `platformStatus`, `platformAdSetStatus` and `platformCampaignStatus` are the values Zernio last stored. Background sync refreshes them, typically within 15 to 60 minutes (Google up to about 3 hours), and ended or long-paused objects may be refreshed less often. Zernio's own status writes re-read the switches they change. A change made in the platform's own ads manager therefore shows up here only after the next sync. Controllers that act on a switch should pass `live=true`, which reads the switches from the platform now, stores them, and returns `statusReadAt` (null when the read failed and the stored values were returned). With `live=true` (which needs a `campaignId` or `adSetId` filter) each listed ad set's own switch (`platformAdSetStatus`) is read live, for the first 20 rows; later rows keep their synced value with `statusReadAt: null`. Live reads cover TikTok, Meta, Google and OpenAI. The rolled-up `status` is not re-derived by a live read. On TikTok the same live read also returns the ad group's applied `optimizationGoal` and `billingEvent`, as TikTok's adgroup/get reports them, so you can verify the goal TikTok applied rather than the one you requested. It also returns `nativeSettings`: TikTok's own adgroup/get record for the ad group, verbatim and read in that same call (budget, budget_mode, schedule, placements, locations, ages, gender, languages, interests, actions, audiences and exclusions), plus the advertiser's currency and timezone. TikTok's `schedule_start_time` / `schedule_end_time` are UTC wall clocks ("YYYY-MM-DD HH:MM:SS", no offset); Ads Manager displays them in `advertiser_timezone`. `configReadAt` says when it was read; it is null on every row whose native settings were not read now, so never treat a null as a match. These are read, not retained create payloads, and are not stored.
