Edit a Google campaign's device, location, or language targeting

Google Ads compliance row M.10: geo and language targeting set at creation must stay editable afterwards. Send at least one of `devices`, `locations`, `languages`; each provided field REPLACES that field's existing criteria on the campaign (a full set, not a delta). Fields left out of the body are untouched. Google only; every other platform returns 501. `locations` accepts the same shapes as campaign creation: a bare array of ISO country codes, or an object with `countries`/`regions`/`cities`/`zips`/`metros` key lists (`key` from GET /v1/ads/targeting/search?dimension=geo). Negative (excluded) locations are left untouched by this endpoint. `languages` is an array of Google's language codes (ISO 639-1, plus variants such as `zh_CN`); an unknown code returns 400. The response includes the refreshed `devices`/`locations`/`languages` state read back from Google after the edit, and invalidates the cached copy `GET` on this campaign would otherwise keep serving.

List Meta product catalogs

Lists the Meta product catalogs reachable from an ad account (owned + agency-shared catalogs of the ad account's business), for Advantage+ catalog ads (`goal: catalog_sales` on POST /v1/ads/create, e.g. vehicle inventory catalogs). Read-only; uses scopes customers already granted (no reconnect needed). Catalog contents (items, feeds) are managed in Meta Commerce Manager, not through this API.
