Update a Google Ads portfolio bid strategy

Renames or retargets a portfolio bid strategy. The strategy's status is output only on Google's side, so it cannot be changed here; remove a strategy in Google Ads. `type` is only needed alongside `targetCpa`/`targetRoas` to disambiguate the field Google writes to (TARGET_CPA and MAXIMIZE_CONVERSIONS both take a target CPA; TARGET_ROAS and MAXIMIZE_CONVERSION_VALUE both take a target ROAS); the strategy's family is otherwise immutable once created.

List a catalog's product sets

Lists a Meta product catalog's product sets, the unit a catalog ad promotes. Pass the chosen set id, not the parent catalog id, as `promotedObject.productSetId` on POST /v1/ads/create with `goal: catalog_sales`. Creation verifies set visibility and returns 400 for a catalog id or an inaccessible set.
