Each page below documents a single buyer-routing operation — request, parameters, response shape, and errors. These endpoints apply only to Google Ad Manager-backed embedded sales agents (ESAs): a default advertiser catches all unmatched buyers, and per-buyer mappings override it. For the conceptual model, see the Buyer routing overview.
