To align more closely with industry practices and embrace OpenRTB as the standard protocol,
Authorized Buyers Real-time Bidding protocol will sunset February 15th, 2025. Following this date, bid requests will no longer be sent to endpoints configured to use the Authorized Buyers RTB protocol . After this time we will support the OpenRTB protocol only. We strongly recommend that you transition to either the JSON or Protobuf formats of the Authorized Buyers OpenRTB protocol implementation as early as possible to avoid interruptions to your bidding integration.
As a first step in migrating to OpenRTB, we suggest that you read through the OpenRTB migration guide . The guide highlights differences between the Google RTB protocol and the supported OpenRTB formats, identifies how Google RTB protocol fields map to OpenRTB, and provides instructions for complex mappings. We will continue updating our developer content as we approach February 2025 to provide additional guidance, and to ensure a smooth migration.
For any questions or feedback you have concerning the transition to OpenRTB, please contact us using the Authorized Buyers support forum , or adxbuyerapi-support@google.com .
