The Google Real-time Bidding protocol is deprecated and will sunset on February 15th, 2025. As previously announced , Google plans to no longer send bid requests to endpoints configured to use that protocol after it is sunset.
Additionally, starting September 1st, the protocol will enter maintenance mode, and stop receiving non-critical feature and quality of service updates. If your real-time bidding integration uses the deprecated Authorized Buyers RTB protocol, Google strongly recommends that you start migrating to either our JSON or Protobuf OpenRTB implementations in order to continue accessing the latest real-time bidding features, and avoid interruptions on the sunset date.
You can use the OpenRTB migration guide as a reference while you work on your migrations.
The OpenRTB protocol uses IAB Content 1.0 taxonomy rather than Google’s product and sensitive category IDs when describing categories blocked by publishers with BidRequest.bcat. You can use the new detectedCategories Learn more about changes related to categories.
If you have questions or feedback about how we can ease your migration, please contact us using the Authorized Buyers support forum , or adxbuyerapi-support@google.com .
