Migrate to the OpenRTB protocol

Google will migrate from Google Authorized Buyers protocol to the OpenRTB protocol on 2/15/2025 to align more closely with industry standards. This should ultimately reduce integration friction and maintenance complexity. We are providing this migration guide to assist you with transitioning to the OpenRTB protocol.

This guide consists of the following:

Mapping Guide

Visit the developer site for the full mapping guide. If you have feedback, visit the Technical Support section or share your feedback with your account manager.

Experimentation

Google can set up an A/B experiment to test the performance between an OpenRTB endpoint and a Google Protocol endpoint. Reporting will be available through a cloud bucket. Contact your account manager if you’re interested in setting up an A/B experiment or have any questions.

Technical Support

For technical support or questions about the process, here are some options:

  • Your Technical Account Manager can help with account configuration, product and UI questions, and some technical support. If you don’t have an assigned point of contact, use the contact form.
  • Access Contact Us if you don’t have an assigned Technical Account Manager for account configuration.
  • Authorized Buyers support forum provides public answers about the RTB protocols or APIs. You can search for similar  questions to find answers to your questions. 
  • Use the Technical API email support for answers to private questions about the RTB protocols or APIs. Unlike the support forum, questions here are private and can include details about your account that may assist with investigating your question or issue.
