Bidding and Auction (B&A) Services Browser API availability will ramp up to 100% of Chrome Stable channel users from Nov 13 onwards. The full ramp up to 100% availability will take about 2 weeks once released.
This release won't affect your B&A implementation code, such as your joinAdInterestGroup() and runAdAuction() call. Your integration with existing or new ad tech platforms won’t be affected either. However, we encourage ad tech companies who have adopted B&A to review their configurations to control traffic for this expanded reach. DSP should control their traffic intake by coordinating with their SSPs.
