The Ad Exchange Buyer II API is now deprecated, and the following resources will be sunset on September 29th, 2023:

• accounts.clients
• accounts.clients.invitations
• accounts.clients.users
• accounts.creatives
• accounts.creatives.dealAssociations
• accounts.finalizedProposals
• accounts.products
• accounts.proposals
• accounts.publisherProfiles

Accessing the sunset resources will return an error response following the sunset date. Note that RTB Troubleshooting resources aren’t included in this list, and will continue to be supported until further notice.

To continue programmatically accessing your Client Access and Marketplace configurations, you should migrate to the Authorized Buyers Marketplace API. For more information, we recommend that you review the Marketplace guide and samples. If you have any questions or feedback, feel free to reach out to us via the Authorized Buyers API Forum.

The Authorized Buyers Marketplace API has been released. You can use the Marketplace API to manage clients, users, and auction packages, and to negotiate proposals with publishers. This new API is intended to replace the following Marketplace resources included in the Ad Exchange Buyer II API:

• accounts.clients
• accounts.clients.invitations
• accounts.clients.users
• accounts.finalizedProposals
• accounts.proposals
• accounts.publisherProfiles

Although the Ad Exchange Buyer II API is not deprecated at this time, we recommend that all Marketplace integrations adopt the new API to receive the latest updates going forward. New features will only appear in the Marketplace API.

The Marketplace API introduces the following features:

• Programmatic support for auction packages.
• Deals are now a sub-resource of proposals.
• The finalizedDeals resource helps you manage deals.
• The rtbMetrics field of finalizedDeals provides performance data.

Given that the Marketplace API is distinct from the existing Real-time Bidding and Ad Exchange Buyer II APIs, please note that you need to enable the Authorized Buyers Marketplace API in your Google Cloud Console project. Additionally, you need to update your existing OAuth 2.0 credentials and workflows to include a new API scope:

https://www.googleapis.com/auth/authorized-buyers-marketplace

For any questions or feedback about this API, please contact us via our support forums.
