Ad Exchange buyer API overview

The Ad Exchange buyer API allows buyers to build applications that can interact directly with the DoubleClick Ad Exchange platform. With these applications, buyers can more efficiently and creatively manage their large Ad Exchange accounts and campaigns.

The buyer API of DoubleClick Ad Exchange is an adaptation of the AdWords API. If you're interested in using the buyer API, please contact your account manager.

Ad Exchange supports diverse ad buyer business models by providing multiple ways to access and buy impressions, including programmatically. With Ad Exchange, buyers can:

  • Automate actions through the Buyer SOAP API.
  • Automate real-time bidding and manage creatives through the Buyer REST API.
  • Bid for inventory in real time with applications using the Real-Time Bidding (RTB) Protocol.
