About OpenDirect

IAB released the first version of OpenDirect in January 2015. Originally developed by a working group of representatives from AOL, Microsoft, Yahoo, and Yieldex, and later expanded to include executives from Bionic Advertising Systems and MediaMath as well, the OpenDirect specification was brought to IAB and its Digital Advertising Automation Task Force to be part of the trade association’s existing automation efforts, to gain wider industry participation, and to drive adoption across the ecosystem.

Automated Guaranteed is the method of buying which automates the digital direct sale. The deal is negotiated directly between buyer and seller (in-person or via a platform), the inventory and pricing are guaranteed, and the campaign runs at the same priority as other direct deals in the ad server. The RFP (Request for Proposal) and campaign trafficking process are completely automated within the technology platform. OpenDirect is the API specification which supports this process.
