OpenRTB DSP Integration Guide

Table of contents

General Info

The Adskeeper SSP platform supports protocol OpenRTB 2.5 banner, native 1.1, native 1.2 and video.

When an impression is available for bidding within the Adskeeper network, a bid request is sent to each DSP. All bid requests are only HTTP POST requests that pass the data in a JSON object (we currently only support JSON encoded bid requests). Bid requests will be sent to the DSP via HTTP to a URL specified by the DSP.
