Relay Overview

What Is Relay?

Kevel’s Relay APIs help you manage your ad server and demand partners by acting as a layer between these two components, enabling you to more precisely control which advertisers “win,” and why.

This section introduces you to Relay by providing conceptual information and a system overview, in addition to detailed descriptions of the individual components that make up Relay.

Detailed use cases and scenarios are also provided, enabling you to properly leverage Relay for your own business workflows, including:

  • How to use the OpenRTB exchange to make outbound OpenRTB requests from a single input request.
  • How to use the Configuration API to set up and manage data the OpenRTB Exchange uses.



The Configuration API is currently in its early stages of development and under frequent iteration. If you require a more stable version of an API for development, please use the Exchange API instead.
