Frequently Asked Questions

What version of OpenRTB is supported?

This validator currently supports OpenRTB 2.5, which is the most widely adopted version in the industry.

What are the required fields in an OpenRTB bid request?

The most critical fields are id, imp (array with at least one element), and either site or app. Each imp must have a banner, video, audio, or native object.

How do I fix "both site and app present"?

A bid request represents traffic from either a website or a mobile app. Including both is a violation of the spec. Remove the object that does not apply to the traffic source.
