openrtb.2.6.bid.apis

What it means

OpenRTB 2.6-202204 introduced bid.apis, which openRTB 2.6 added the multi-valued bid.apis field..

Why it matters

bid.apis is only defined from 2.6-202204 onward. Used against an earlier version it is not valid, and a consumer below 2.6-202204 treats it as an unknown field.

How to fix it

Target OpenRTB 2.6-202204 or later when you send bid.apis, and make sure the value matches the type and any enum the specification defines for it.

Paste your bid request into the tester and select OpenRTB 2.6-202204 to see whether this rule fires against your payload.
