When integrating a bidding partner that requires their SDK, the following
symptoms indicate an improper integration:
The
Ad Manager report
shows significantly fewer ad requests to that partner than you expect.
The a3p parameter in any request after the first ad request is missing.
Follow this checklist to make sure your setup is correct:
In the Ad Manager UI:
Confirm that you have followed the specific partner's
integration guide
to configure third-party bidding demand.
Confirm that you have an ad unit mapping for each creative format.
For example, if you're setting up both native and banner, you need an ad
unit mapping for native and another for banner.
