Hi Nathan,
In order to confirm exactly what you are looking for, can you please provide screenshots of the UI so that I can check if it is supported in the API? Additionally, metrics such as ad requests sent, responses served, and unmatched ad requests are available in
ReportQuery as TOTAL_AD_REQUESTS, TOTAL_RESPONSES_SERVED, and TOTAL_UNMATCHED_AD_REQUESTS, respectively. Let me know if this is what you are looking for.
Thanks,
Danica Calusin, Ad Manager API Team
