Hi Theo,
Thank you for following up. Our team was able to receive your private reply and we've already sent replies there. Unfortunately, it appears that you are not receiving our replies. With this, I would like to reiterate my reply and you can see it below.
I can see that you are comparing the campaign view of the UI and
ad_group report type, unfortunately, this is not the correct mapping of API report in the UI.
If you want to get the data at the campaign level, then you need to use the
campaign report instead. Otherwise, if you want to compare the data of
ad_group report in the UI, then the correct mapping of this report is discussed
here.
Furthermore, please ensure that you are using the same fields, filters and date ranges in the API report and UI when comparing the data to each other.
Regards,
