Could you confirm if what you wish to retrieve is the direct equivalent of the Ad Group Performance report in the API, the same as the attached file? If so, you could check out the
Adgroup Performance Report to get statistical reports of your YouTube videos in an adgroup level and use the
AdNetworkType1 and
AdNetworkType2 to filter out only YouTube videos. The other fields specified in your .csv file can also be seen in the link I have provided.
To download reports in the AdWords API, you may follow our
reporting guidelines for further details. You may also refer to our
sample codes on how to download reports.
