Hi Alex,
Thanks for reaching out to the Google Ads API Forum.
Kindly note that Google Ads API supports performance max report data at campaign level, and not ad group level or ad level. This is working as expected if you’re getting empty data at ad group or ad level reporting. Note that the performance (impressions, cost, clicks, etc) for PERFORMACE_MAX is available using campaign resource. Also, please make sure to not select an AdGroup when querying Performance Max campaigns, as no campaigns will be returned. Let us know if you have any additional questions.
Regards,
