Hi Giuseppe,
Thank you for posting your concern.
The reason why you can't retrieve the information of the Performance Max is because this type of campaign is not supported in AdWords API. With this, I would suggest to
migrate to the Google Ads API as it supports more types of entities like Performance Max campaign. The other reason why I suggested to migrate to the Google Ads API is because the AdWords API is deprecated and
will be sunset on April 27, 2022.
Let me know if you have further questions.
Regards,
