Hi,
Thank you for reaching out to us. I see that you'd like to pull campaign data from account
605-851-1694 via Google Ads API. I took a look at your account and saw that the account
605-851-1694 is in fact a manager account. Manager accounts cannot provide you with data on campaigns because a manager account only handles customer accounts, and customer accounts handle campaigns. Because of this, you will have to make a separate call to each of the customer accounts that you'd like to get campaign information from. Let me know if you have further questions.
Thank you,
Bryan, Google Ads API Team
