I'm working on building a new tool for my customers that helps automate their ads and see daily / weekly reports and improvements. However, I'm having a humbling issue with the Google Ads API. I've set up a manager account, and my clients have given me access. However, it won't let me see their clicks. Google has ever so delicately told me that my manager account will not let me see their clicks within the API. I can see them in my dashboard. But I can't call them with my API. Am I not supposed to build a good report for my customers? Any query through manual requests on AWQL results the same. I don't know why I can't get their clicks/performance. Google's told me, "It's not me. It's you."
I have my Google Dev token. My own Oauth2 on my manager account. I thought the purpose of the manager account was so I could have the API. Have been reading for hours, but I'm missing something simple. What should I be requesting / authenticating with to get the clicks for my clients?
