Hi,
We with Assaf are co-workers (well, he is my manager), I think you didn't understand the question correctly (or we don't understand the answer).
In genera, our company provides services to AdWords users via API. Before a customer can start working we ask him to grant us a refresh token (via the OAuth mechanism).
We have a developer token with Standard access, created an application in the developers console and use the Secret of this application to get the refresh token.
XYZ wants to
So far so good. Recently we've developed a report generating tool, for this we only need to read data, without any modification operations. Customers don't trust a product that suggests an analyzing tool, but requests managing permissions.
We would like to change the message from "Manage your AdWords campaigns" to "View your AdWords campaigns".
We Googled it and the only solution that was mentioned is issuing a new developer token with Read-only access level for another Manager. This is a kind of headache (approvals, reviews, regulations etc) and all this just to "downgrade" the approved access level.
What is the best possible way to achieve the goal?
Thanks
