I am trying to Create a Client test account under Test manager account of google ads API but my test manager account is marked as closed. See below
As mentioned in the picture a, we need to use new google account to create test manager account that is not been used in production manager account, I did the same. I created new google account and created test manager account but when I try to generate Refresh token for test account by using OAuth playground, It generates an error. see picture b.
Picture b.
Am I doing something wrong to configure the test manager account? Is there anything I need to follow to enable test account? The request to generate refresh token is getting denied. Is it because my account is closed?
