I work for an agency and I need to add the agency analytics google account to a client's YouTube channel so the agency account can see the YouTube channel and specifically access its analytics. How do I do that?I have added the agency account as a manager to the YouTube / Google+ account of the client but when I try to use Google Script to call the YouTubeAnalytics.Reports.query('channel==clientChannel',....) method. I receive a Forbidden error even though when I click through to the client channel I can look at the analytics page.
