I'm working on a page that will be available to certain users where they can see shared Google Analytics data. I want to pull the data with JavaScript and I've succeeded in getting an OAuth token for the account with the GA data, but it expires in 1 hour.
How can I use this token for all users coming to the page? I don't need the users to be able to access their own GA data, just the shared data. Is there a way to make the token permanent or to refresh it?
