I\'m trying to use the Google file picker to select a document and then update its permissions. I don\'t need access to all Drive files, just those selected.
Howeve
If you're modifying a file that's not created by your application, there is no more restricted scope other than the drive
scope.
Answering my own question thanks to help from folks on the Google Drive Developer discussion on Google Plus:
This does work. I was using the wrong App_ID in my picker implementation - I needed to use only the numeric string at the beginning of the client ID. The other problem, it doesn't work on localhost, only in production.
