How do I connect to Google Drive as a web service in Canvas?
The Google Drive web service allows you to integrate Canvas with your Google Drive account. All users can authorize their Google Drive accounts for access to Google Collaborations, and students can upload an assignment from Google Drive.
Note: Canvas currently has two integrations: Google Drive and Google Docs. Only Google Drive needs to be authorized. If Google Docs already exists as a registered service in your account, you will also have to authorize Google Drive.
