Answer 1

Based on the error you are getting...

https://developers.google.com/drive/v3/web/manage-downloads

Try adding "?alt=media" to your GET request. My guess is you are missing something in the input parameters or possibly do not have access to the media (not logged in maybe?). I can't help more without seeing the actual code you are attempting to call, or the request you are making.
