title: Google Drive File Download URL
body: <p>Is the only way to download a file through Google Drive through the download_url that is provided?  I have the file_id and would like to make one simple call to download the file.  Right now it looks like you have to make one call to fetch the file metadata and retrieve the download_url, then another to actually download the file.  Is this the only way?</p>
  
  <p>Also, the download_url is described as a "short lived url".  How long will this url be available for?</p>
  
  <p>Thanks</p>
