title: Allowing a third party website to save to my drive (and with no sharing permission)
body: <p>We're working on an app to sell our music and was wondering if Google Drive can be used as an online storage solution.</p>
  
  <p>The user would complete the transaction on our site, and then authorize us to save the file (or multiple files) to their Google Drive.</p>
  
  <p>The appeal to us is to solve downloading problems via the browser. I believe the Google Drive api returns a successful response when the delivery is complete. If incomplete, we would then either resend or update.</p>
  
  <p>One other requirement is whether we can set permissions to not allow sharing after save (and for that setting to be permanent).</p>
