title: What should the OAuth2 redirect_uri be for a desktop (non-web) application?
body: <p>I'm writing an application that will integrate a web application (i.e. Harvest).  The web application supports authorization via <code>OAuth2</code>.</p>
  
  <p>The workflow seems to be:</p>
  
  <ol>
  <li><p>Direct the user to a specific URL where they can be authenticated and give permission to my application.  </p></li>
  <li><p>Within that first request, I'm supposed to provide a <em>callback uri</em> that will receive the authorization token.</p></li>
  <li><p>Use the sent authorization token to make requests on behalf of the user.</p></li>
  </ol>
  
  <p>The first part seems simple enough, but what should the <em>callback uri</em> be?  This isn't a website, it doesn't have an exposed web interface.</p>
