title: REST API for Sharepoint to get subsite users
body: <p>All I want to do is get a list of users <strong>allowed to access a specific <em>subsite</em></strong> in SharePoint using the <strong>REST API</strong> only. Just a single HTTP GET like such:</p>
  
  <p><code>http://&lt;site url&gt;/_api/Web/SiteUsers</code></p>
  
  <p>Yes, I know that the above referenced call will give me ALL USERS allowed to access ANY SharePoint site and that is not what I want or need, it is only an example.</p>
