title: How to register devices to Azure Notification Hub from server side(with NodeJS sdk) ?
body: <p>I am developing a windows phone 8.1 App (RT), I am trying to push notification with Azure Notification Hub. I am able to do it with the client side SDK available. But I want to do the device registration, tagging etc. from the server side. I see a good guide for .Net backend at <a href="http://blogs.msdn.com/b/azuremobile/archive/2014/04/08/push-notifications-using-notification-hub-and-net-backend.aspx">http://blogs.msdn.com/b/azuremobile/archive/2014/04/08/push-notifications-using-notification-hub-and-net-backend.aspx</a> . I am using NodeJS in the backend server side. Can anyone help me in the same, with a sample code or so. </p>
  
  <ul>
  <li>I want to register devices from server side (iPhone, Android &amp; Windows Phone), actually I have the device tokens available at the servicer side which is sent from the device via API call. </li>
  <li>I want to update multiple tags for each devices time to time. </li>
  <li>I want to unregister the devices when user request to do so. </li>
  <li>I want to send push notification to specific tags, using the template. </li>
  </ul>
