title: How to send a silent Push Notification payload
body: <p>I just want to know how I can determine what action to do on a silent push:</p>
  
  <p>This is the <code>aps</code> that I sent to the client:</p>
  
  <pre><code>"aps": {
      "content-available": 1
  }
  </code></pre>
  
  <p>My problem now is when I add <code>type: "Order_Update"</code> to determine that the silent push is for the Order Update to display an alert notification.</p>
