title: Save notification in console on use REST API
body: <p>I'm using Firebase to send notification to devices. I'm following the specification of <a href="https://firebase.google.com/docs/cloud-messaging/server" rel="nofollow noreferrer">REST API</a> as describe in firebase website. Everything is working fine. </p>
  
  <p>I would like to know if it is possible to keep a copy of sent message in the console even sending them form REST API.</p>
  
  <p>Taking a look in <a href="https://firebase.google.com/docs/cloud-messaging/http-server-ref#table1" rel="nofollow noreferrer">server reference</a>, I didn't find anything related with this. Actually is not a requirement, its only personal curiosity.</p>
