How to get registration key Firebase?

Question

Firebase allows us to send notification messages via our own application by making POST request.

This tutorial gives instructions how to make this request. However, there is a "to" field in the JSON, where I must place a Registration key.

Where can I get this Registration key? There are no instructions for this.

Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

{
  "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
  "data" : {
    ...
  },
}

I guess the Firebase crew isn't answering questions anymore. I also have this question. The documentation is inadequate. — rm.rf.etc

To get a token, call FirebaseInstanceId.getInstance().getToken();. After that step, in order to see the token, just make an output to Logcat

Code example:

String token = FirebaseInstanceId.getInstance().getToken();
Log.i("MainActivity", "Token: " + token);
