The 401 error pertains that your Authorization Key is invalid or incorrect.

When using Postman, add a key= prefix for the value of Authorization, like so:

key=AAA... 

See below for a tutorial on Sending Downstream FCM Messages using Postman.

Also, for your notification message payload, text isn't one of the valid parameters, I think you were looking for message instead.



Sending Downstream Messages using Postman

To do this in Postman, you simply have to set the following:

  1. Set request type to POST
  2. In the Headers, set the following:
    • Content-Type = application/json
    • Authorization = < Your FCM Server Key > (See your Firebase Console's Cloud Messaging Tab)
  3. Set the payload parameters in the Body (*in this example, we used the raw option, see screenshot (2)*)
  4. Send the request to https://fcm.googleapis.com/fcm/send

Screenshots:

Note: Always keep your Server Key a secret. Only a portion of my key is visible here so it should be fine.

Notice that the request was a success with the message_id in the response.

Wrong:

Authorization:AIzaSyDDk77PRpvfhh......

Correct:

Authorization:key=AIzaSyDDk77PRpvfhh......

Full example:

https://fcm.googleapis.com/fcm/send Content-Type:application/json Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA  { "data": {     "score": "5x1",     "time": "15:10"   },   "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..." }
