        "extra_information": "This is some extra information"
    },

//notification that i need to give

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..."
}

$header = array("authorization: key=" .  $this->apiKey . "","content-type: application/json");

While the answers above are still correct, you may choose to use HTTP v1. This requires Bearer instead of key= and uses an Oauth2 access token instead of a server key string. To view HTTP v1 specifications, please refer to the link below:

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:
  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.

(2) enter image description here

(3) enter image description here

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