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..."
}

I was also getting same error in PHP , solved with below header :

$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.

(3) enter image description here

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

Thank you @AL. you saved my tons of recherche to read! It's a pitty that Postman isn't a resource in the documentation of Firebase... I'm working under windows and there is no cURL built in!

@AL. 2018-02-13 11:35:26

@webprogrammer You're welcome. :) Actually, the instructions I made used to be in the StackOverflow documentation, but the service closed a few months ago. I guess there are a lot of options available and Firebase doesn't want to seem like they're being biased with a service. Cheers!

After sending notification from firebase console, if the app is not in foreground it won't receive in onMessageReceived method of MyFirebaseMessagingService.java class. Tapping that notification, It will take us to launcher activity. From there we have to call this https://fcm.googleapis.com/fcm/send url using retrofit, passing what data we have received in launcher activity. And after that response will hit the onMessageReceived method of MyFirebaseMessagingService.java class. Is it [email protected]

@AL. get message_id but not created in fcm notification history and also not received notification

@Sudhanshu Gaur 2018-09-27 17:53:39

Hi, Can you please look at my question regarding firebase stackoverflow.com/questions/52523615/…

@rotoxl 2018-11-12 11:57:56

Hi! I also didn't receive the message but found out that changing the body message on screenshot 2 the push arrived to the phone { "to" : "<my token>", "data" : { "body":"Message...", "title":"title..", "score":"880", "time":"02:45" } }
