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:
POSTScreenshots:
(1)
Note: Always keep your Server Key a secret. Only a portion of my key is visible here so it should be fine.
(2)
(3)
Notice that the request was a success with the message_id in the response.
Postman isn't a resource in the documentation of Firebase... I'm working under windows and there is no cURL built 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 correct?@AL.
{ "to" : "<my token>", "data" : { "body":"Message...", "title":"title..", "score":"880", "time":"02:45" } }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..."
}
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:
I was also getting same error in PHP , solved with below header :
$header = array("authorization: key=" . $this->apiKey . "","content-type: application/json");
