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");
