Firebase : Send notification with REST API

Question

Is it possible to send push notification with REST API on Firebase? I can send notifications with Firebase console but i need to send notifications with REST API.

Answer 1

Just for helping,

If anyone wants to use REST POST API, here it is, use the Postman with below configuration

URL:
https://fcm.googleapis.com/fcm/send

Header:

"Content-Type": "application/json",
"Authorization": "key=<Server_key>"

BODY:

{
    "to": "<Device FCM token>",
    "notification": {
      "title": "Check this Mobile (title)",
      "body": "Rich Notification testing (body)",
      "mutable_content": true,
      "sound": "Tri-tone"
      },

   "data": {
    "url": "<url of media image>",
    "dl": "<deeplink action on tap of notification>"
      }
}

That's it. Thanks!!!

Answer 2

I used the below rest API to send notification.

curl -X POST \
  https://fcm.googleapis.com/fcm/send \
  -H 'Authorization: key=AAAAG-oB4hk:APA91bFUilE6XqGzlqtr-M-LRl1JisWgEaSDfMZfHuJq3fs7IuvwhjoGM50i0YgU_qayJA8FKk15Uvkuo7SQtQlVt4qdcrrhvnfZyk_8zRGAskzalFUjr2nA2P_2QYNTfK6X8GbY0rni' \
  -H 'Content-Type: application/json' \
  -H 'Postman-Token: c8af5355-dbf2-4762-9b37-a6b89484cf07' \
  -H 'cache-control: no-cache' \
  -d '{
    "to": "ey_Bl_xs-8o:APA91bERoA5mXVfkzvV6I1I8r1rDXzPjq610twte8SUpsKyCuiz3itcIBgJ7MyGRkjmymhfsceYDV9Ck-__ObFbf0Guy-P_Pa5110vS0Z6cXBH2ThnnPVCg-img4lAEDfRE5I9gd849d",
    "data":{
        "body":"Test Notification !!!",
        "title":"Test Title !!!"
    }

}'

Authorization : key=AAAAG-oB4hk:APA91bFUilE6XqGzlqtr-M-LRl1JisWgEaSDfMZfHuJq3fs7IuvwhjoGM50i0YgU_qayJA8FKk15Uvkuo7SQtQlVt4qdcrrhvnfZyk_8zRGAskzalFUjr2nA2P_2QYNTfK6X8GbY0rni

where key is web_server_key from the console and you need to specify the unique registration key which you will get from the app.

"to": "ey_Bl_xs-8o:APA91bERoA5mXVfkzvV6I1I8r1rDXzPjq610twte8SUpsKyCuiz3itcIBgJ7MyGRkjmymhfsceYDV9Ck-__ObFbf0Guy-P_Pa5110vS0Z6cXBH2ThnnPVCg-img4lAEDfRE5I9gd849d" is the FCM registration token from device. Please refer to the below link.
