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

We used the following documentation to send notifications from a web client.

There is an easy way to send a notification via Chrome App or Extension.

function sendMessage() {
  var message = {
    messageId: getMessageId(),
    destinationId: senderId + "@gcm.googleapis.com",
    timeToLive: 86400,    // 1 day
    data: {
      "key1": "value1",
      "key2": "value2"
    }
  };
  chrome.gcm.send(message, function(messageId) {
    if (chrome.runtime.lastError) {
      // Some error occurred. Fail gracefully or try to send
      // again.
      return;
    }

this may help - https://firebase.google.com/docs/cloud-messaging/http-server-ref where sample message you can find here - https://firebase.google.com/docs/cloud-messaging/downstream

from Firebase console you can get Server Key as an authorization you put in the http header, in the tab Cloud messaging.

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.

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!!!

Using ARC For Sending Request to Firebase Console To Send Notification

You can use ARC OR Postman or your own server to send notification. You need to collect your web_server_key from the console and you need to specify the unique registration key which you will get from the app when calling the onRefreshToken() method.

You need to send the request to https://fcm.googleapis.com/fcm/send with Content-Type : json and Authorization: web_server_key. On To value user your app_registration_token .
