For the new FCM HTTP v1 API, the method of testing push notifications through Postman has changed and the existing solutions only addressed the legacy method of testing push notifications: https://firebase.google.com/docs/cloud-messaging/send-message

To test on Postman with FCM HTTP v1 API, you will need to first fetch a short-lived Oauth 2 token. You can generate one as per the information on the Firebase site here: https://firebase.google.com/docs/cloud-messaging/auth-server

I generated mine using Python using the code below - remember to pip install the package so that you can import the package into your code successfully:

from oauth2client.service_account import ServiceAccountCredentials

def _get_access_token():
  """Retrieve a valid access token that can be used to authorize requests.

  :return: Access token.
  """
  credentials = ServiceAccountCredentials.from_json_keyfile_name(
      'service-account.json', FCM_SCOPE)
  access_token_info = credentials.get_access_token()
  return access_token_info.access_token

Once you have the token - you can insert it into your Postman under authorisation:

IMPORTANT:

In my case, I had struggled a bit to get this to work as I was trying to test a scheduled task that was going to send push notification every few minutes to FCM. I had printed the token to my logs and then taken that token to my Postman for testing, not realising that it already has been used in the scheduled calls to FCM.

In that case, because it has already been used, the token will no longer be valid and my Postman tests were all failing. In this case, you will need to generate fresh tokens for your Postman tests.

Have you check this : Test FCM Notification with POSTMAN!

Send Data Message using HTTP protocol with POSTMAN

• You have to copy Legecy Server Key from Firebase Console > Project Settings > Cloud Messaging

Note: Firebase has upgraded our server keys to a new version. You may continue to use your Legacy server key, but it is recommended that you upgrade to the newest version.

• Select POST. Enter request URL as https://fcm.googleapis.com/fcm/send

• Add Headers Authorization: key=<legacy_server_key> OR Authorization: key=<server_key> and Content-Type: application/json.

• Now Select Body > raw > JSON (application/json) and add following code:

    {
         "to" : "YOUR_FCM_TOKEN_WILL_BE_HERE",
         "collapse_key" : "type_a",
         "notification" : {
             "body" : "Body of Your Notification",
             "title": "Title of Your Notification"
         },
         "data" : {
             "body" : "Body of Your Notification in Data",
             "title": "Title of Your Notification in Title",
             "key_1" : "Value for key_1",
             "key_2" : "Value for key_2"
         }
    }

I have created POSTMAN Collection for you, Run in Postman directly.

Hope it will helps you.

Answer 6

What exactly is Server Key? I used (on a pitcure above) server key, and legacy server key but neither of them work.

Does anybody have clue what is wrong? For token -> I used FCM token I got from firebase messaging like this:

firestoreMessaging.getToken()
