Steps to get Authentication Bearer:

1. Got to Google OAuth Playground: https://developers.google.com/oauthplayground
2. In the "Input your own scopes" for FCM use this url: https://www.googleapis.com/auth/firebase.messaging
3. Tap Authorize API.
4. Pick correct user for authorisation and allow access.
5. In the Step 2: Exchange authorization code for tokens tap Exchange authorisation code for tokens.
6. Access token is your Bearer.

Steps to send FCM throw Postman:

1. URL to send: https://fcm.googleapis.com/v1/projects/projectid-34543/messages:send
2. Request Type: POST
3. Headers: Content-Type -> application/json & Authorization -> Bearer
4. In the body section enter APS payload with the right device token.
5. Click send.

In case you want to use cURL, for a data-notification:

curl --location --request POST 'https://fcm.googleapis.com/v1/projects/your-project-id/messages:send' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer your-access-token-*****-wqewe' \
--data-raw '{
    "message": {
        "token": "device-token-qwfqwee-***-qefwe",
        "data": {
            "Key1": "val1",
            "Key2": "val2"
        }
    }
}'
