How to Send Firebase Cloud Messaging Notifications Using the REST API?

Sending Firebase Cloud Messaging Notifications via REST API

Firebase Cloud Messaging (FCM) provides server-side APIs for sending notifications without using the Firebase Console. To accomplish this, you can utilize the REST API using cURL.

Steps:

1. Obtain Authorization Token:
   Before making API calls, you need an authorization token. Visit https://firebase.google.com/docs/cloud-messaging/server#authorizing_send_requests to understand the authorization process.
2. Send Message:
   Use cURL to call the FCM HTTP endpoint, specifying the authorization token in the header:

curl -X POST --header "Authorization: key=<API_ACCESS_KEY>" \
    --Header "Content-Type: application/json" \
    https://fcm.googleapis.com/fcm/send \
    -d "{\
        "to":"<YOUR_DEVICE_ID_TOKEN>",\
        "notification":{
            "title":"Hello",
            "body":"Yellow"
        }
    }"

Replace with your actual API key and with the device token you wish to send the notification to.

Other Options:

In addition to the REST API, FCM offers Admin SDKs for various platforms. These specifically built-for-purpose SDKs provide an easier interface for sending notifications from within the respective environments. Here's a list of supported platforms: https://firebase.google.com/docs/cloud-messaging/server#client_sdk_api
