How Can I Send A Firebase Cloud Messaging Notification Without Utilizing The Firebase Console In PHP?

To send a Firebase Cloud Messaging (FCM) notification without using Firebase console, you can use the FCM API with PHP. Follow these steps:

  1. Get the FCM server key:

    • Go to the Firebase console.
    • Select your project.
    • Go to Project settings.
    • Open the Cloud Messaging tab.
    • Copy the Server Key.
  2. Install the php-http/guzzle6-http-client package via composer:
    Open your project directory and run the following command:

    composer require php-http/guzzle6-adapter guzzlehttp/promises guzzlehttp/psr7
  3. Use the following PHP code to send an FCM notification:


require 'vendor/autoload.php';

use GuzzleHttp\Client;
use GuzzleHttp\Psr7\Request;

$serverKey = 'YOUR_SERVER_KEY';
$deviceToken = 'DEVICE_TOKEN';

$message = [
    'notification' => [
        'title' => 'Notification title',
        'body' => 'Notification body',
    'to' => $deviceToken,

$client = new Client([
    'headers' => [
        'Authorization' => 'key=' . $serverKey,
        'Content-Type' => 'application/json',

$request = new Request('POST', '', [], json_encode($message));
$response = $client->send($request);

echo $response->getBody()->getContents();

In the code:

  • Replace 'YOUR_SERVER_KEY' with the server key you obtained from the Firebase console.
  • Replace 'DEVICE_TOKEN' with the FCM token of the specific device you want to send the notification to.

This code sends a POST request to the FCM API endpoint with the necessary headers and message payload. The response will contain the result of the notification sending process.

Make sure you have an FCM token for the device you want to receive the notification. You can get the token in your Android or iOS application by implementing the FCM token retrieval logic.

Additionally, you may need to handle error cases and implement a more sophisticated error/exception handling mechanism.
