file env (FIREBASE_CREDENTIALS="Project-name-firebase-adminsdk-71slz-90a88a5a5e.json")
file NotificationController

$firebaseApiUrl =
'https://fcm.googleapis.com/v1/projects/ Project ID /messages:send'

and See the display format for sending data in NotificationController

*get GoogleAccessToken = sourceKey
*

Unfortunately, the code is not available using php on the official website, but this is the code using PHP

<?php

namespace App\Services;

use Google\Client;
use Exception;

class GoogleAccessTokenService
{
    protected $client;

    public function __construct()
    {
        $this->client = new Client();
        $serviceAccountPath = base_path(env('FIREBASE_CREDENTIALS'));
        $this->client->setAuthConfig($serviceAccountPath);
        $this->client->addScope('https://www.googleapis.com/auth/firebase.messaging');
    }

    public function getAccessToken()
    {
        $accessToken = $this->client->fetchAccessTokenWithAssertion();

        if (isset($accessToken['access_token'])) {
            return $accessToken['access_token'];
        } else {
            throw new Exception('Failed to get access token');
        }
    }

} // end of GoogleAccessTokenService

It also became a form

$header = [
            'Authorization' => 'Bearer' . $this->googleAccessToken,
            'Content-Type' => 'application/json',
        ];

$payload = [
                    'message' => [
                        'token' => $androidUser->fcm_token,
                        'notification' => [
                            'title' => $title,
                            'body' => $body,
                        ],
                        "android"=> [
                          "priority" => "high",
                          "notification" => [

                          ],
                          "data" => $data // البيانات الإضافية لتطبيق Android

                        ],
                        "apns" => [
                            "headers" => [

                                ]
                            ],
                            "fcm_options" =>  [
                                "image" => "https://foo.bar/pizza-monster.png",
                            ]
                        ],
                        'data' => $data
                    ]
                ];

        $client = new Client(['headers' => $header]);

 $res = $client->post($firebaseApiUrl, [
                    'json' => $payload,
                ]);
