Let’s get started about Laravel 9 Push notification to IOS device using FCM.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Firebase Project and App

First we need to create a project in Firebase console for web application notification. To create project Click here to go to console.

Creating a Firebase Project at Firebase console.

Step #1

Step #2

Step #3

Step #4

Back to Firebase Console dashboard panel. We can see we will have a setup icon for ios device as you can see in this given image. Simply click on that Icon and then the process of Setting up the registration of App will start.

Register a IOS App into Firebase Project.

After creating App from here, back to firebase console. Go to App settings by click on gear icon and Click on Cloud messaging tab. You will find the Server key, we need that.

So copy server key.

Successfully, we have now completed the whole process of

Creating Firebase Project > Register IOS App > Copy & Paste Server API Key.

Add API Route

We need to create a POST request api route which will be hit by IOS device.

Open up the file api.php from /routes folder and add this route into it.

//...

Route::post('send-notification', [App\Http\Controllers\NotificationController::class, 'send']);

Create Controller & Add Method

Next,

To create a controller, we need to run this artisan command:

$ php artisan make:controller NotificationController

After running this command, you will find a controller NotificationController.php file created inside /app/Http/Controllers folder.

Open up the file and write the give code.

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class NotificationController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function send(Request $request)
    {
        return $this->sendNotification($request->device_token, array(
          "title" => "Sample Message", 
          "body" => "This is Test message body"
        ));
    }
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function sendNotification($device_token, $message)
    {
        $SERVER_API_KEY = '<YOUR-SERVER-API-KEY>';
  
        // payload data, it will vary according to requirement
        $data = [
            "to" => $device_token, // for single device id
            "notification" => $message
        ];
        $dataString = json_encode($data);
    
        $headers = [
            'Authorization: key=' . $SERVER_API_KEY,
            'Content-Type: application/json',
        ];
    
        $ch = curl_init();
      
        curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $dataString);
               
        $response = curl_exec($ch);
      
        curl_close($ch);
      
        return $response;
    }
}

The above code will send notification to a single device ID which we will pass into request.

Now,

Let’s say that we want to send notifications to multiple devices.

So how will we send?

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class NotificationController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function send(Request $request)
    {
        return $this->sendNotification(array(
          $request->device_token1, 
          $request->device_token2,
          $request->device_token3
          //..
        ), array(
          "title" => "Sample Message", 
          "body" => "This is Test message body"
        ));
    }
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function sendNotification($device_tokens, $message)
    {
        $SERVER_API_KEY = '<YOUR-SERVER-API-KEY>';
  
        // payload data, it will vary according to requirement
        $data = [
            "registration_ids" => $device_tokens, // for multiple device ids
            "notification" => $message
        ];
        $dataString = json_encode($data);
    
        $headers = [
            'Authorization: key=' . $SERVER_API_KEY,
            'Content-Type: application/json',
        ];
    
        $ch = curl_init();
      
        curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $dataString);
               
        $response = curl_exec($ch);
      
        curl_close($ch);
      
        return $response;
    }
}

Concept

When we send for a single device, we need to use

$data = [
    "to" => $device_token, // for single device id
    "notification" => $message
];

And for multiple devices, we have the key as registration_ids. If we want use this registration_ids to send only to a single device, it also works. Only we need to pass a single device token.

$data = [
    "registration_ids" => $device_tokens, // for multiple device ids
    "notification" => $message
];
