• API credentials from Meezan Bank
• A Laravel application (Laravel 9 or 10 recommended)
• Basic knowledge of REST APIs and Laravel development

Step-by-Step Guide to Meezan Payment Gateway Integration in Laravel

Step 1: Obtain API Credentials

First, register as a merchant with Meezan Bank and obtain the API key, secret key, and endpoint URLs.

Step 2: Install Required Laravel Packages

Ensure your Laravel project is set up and installed guzzlehttp/guzzle to handle API requests:

composer require guzzlehttp/guzzle

Step 3: Configure API Credentials

Add your Meezan Bank API credentials to the .env file:

MEEZAN_API_KEY=your_api_key_here
MEEZAN_SECRET_KEY=your_secret_key_here
MEEZAN_ENDPOINT=https://sandbox.meezanbank.com/api/payment

Then, update config/services.php:

return [
    'meezan' => [
        'key' => env('MEEZAN_API_KEY'),
        'secret' => env('MEEZAN_SECRET_KEY'),
        'endpoint' => env('MEEZAN_ENDPOINT'),
    ],
];

Step 4: Create a Payment Controller

Generate a Laravel controller to handle payment requests:

php artisan make:controller PaymentController

Inside,PaymentController.php add the following:

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use GuzzleHttp\Client;

class PaymentController extends Controller
{
    public function initiatePayment(Request $request)
    {
        $client = new Client();
        $response = $client->post(config('services.meezan.endpoint'), [
            'headers' => [
                'Authorization' => 'Bearer ' . config('services.meezan.key'),
                'Content-Type' => 'application/json'
            ],
            'json' => [
                'amount' => $request->amount,
                'currency' => 'PKR',
                'callback_url' => route('payment.callback'),
                'order_id' => uniqid(),
            ]
        ]);

        $data = json_decode($response->getBody(), true);
        return redirect()->to($data['payment_url']);
    }
}

Step 5: Define Routes in Laravel

Open routes/web.php and add:

use App\Http\Controllers\PaymentController;

Route::post('/pay', [PaymentController::class, 'initiatePayment'])->name('payment.initiate');
Route::get('/payment/callback', function () {
    return 'Payment Successful!';
})->name('payment.callback');

Step 6: Create a Payment Form

In your Blade template, create a simple payment form:

<form action="{{ route('payment.initiate') }}" method="POST">
    @csrf
    <label>Enter Amount:</label>
    <input type="number" name="amount" required>
    <button type="submit">Pay Now</button>
</form>

Step 7: Handle Payment Response

Once the payment is processed, Meezan Bank will redirect the user to the callback URL with a response status. You can handle success/failure messages accordingly.
