Using the Service You can use the EpayService class in your controllers to handle payments.

Payment Form View The package provides a view for the payment form. You can customize it as needed. The view is located at resources/views/vendor/esewa/payment-form.blade.php.

Defining Routes Define routes in your web.php file for initiating and verifying payments:

php Copy code use App\Http\Controllers\PaymentController;

Route::get('/payment/initiate', [PaymentController::class, 'initiatePayment']); Route::get('/payment/verify/{transactionId}', [PaymentController::class, 'verifyPayment']); Example Controller Create a controller named PaymentController:

php Copy code namespace App\Http\Controllers;

use Sarojsardar\EsewaEpay\EpayService; use Illuminate\Http\Request;

class PaymentController extends Controller { protected $epayService;

public function __construct(EpayService $epayService)
{
    $this->epayService = $epayService;
}

// Method to initiate payment
public function initiatePayment(Request $request)
{
    $amount = $request->input('amount', 100); // Default amount
    $transactionUuid = 'your-transaction-uuid'; // Generate a unique transaction UUID
    $productCode = 'EPAYTEST';
    $successUrl = 'https://your-success-url.com';
    $failureUrl = 'https://your-failure-url.com';

    return $this->epayService->initiatePayment($amount, $transactionUuid, $productCode, $successUrl, $failureUrl);
}

// Method to verify payment
public function verifyPayment($transactionId)
{
    $result = $this->epayService->verifyTransaction($transactionId);
    
    // Handle the result as needed
    return response()->json($result);
}

} Testing the Package To test the package, you can use the following steps:

Run your Laravel application: Start your local server with:

bash Copy code php artisan serve Initiate a payment: Open your browser and navigate to http://localhost:8000/payment/initiate. This should redirect you to the eSewa payment page.

Verify the payment: After completing the payment, you will be redirected to the success URL you specified. You can verify the transaction by calling the verifyPayment method with the transaction ID.
