Create Payment Link On PayU Money Payment Gateway In Laravel 11

Introduction

PayU Money is a popular payment gateway that allows businesses to accept online payments seamlessly. In this guide, we will demonstrate how to create a payment link using PayU Money in a Laravel application.

Prerequisites

Before proceeding, ensure you have the following:

• A Laravel project set up
• PayU Money account with API credentials
• Composer installed.

Step 1: Define the Route

In routes/web.php, add the following route to handle payment link generation:

use App\Http\Controllers\PayUController;
use Illuminate\Support\Facades\Route;

Route::post('/payu/payment-link', [PayUController::class, 'generatePaymentLink']);

This route is responsible for processing the payment link request.

Step 2: Create the PayU Controller

Inside app/Http/Controllers/PayUController.php, create the PayUController with the following code:

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Log;
use GuzzleHttp\Client;

class PayUController extends Controller
{
    public function generatePaymentLink(Request $request)
    {
        $token = $this->getAuthToken();
        
        if (!$token) {
            Log::error('PayU Auth Token missing');
            return response()->json(['success' => false, 'error' => 'Auth token missing'], 500);
        }

        try {
            $payload = json_encode([
                "source" => "API",
                "subAmount" => $request->amount, // Payment Link Amount.
                "currency" => "INR",
                "description" => $request->description, // Payment Link Title.
                "customer" => [
                    "name" => $request->name, // Payment Client Name.
                    "email" => $request->email, // Payment Client Email.
                    "phone" => $request->phone // Payment Client Phone Number.
                ]
            ]);
        
            $response = (new Client())->post("https://oneapi.payu.in/payment-links", [
                'headers' => ['Authorization' => "Bearer $token", 
                              'Content-Type' => 'application/json', 
                              'merchantId' => 'YOUR_MERCHANT_ID'], 
                              'body' => $payload]);
        
            $responseData = json_decode($response->getBody(), true);
            return response()->json([
                'success' => true,
                'payment_url' => $responseData['result']['paymentLink'] ?? '',
                'payment_data' => $responseData
            ]);
            
        } catch (\Exception $e) {
            return response()->json(['success' => false, 'error' => $e->getMessage()], 500);
        }
    }

    public function getAuthToken()
    {
        try {
            $response = (new Client())->post("https://accounts.payu.in/oauth/token", [
                'headers' => ['accept' => 'application/json',
                              'content-type' => 'application/x-www-form-urlencoded'],
                'form_params' => [
                    'grant_type' => 'client_credentials',
                    'client_id' => "YOUR_CLIENT_ID",
                    'client_secret' => "YOUR_CLIENT_SECRET",
                    'scope' => 'create_payment_links',
                ]]);
        
            $data = json_decode($response->getBody(), true);
            if (empty($data['access_token'])) throw new \Exception('Access token not received');
        
            return $data['access_token'];
        } catch (\Exception $e) {
            return response()->json(['success' => false, 'error' => $e->getMessage()], 500);
        }
    }
}

Replace YOUR_CLIENT_ID, YOUR_CLIENT_SECRET, and YOUR_MERCHANT_ID with your actual PayU credentials.

Step 3: Create the Blade Template

In your resources/views/ directory, create a Blade template for the payment form.

<form action="{{ url('/payu/payment-link') }}" method="POST">
    @csrf
    <label for="amount">Amount:</label>
    <input type="text" id="amount" name="amount" required>
    
    <label for="name">Name:</label>
    <input type="text" id="name" name="name" required>
    
    <label for="email">Email:</label>
    <input type="email" id="email" name="email" required>
    
    <label for="phone">Phone:</label>
    <input type="text" id="phone" name="phone" required>

    <label for="description">Description:</label>    
    <input type="text" id="description" name="description" required>
    
    <button type="submit">Generate Payment Link</button>
</form>

Step 4: Testing the Payment Link Generation

To test the payment link generation:

1. Start your Laravel server: php artisan serve
2. Navigate to the form URL.
3. Fill in the details and submit the form.
4. The system should generate a PayU payment link and return it in JSON format.

{
  "status": 0,
  "message": "paymentLink generated",
  "result": {
    "subAmount": 2,
    "tax": 0,
    "shippingCharge": 0,
