I’ll give you a full working Paytm Payment Gateway integration example in Laravel — step-by-step, including payment page, initiate payment, callback handling, and success/failure handling.

🚀 Full Working Example — Paytm Integration in Laravel (Latest)

1. Install Laravel Paytm Package

First, install a Paytm SDK/library.
I recommend using "anandsiddharth/laravel-paytm-wallet" (easy and popular):

composer require anandsiddharth/laravel-paytm-wallet
Code language: JavaScript (javascript)

2. Configure Paytm Keys in .env

Add your Paytm credentials in your .env file:

PAYTM_MERCHANT_ID=YourMerchantID
PAYTM_MERCHANT_KEY=YourMerchantKey
PAYTM_ENVIRONMENT=local  # use 'production' for live
PAYTM_MERCHANT_WEBSITE=WEBSTAGING
PAYTM_CHANNEL=WEB
PAYTM_INDUSTRY_TYPE=Retail
Code language: PHP (php)

3. Create Paytm Configuration File

Publish the config if needed:

php artisan vendor:publish --provider="Anand\LaravelPaytmWallet\PaytmWalletServiceProvider"
Code language: JavaScript (javascript)

It will create a config/paytm-wallet.php file.

Check it and ensure environment variables are correctly mapped.

4. Create Paytm Controller

Now, create a controller to handle payment:

php artisan make:controller PaytmPaymentController
Code language: CSS (css)

Now edit app/Http/Controllers/PaytmPaymentController.php:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Anand\LaravelPaytmWallet\Facades\PaytmWallet;

class PaytmPaymentController extends Controller
{
    public function initiatePayment()
    {
        return view('paytm-payment');
    }

    public function pay(Request $request)
    {
        $payment = PaytmWallet::with('receive');

        $payment->prepare([
            'order' => 'ORDER_' . uniqid(),
            'user' => auth()->id() ?? 1, // or your user id
            'mobile_number' => '7777777777', // dummy or real
            'email' => 'test@example.com', // dummy or real
            'amount' => $request->amount, // dynamic
            'callback_url' => route('paytm.callback')
        ]);

        return $payment->receive(); // Redirect to Paytm payment page
    }

    public function callback()
    {
        $transaction = PaytmWallet::with('receive');
        $response = $transaction->response(); // Response from Paytm

        if ($transaction->isSuccessful()) {
            // Payment Successful
            return redirect()->route('payment.success')->with('message', 'Payment Successful');
        } elseif ($transaction->isFailed()) {
            // Payment Failed
            return redirect()->route('payment.failed')->with('message', 'Payment Failed');
        }
    }

    public function success()
    {
        return view('payment-success');
    }

    public function failed()
    {
        return view('payment-failed');
    }
}
Code language: HTML, XML (xml)

5. Create Routes in web.php

Add these routes:

use App\Http\Controllers\PaytmPaymentController;

Route::get('/paytm-payment', [PaytmPaymentController::class, 'initiatePayment'])->name('paytm.initiate');
Route::post('/paytm-payment', [PaytmPaymentController::class, 'pay'])->name('paytm.pay');
Route::post('/paytm-callback', [PaytmPaymentController::class, 'callback'])->name('paytm.callback');

Route::get('/payment-success', [PaytmPaymentController::class, 'success'])->name('payment.success');
Route::get('/payment-failed', [PaytmPaymentController::class, 'failed'])->name('payment.failed');
Code language: PHP (php)

6. Exclude Callback from CSRF (Important!)

In app/Http/Middleware/VerifyCsrfToken.php, add:

protected $except = [
    '/paytm-callback',
];
Code language: PHP (php)

✅ This fixes the 419 error you were facing.

7. Create Blade View for Payment Page

Create a blade file: resources/views/paytm-payment.blade.php

<!DOCTYPE html>
<html>
<head>
    <title>Paytm Payment Gateway</title>
</head>
<body>

<h2>Paytm Payment</h2>

<form method="POST" action="{{ route('paytm.pay') }}">
    @csrf
    <label>Amount:</label>
    <input type="text" name="amount" value="100" required>
    <br><br>
    <button type="submit">Pay Now</button>
</form>

</body>
</html>
Code language: HTML, XML (xml)

8. Create Success and Failure Pages

resources/views/payment-success.blade.php

<h1>Payment Successful!</h1>
<p>{{ session('message') }}</p>
Code language: HTML, XML (xml)

resources/views/payment-failed.blade.php

<h1>Payment Failed!</h1>
<p>{{ session('message') }}</p>
Code language: HTML, XML (xml)

📋 Full Flow

🎯 Summary

📌 Bonus Tips

• Always log the Paytm callback response for debugging.
• Validate Paytm signature (CHECKSUMHASH) if needed (package does internally).
• Use unique order IDs every time.
• Move Paytm keys into a secure vault if in production.

🎯 Quick Commands for Copying

composer require anandsiddharth/laravel-paytm-wallet
