register the Paytm\JsCheckout\PaytmServiceProvider in your config/app.php configuration file.
// Paytm configuration settings... 'Paytm' => [ 'merchantKey' => env('MERCHANT_KEY',''), 'merchantId' => env('MERCHANT_ID',''), 'enviroment' => env('PAYTM_ENVIRONMENT',''), 'callbackUrl' => env('PAYTM_CALLBACK_URL',''), ],
OR
Add the paytm credentials to the .env file
export PAYTM_ENVIRONMENT=staging export PAYTM_MERCHANT_ID=YOUR_MERCHANT_ID_HERE export PAYTM_MERCHANT_KEY =YOUR_SECRET_KEY_HERE export PAYTM_CALLBACK_URL =YOUR_CALLBACK_URL
Note : All the credentials mentioned are provided by Paytm after signing up as merchant.
Usage
Making a transaction

class PaytmController extends Controller

// display a form for payment
public function initiate()
{
$this->render('paytm');
}
/* Make payment */
public function payment(){
if ($this->request->is('post')) {
$postData = $this->request->getData();
$amount = 1; //Amount to be paid
$order_id = time();

// Set the JSON data as the response body
$this->response = $this->response->withStringBody($jsonData);

}
}
/*Paytm Callback */
public function paymentCallback()
{

$post_checksum = $_POST['CHECKSUMHASH'];
}else{
$post_checksum = "";
}

// Access the POST data from the request
$callbackData = $this->request->getData();
$Paytm = new Paytm();
$requestData = $Paytm->verifyPaymentResponse($_POST);

Making a sucess page
<!-- File: templates/Paytm/success.php -->
<!DOCTYPE html>
<html>
<head>
<title>Order Success</title>
<!-- Add any CSS or other head content here -->
</head>
<body>
<h1>Thank You!!!</h1>
<p style="color:green"><?php echo $msg;?></p>
<!-- Add any other content as needed -->
</body>
</html>
Making a error page
<!-- File: templates/Paytm/error.php -->
<!DOCTYPE html>
<html>
<head>
<title>Order Error</title>
<!-- Add any CSS or other head content here -->
</head>
<body>
<h1>Sorry!!!</h1>
<p style="color:red"><?php echo $msg;?></p>
<!-- Add any other content as needed -->
</body>
</html>
Define routes
Router::connect('/paytm/initiate', ['controller' => 'Paytm', 'action' => 'initiate']);
Router::connect('/paytm/payment', ['controller' => 'Paytm', 'action' => 'payment']);
Router::connect('/paytm/paymentCallback', ['controller' => 'Paytm', 'action' => 'paymentCallback'])->setMethods(['POST']);
Important: The callback_url must not be csrf protected Check out here to how to do that
### Write code in src/Application.php
public function middleware(MiddlewareQueue $middlewareQueue): MiddlewareQueue{
$csrf = new CsrfProtectionMiddleware(['httponly'=>true]);
$csrf->skipCheckCallback(function($request){
$path = $request->getUri()->getPath();
if($path == '/paytm/paymentCallback'){
return true;
}
});
$middlewareQueue
// Catch any exceptions in the lower layers,
// and make an error page/response
->add(new ErrorHandlerMiddleware(Configure::read('Error')))
// Handle plugin/theme assets like CakePHP normally does.
->add(new AssetMiddleware([
'cacheTime' => Configure::read('Asset.cacheTime'),
]))
// Add routing middleware.
// If you have a large number of routes connected, turning on routes
// caching in production could improve performance. For that when
// creating the middleware instance specify the cache config name by
// using it's second constructor argument:
// `new RoutingMiddleware($this, '_cake_routes_')`
->add(new RoutingMiddleware($this))
// Parse various types of encoded request bodies so that they are
// available as array through $request->getData()
// https://book.cakephp.org/4/en/controllers/middleware.html#body-parser-middleware
->add(new BodyParserMiddleware())
->add($csrf);
return $middlewareQueue;
