How to integrate Malaysia Payment Gateway to your website?

# Step-by-step guide to integrating Malaysia Payment Gateway to your website

To integrate Malaysia Payment Gateway into your website, follow the steps below:

1. Selecting the right payment gateway provider in Malaysia
- Mainstream options:
- FPX (Financial Process Exchange) - Direct Bank Transfer
- GrabPay
- Boost
- Touch 'n Go eWallet
- Maybank2u Pay

2. API integration process

A. FPX bank transfer integration
1. Register for a merchant account: apply on the FPX website or through a supported bank
2. Get API credentials: including merchant ID, API key, etc.
3. Back-end development:
"`php
// PHP sample code snippet (conceptual)
$fpx_url = "https://api.fpx.com.my/payment";
$data = [
'merchant_id' => 'YOUR_MERCHANT_ID',
'amount' => $amount.
'customer_email' => $email.
// ...other required parameters
];

// POST request to FPX API...
“`

B. GrabPay/Boost/TNG e-wallet integration (usually through a third party)
"`javascript
// JavaScript SDK loading example (GrabPay)

“`

C++ Backend Processing Callback Example (Conceptual)

"`cpp
#include
#include

using namespace web.
using namespace http.
using namespace http::experimental::listener;

void handle_post(http_request request) {
if (request.method() == methods::POST) {
request.extract_json().then([=](json::value payload) {
// Verify payment status from payload

json::value response;
response["status"] = json::value("success");

request.reply(status_codes::OK, response);
});
}
}
“`

Python Django View Processing Example

"`python
from django.http import JsonResponse

def payment_webhook(request).
if request.method == 'POST':
# Verify signature from header

# Process payment notification

return JsonResponse({'status': 'received'})

return JsonResponse({'error': 'Invalid method'}, status=400)
“`

Java Spring Boot Controller Example

"`java
@RestController @RequestMapping("/payment")
public class PaymentController {

@PostMapping("/callback")
public ResponseEntity handleCallback(@RequestBody PaymentNotification notification,
HttpServletRequest request) {

// Validate the callback is genuine

return ResponseEntity.ok(Map.of("status", "success"));
}
}
“`

💡 *Hint*: Always refer to the latest official documentation of your chosen payment service provider for the actual implementation, as API details change over time. Most major providers have detailed developer portals and SDKs available.# Malaysia Payment Gateway Integration Advanced Guide

3. Security and compliance considerations

A. PCI DSS compliance
- Credit card processing: if credit cards are involved, ensure PCI compliance
- Sensitive data: never store card number/CVV directly, use tokenisation technology
- SSL/TLS: Mandatory HTTPS (TLS 1.2+)

B. Local regulatory requirements
- BNM Requirements: Compliance with Bank Negara Malaysia (BNM) e-Payment Rules
- GDPR/PDPA: Compliance with Malaysia's Personal Data Protection Act (PDPA)

4. Webhook implementation best practices

"`javascript
// Node.js webhook validation example (using Boost as an example)
const crypto = require('crypto');

function verifyBoostWebhook(req, secret) {
const signature = req.headers['x-boost-signature'];
const hmac = crypto.createHmac('sha256', secret);
const digest = hmac.update(JSON.stringify(req.body)).digest('hex');

return crypto.timingSafeEqual(
Buffer.from(signature),
Buffer.from(digest)
);
}

app.post('/webhooks/boost', (req, res) => {
if (!verifyBoostWebhook(req, process.env.BOOST_SECRET)) {
return res.status(403).send('Invalid signature');
}

// Process payment event...
});
“`

5. React/Vue front-end integration examples

"`jsx
// React component example (Touch 'n Go)
import { loadTngSdk } from '@tng-digital/tng-sdk';

function PaymentButton() {
const handlePayment = async () => {
try {
await loadTngSdk({
merchantId: 'YOUR_MID',
env: 'production'
});

window.TNG.pay({
amount: totalAmount,
referenceId: orderId,
onSuccess: (data) => console.log(data),
onError: (err) => alert(err.message)
});
} catch (error) {
console.error(error);
}
};

return Pay with TNG;
}
“`

6. Laravel back-end processing flow

"`php
// Laravel Routing and Controller Examples (Fpx Processing)
Route::post('/fpx/callback', [FpxController::class, 'handleCallback']);

class FpxController extends Controller
{
public function handleCallback(Request $request)
{
$validated = $request->validate([
'fpx_transaction_id' => 'required',
'amount' => 'required|numeric',
// ...other validation rules...
]);

// Verify transaction with FPX API

if ($this->verifyFpxTransaction($validated)) {
Order::markAsPaid($validated).
return response()->json(['status' => true]);
}

abort(400, "Invalid FPX transaction").
}

protected function verifyFpxTransaction(array $data): bool
{ /* … */ }
}
“`

💡 *Professional advice*:
1️⃣ Sandbox test environment - Always test in sandbox first
2️⃣ Multi-currency support - Consider adding MYR/USD/SGD support
3️⃣ Error recovery mechanism - Implement retry logic for failed transactions
4️⃣ Analytics Dashboard - Build reconciliation reports
