Payment Gateway Integration
Integrate secure payment processing with proper error handling and compliance.
Stripe Integration (Node.js)
const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY);
class PaymentService {
async createPaymentIntent(amount, currency, customerId) {
return stripe.paymentIntents.create({
amount: Math.round(amount * 100), // Convert to cents
currency,
customer: customerId,
automatic_payment_methods: { enabled: true }
});
}
async createSubscription(customerId, priceId) {
return stripe.subscriptions.create({
customer: customerId,
items: [{ price: priceId }],
payment_behavior: 'default_incomplete',
expand: ['latest_invoice.payment_intent']
});
}
async refund(paymentIntentId, amount = null) {
const params = { payment_intent: paymentIntentId };
if (amount) params.amount = Math.round(amount * 100);
return stripe.refunds.create(params);
}
}
Webhook Handling
app.post('/webhooks/stripe', express.raw({ type: 'application/json' }), (req, res) => {
const sig = req.headers['stripe-signature'];
let event;
try {
event = stripe.webhooks.constructEvent(req.body, sig, process.env.STRIPE_WEBHOOK_SECRET);
} catch (err) {
return res.status(400).send(`Webhook Error: ${err.message}`);
}
switch (event.type) {
case 'payment_intent.succeeded':
await handlePaymentSuccess(event.data.object);
break;
case 'invoice.payment_failed':
await handlePaymentFailed(event.data.object);
break;
}
res.json({ received: true });
});
PayPal Integration
See references/paypal-integration.md for complete PayPal implementation with:
- Order creation and capture
- Refund processing
- Webhook handling
- Frontend SDK integration
- Success/cancel callbacks
Security Checklist
- Use official SDK only
- Verify webhook signatures
- Never log full card numbers
- Store minimal payment data
- Test in sandbox first
- HTTPS for all payment routes
- Handle all error cases
- Use idempotency keys
- Implement retry logic
Best Practices
Do:
- Use official SDK libraries
- Verify all webhook signatures
- Log transaction IDs (not card data)
- Test in sandbox environment
- Handle all payment states
- Implement proper error messages
Don't:
- Process raw card data directly
- Store sensitive payment info
- Hardcode API keys
- Skip webhook signature validation
- Ignore failed payment events
- Use test keys in production
