Webhook Security
Secure your webhook endpoints

Webhooks are a critical part of your payment flow. Follow these security practices:

Signature Verification

Always verify webhook signatures to ensure they come from PayFlow:

// Verify webhook signature
const signature = req.headers['x-payflow-signature'];
const payload = req.body;
const expectedSignature = crypto
  .createHmac('sha256', webhookSecret)
  .update(JSON.stringify(payload))
  .digest('hex');

if (signature !== expectedSignature) {
  return res.status(400).json({ error: 'Invalid signature' });
}

HTTPS Only

Always use HTTPS for your webhook endpoints to encrypt data in transit.

Idempotency

Implement idempotency to handle duplicate webhook deliveries safely.
