Implementation Guide

How Webhooks Work

Configure your webhook URL in ZezoPay dashboard
Event occurs (payment, subscription, or product purchase)
ZezoPay sends POST request to your webhook URL
Your server receives and processes the data
Respond with 200 OK status code

Best Practices

Response Requirements

Always respond with 200 OK status code within 10 seconds to mark webhook as successful.

Respond Quickly - Process asynchronously, respond immediately with 200 OK
Retry Handling - ZezoPay automatically retries failed webhooks:
- 1st retry: After 5 minutes
- 2nd retry: After 30 minutes
- 3rd retry: After 2 hours
Signature Verification - Always verify webhook signatures for security
Idempotency - Handle duplicate webhook deliveries gracefully

Signature Verification

Node.js Example

const crypto = require("crypto");
 
function verifyWebhookSignature(requestBody, signature, secret) {
  if (!secret) return true; // Skip if no secret configured
 
  const computedSignature = crypto
    .createHmac("sha256", secret)
    .update(JSON.stringify({ data: requestBody }))
    .digest("hex");
 
  return computedSignature === signature;
}
 
app.post("/api/webhooks/zezopay", express.json(), (req, res) => {
  const signature = req.headers["x-zezopay-webhook-signature"];
  const webhookSecret = process.env.ZEZOPAY_WEBHOOK_SECRET;
 
  // Verify signature
  if (!verifyWebhookSignature(req.body, signature, webhookSecret)) {
    return res.status(401).json({ error: "Invalid signature" });
  }
 
  const event = req.body;
  const eventType = event.data?.event;
 
  // Process webhook based on event type
  switch (eventType) {
    case "payment.paid":
      // Handle payment.paid
      console.log("Payment completed:", event.data.payload.payment);
      break;
    case "payment.failed":
      // Handle payment.failed
      break;
    case "subscription.active":
      // Handle subscription.active
      break;
    case "product.purchase.paid":
      // Handle product.purchase.paid
      break;
    // Handle all other events...
  }
 
  // Always respond with 200 OK
  res.status(200).json({ received: true });
});

Security Notice

Always verify webhook signatures in production to ensure requests are coming from ZezoPay and haven't been tampered with.
