Blog Focus: Ensuring that every payment status update received from HesabPay is genuine, authenticated, and tamper-proof.

1. Why Webhook Verification Matters #

Webhooks play a central role in synchronizing payment status between HesabPay and WooCommerce.
Without proper verification, unauthorized systems could send fake success or failure updates — risking financial discrepancies or fraud.

Webhook verification ensures that:

• Only legitimate requests from HesabPay servers update order statuses.

• Data remains encrypted and authenticated through a signature key.

• Merchants maintain integrity in transaction records and customer trust.

Enterprise Insight:
Unauthenticated webhooks are among the top 3 causes of fraudulent order updates in eCommerce. Proper verification eliminates this threat entirely.

2. How HesabPay Webhook Verification Works #

Each webhook sent from HesabPay includes a secure hash signature, generated using your Merchant PIN or API Key.
Upon receipt, the plugin validates this signature by:

1. Re-generating the signature locally using your stored credentials.

2. Comparing it with the signature received in the webhook header.

3. Proceeding only if both signatures match perfectly.

If validation fails, the webhook is discarded, and the event is logged for review.

3. Implementation Steps #

1. Enable “Webhook Verification” in WooCommerce → Settings → Payments → HesabPay.

2. Enter your valid API Key and Merchant PIN.

3. Confirm your callback URL is HTTPS secured.

4. Enable debug logs during testing to confirm webhook authenticity.

5. Test using Sandbox mode before enabling in Live mode.

Enterprise Tip:
Use IP whitelisting to ensure only HesabPay servers can access your webhook endpoint.

4. Testing and Validation #

To verify webhook setup:

• Place a Sandbox test order.

• Confirm WooCommerce automatically updates the order status.

• Check logs for a “Verified Webhook” entry.

• Review response timestamps for consistency.

Enterprise Tip:
Automate webhook validation in staging environments before moving to production.

5. Maintaining Webhook Security #

• Rotate API keys periodically.

• Disable test webhooks after deployment.

• Use a firewall or WAF to block external access attempts.

• Keep all communication strictly over HTTPS.

Conclusion:
Webhook verification transforms your payment processing into a secure, trusted ecosystem — ensuring that every order update is validated, traceable, and secure.
