How to Setup Secure Double-Confirm Webhooks for WooCommerce

Webhooks are essential for instant product delivery. When a transaction completes on Whop, a webhook updates your WooCommerce store to mark the order complete and trigger product delivery. A premium whop woocommerce gateway secures this pipeline with double-confirm webhooks to prevent transaction spoofing.

The Risk of Unsecured Webhooks

If your webhook receiver URL is public, an attacker could send spoofed payloads to trigger product delivery without paying. To prevent this, our plugin validates webhook signatures using your Whop client secret.

How Double-Confirmation Works

The verification process consists of two steps:

1. Signature Verification: Checks the incoming payload signature against your Whop credentials.
2. API Double-Confirm: Connects to Whop's backend to verify the transaction status before updating the WooCommerce order.
