Sandbox Mode – How to test your plugin safely ​

This page explains how to use the HUCH WordPress plugin in Sandbox Mode, allowing you to simulate payment flows without moving real money.

Why use sandbox mode? ​

Sandbox mode is useful for:

  • Testing the plugin integration with WooCommerce
  • Checking the order status updates automatically
  • Verifying that the webhook is properly set up
  • Training your team on how the flow works

No real funds are moved in sandbox mode. It is a safe testing environment.

How to enable sandbox mode ​

  1. Go to WooCommerce > Settings > Payments > HUCH
  2. Check the box “Enable plugin”
  3. Use your Sandbox Client ID and Sandbox Secret Key
  4. Ensure the option “Sandbox Mode” is checked
  5. Save changes

Webhook configuration (Test Environment) ​

In your Sandbox HUCH dashboard, set the webhook URL to:

https://yourwebsite.com/wc-api/huch_redirect

Once saved:

  • The Webhook subscription status in your plugin settings should turn green
  • You should receive automatic order updates

How to test a payment ​

  1. Add a product to your cart and go to checkout
  2. Choose HUCH Open Banking as your payment method
  3. Select a test bank or enter a dummy IBAN provided by HUCH
  4. Complete the mock payment flow
  5. Return to your WooCommerce dashboard and verify:
    • Order status changes from "Pending" to "Processing" or "Completed"
    • Confirmation emails are triggered (if configured)

Checklist before going live ​

  • [x] Plugin installed and enabled
  • [x] Sandbox credentials are in place
  • [x] Webhook subscription shows as active
  • [x] Test payments flow correctly
  • [x] Order status is updating in WooCommerce

Notes & Tips ​
