YS CART – JKoPay
Direct connection to Jiecun Payment, funds are credited only after amount verification via webhook.
JKOPAY is one of the main mobile payment providers in Taiwan. This plugin directly connects YS CART to JKOPAY's payment gateway – without third-party integrators, with a simple fee structure, from checkout to payment confirmation and fund remittance.
Direct connection to Gateway, easy setup
Enter the store code and key provided byJKOPay to enable the feature. A built-in "Test Connection" button allows you to verify the certificate with a single click. The JKOPay payment option will appear on the checkout page, and payment can be completed by scanning a QR code with your mobile phone or by redirecting through the app.
Please verify the amount before crediting.
Webhooks don't just verify signatures; they also check if the actual payment amount reported by the payment gateway matches the total order amount before marking a payment as complete, ensuring reconciliation. Notifications for discrepancies in amounts are blocked and logged, preventing "order amount modification" attacks.

FAQ
What account is needed?
You need to sign a contract with STREET,Pay to obtain a merchant code and API key. After filling them into the settings page, you can verify by using "Test Connection".
Do you offer refunds?
Order refunds follow the Jiekou store backend process; the order status and records on the plugin side remain synchronized.
How is the safety?
In addition to callback verification, forcibly reconcile the actual payment amount from the payment channel with the total order amount before crediting. All discrepancies in amounts are to be rejected and recorded.
