CartModules: GoPay Payment Gateway
Accept GoPay Payments in Your CS-Cart Store
Integrate GoPay — one of the most popular payment gateways in the Czech Republic and Slovakia — directly into your CS-Cart or Multi-Vendor store. Customers choose from a wide range of payment methods through GoPay's secure hosted checkout page.
Key Features

- Redirect-Based Flow — No sensitive data touches your server (PCI SAQ A compliant)
- OAuth2 Authentication — Secure API communication using industry-standard OAuth2 client credentials
- Automatic Order Updates — Payment status is verified on customer return and via server-to-server notification
- Sandbox/Production Toggle — Switch between test and live environments from the admin panel
- Configurable Order Statuses — Map GoPay states (PAID, CANCELED, TIMEOUTED, REFUNDED) to any CS-Cart order status
- Dual Currency Support — CZK (Czech Koruna) and EUR (Euro)
- Idempotent Callbacks — Duplicate callbacks are safely ignored
- Order Line Items — Individual products and shipping are passed to GoPay for detailed payment records
