CartModules: Comgate Payments

Integrate Comgate Payments, Czech Republic's versatile payment gateway, directly into your CS-Cart or Multi-Vendor store. This addon provides a secure hosted payment page flow so your customers can pay using bank cards, Czech bank transfers, and mobile payments.

Key Features

• Hosted Payment Page — Customers are redirected to Comgate's secure payment page, keeping your store PCI SAQ A compliant with no direct card handling.
• Comgate REST API — Connects to Comgate's payment API using Merchant ID and Secret authentication for reliable payment processing.
• Server-to-Server Callbacks — Reliable order status updates via Comgate's callback system, even if the customer closes their browser.
• Multiple Payment Methods — Accept cards, Czech bank transfers, and mobile payments through a single integration.
• Multi-Currency Support — Accept payments in Czech Koruna (CZK) and Euro (EUR).
• Sandbox Mode — Test the full payment flow using Comgate's test mode before going live.
• Automatic Language Detection — The payment page language is set automatically based on the customer's store language.
• Configurable Status Mapping — Map Comgate payment outcomes (Paid, Cancelled, Pending) to your preferred CS-Cart order statuses.
• Idempotent Processing — Duplicate callbacks are handled safely without re-processing orders.
• Secure Logging — All API interactions are logged with sensitive credentials (Secret) automatically stripped.
• Clean Uninstall — Removes all database entries on uninstallation with no residual data.
