Description

CartModules: Tpay Payment Gateway

Integrate Tpay, Poland's leading online 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 popular Polish payment methods including bank transfers, BLIK, credit cards, and digital wallets.

Key Features

Hosted Payment Page — Customers are redirected to Tpay's secure payment page, keeping your store PCI SAQ A compliant with no direct card handling.
OAuth2 Authentication — Connects to Tpay's modern Open API using industry-standard OAuth2 Bearer token authentication.
Server-to-Server Notifications — Reliable order status updates via Tpay's callback system, even if the customer closes their browser.
MD5 Checksum Verification — Every notification is cryptographically verified to prevent tampering and ensure data integrity.
Sandbox Mode — Test the full payment flow using Tpay's sandbox environment before going live.
PLN and EUR Support — Accept payments in Polish Zloty and Euro.
Configurable Status Mapping — Map Tpay payment outcomes to your preferred CS-Cart order statuses.
Idempotent Processing — Duplicate notifications are handled safely without re-processing orders.
Secure Logging — All API interactions are logged with sensitive credentials automatically stripped.
Clean Uninstall — Removes all database entries on uninstallation with no residual data.

How It Works

Customer selects Tpay at checkout and places the order.
The addon authenticates with Tpay and creates a transaction via the API.
Customer is redirected to Tpay's hosted payment page to complete payment.
Tpay sends a server-to-server notification to your store confirming the payment result.
The order status is updated automatically and the customer sees the confirmation page.
