CartModules: Barion Smart Gateway

Integrate Barion Smart Gateway, Hungary's leading online payment solution, 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, Barion Wallet, and other popular Central European payment methods.

Key Features

  • Dual Checkout Modes — Choose between redirect (hosted page) or inline (embedded Smart Gateway) checkout
  • On-Site Payment — Inline mode keeps customers on your store during payment
  • Apple Pay & Google Pay — Accept wallet payments in inline mode on supported devices
  • Hosted Payment Page — Customers are redirected to Barion's secure payment page, keeping your store PCI SAQ A compliant with no direct card handling.
  • Barion Smart Gateway API v2 — Connects to Barion's modern REST API using POSKey authentication for reliable payment processing.
  • Server-to-Server Callbacks — Reliable order status updates via Barion's CallbackUrl system, even if the customer closes their browser.
  • Multi-Currency Support — Accept payments in Hungarian Forint (HUF), Euro (EUR), US Dollar (USD), and Czech Koruna (CZK).
  • Sandbox Mode — Test the full payment flow using Barion's sandbox environment before going live.
  • Line-Item Details — Product names, quantities, and shipping costs are sent to Barion for detailed transaction records.
  • Automatic Locale Detection — The payment page language is set automatically based on the customer's store language.
  • Configurable Status Mapping — Map Barion payment outcomes (Succeeded, Failed, 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 (POSKey) automatically stripped.
  • Clean Uninstall — Removes all database entries on uninstallation with no residual data.

How It Works

  1. Customer selects Barion at checkout and places the order.
  2. The addon creates a payment via the Barion Smart Gateway API.
  3. Customer is redirected to Barion's hosted payment page to complete payment.
  4. Barion sends a server-to-server callback to your store confirming the payment result.
  5. The order status is updated automatically and the customer sees the confirmation page.

Checkout Modes

  • Redirect (Default) — Customer is redirected to Barion's secure hosted payment page
  • Inline (Embedded) — Barion Smart Gateway JS SDK renders an embedded payment form directly on your checkout page, with support for Apple Pay and Google Pay
