CartModules: Atmos Payment Gateway
Accept payments from Uzbekistan's most popular card networks. Integrate Atmos into your CS-Cart store to accept UZCARD and HUMO card payments in Uzbekistani Som (UZS). Secure redirect-based flow ensures your store never handles card data directly.Overview
The Atmos Payment Gateway addon connects your CS-Cart or Multi-Vendor store to the Atmos payment system in Uzbekistan. Atmos provides access to the two major domestic card networks — UZCARD and HUMO — enabling you to accept payments from millions of cardholders across Uzbekistan.
The addon uses the modern Atmos REST API with OAuth2 authentication, providing a secure and reliable payment experience for both merchants and customers.
Key Features
- UZCARD & HUMO Support — Accept payments from both major Uzbek card networks
- Secure Redirect Flow — Customers enter card details on Atmos-hosted page (PCI SAQ A compliant)
- OAuth2 Authentication — Modern token-based API security with automatic refresh
- Server-to-Server Callbacks — Reliable order status updates even if the customer closes their browser
- Idempotent Processing — Prevents duplicate order updates from multiple callbacks
- Sandbox Environment — Test your integration before going live
- Configurable Status Mapping — Map Atmos payment results to your preferred CS-Cart order statuses
- Comprehensive Logging — Full audit trail with sensitive data automatically redacted
- Multi-Vendor Compatible — Works with both CS-Cart and Multi-Vendor editions
How It Works
[Payment Flow Diagram]Checkout → Atmos Authentication → Transaction Created → Redirect to Atmos → Customer Pays → Callback → Order Updated
| Step | Description |
|---|---|
| 1 | Customer selects Atmos at checkout and clicks "Place Order" |
| 2 | The addon authenticates with Atmos API and creates a payment transaction |
| 3 | Customer is redirected to the secure Atmos payment page |
| 4 | Customer enters their UZCARD or HUMO card details and confirms payment |
| 5 | Customer is redirected back to your store's order confirmation page |
| 6 | Atmos sends a server-to-server callback to confirm the payment status |
| 7 | Order status is updated automatically based on the payment result |
