CartModules: Paybox Payment Gateway

Accept Card Payments via Paybox (Verifone) in Your CS-Cart Store

Integrate Paybox (by Verifone) -- one of Europe's leading payment gateways, widely used in France and across Europe -- directly into your CS-Cart or Multi-Vendor store. Customers complete payment on the Paybox hosted payment page using their credit or debit card through a secure HMAC-signed redirect flow.

Key Features

• Hosted Payment Page -- Customers pay on the Paybox-hosted page; no card data touches your server (PCI SAQ A compliant)
• HMAC-SHA512 Security -- All requests and callbacks are signed with HMAC-SHA512 to prevent tampering
• Multi-Currency Support -- EUR, GBP, USD, and CHF
• Sandbox/Production Toggle -- Switch between test and live environments from the admin panel
• Configurable Order Statuses -- Map Paybox response codes to any CS-Cart order status
• Server-to-Server Notification -- PBX_REPONDRE_A ensures order updates even if the customer closes their browser
• Idempotent Callbacks -- Duplicate callbacks are safely ignored
• Auto-Submit Form -- Seamless redirect to Paybox with no manual click required

Requirements

• CS-Cart or Multi-Vendor 4.x
• PHP 7.1 or higher
• Paybox merchant account with HMAC credentials
• Store currency set to EUR, GBP, USD, or CHF
