Prestashop module for Mastercard Payment Gateway Services

This module integrates Mastercard Payment Gateway Services into your PrestaShop store, enabling you to accept card payments and alternative payment methods through a secure, gateway-hosted interface. It eliminates the need to handle raw payment details directly by offering two distinct integration models — Hosted Checkout and Hosted Session — so merchants can choose the approach that best suits their checkout experience and compliance requirements.

• Hosted Checkout & Hosted Session: Hosted Checkout displays a payment lightbox served by the gateway, keeping sensitive data entirely off your server. Hosted Session gives you control over page layout while still sourcing payment fields from the gateway's JavaScript library.
• Full and partial refunds: Process complete or partial refunds directly from the admin panel without leaving PrestaShop.
• 3DS authentication: Supports both 3DSv1 and 3DSv2 for strong customer authentication, as well as AVS (Address Verification Service).
• Test and Live mode switching: Configure separate credentials for test and live environments and toggle between them without re-entering credentials each time.
• Shopping cart data transmission: Optionally send line-item product details and order totals to the gateway alongside the payment request.

This module is suited for merchants who have an existing account with Mastercard Payment Gateway Services and need a reliable PrestaShop integration. It is particularly relevant for stores requiring 3DS2 compliance, granular refund control, and a flexible choice between a fully hosted payment page or a customisable embedded form.
