Why merchants use it

• Improve conversion — fast, familiar checkout with flexible flows and optional saved cards that reduce friction and cart abandonment.
• Reduce fraud — built-in 3D Secure and risk controls protect transactions without hurting the customer experience.
• Operate efficiently — capture, void, and refund directly from the WooCommerce order screen, with webhooks keeping your store and the gateway in sync.

Flexible checkout options

• Hosted Session — embedded secure payment fields with saved-card support.
• Hosted Checkout – Embedded — Mastercard-hosted form inside an iframe.
• Hosted Checkout – Redirect — standalone Mastercard page for the lowest PCI effort.

External services

This plugin connects to the Mastercard Merchant Cloud payment gateway (Mastercard Gateway API) to process payments. This service is required for the plugin to function. The gateway endpoint is region-specific and selected by the Merchant Region you configure (for example https://<region-gateway-host>/api/rest/...). This service is provided by Mastercard. See Mastercard’s terms of service: https://developer.mastercard.com/terms-of-use and privacy policy: https://www.mastercard.com/us/en/global-privacy-notice.html.
