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.
