Features

Support for Interac Card Payments Across MXM

MX Merchant now fully supports Interac as a recognized card type. This enhancement includes updates to the MXG.Transaction_Lookup_CardType table, the CardType enum in the Checkout API, and visible support in the MX Merchant user interface with the Interac logo. These platform-wide changes enable merchants to process Interac payments with consistent recognition, improving compatibility for Canadian debit card users and expanding acceptance options within MXM.

Enhancements

Terminal API — Interac Card Support in Stripe Payment Flow

The Terminal API now includes interac_present in the payment_method_types list when initiating Interac card transactions through Stripe. This update ensures that Interac card payments are accurately identified and processed within the terminal Stripe flow. By explicitly supporting Interac at the API level, terminal transactions benefit from improved reliability and compliance when interacting with Interac-enabled cards.

Terminal Refunds — Interac Card Support in UI and API

Refunds for Interac card transactions are now supported directly through MX Merchant terminals. A new Terminal API endpoint has been introduced to manage Interac refund routing, and the UI has been enhanced to prompt users to select a terminal when initiating these refunds. The refund process requires the original card and terminal to be present and is finalized only after terminal confirmation. Additionally, the ReferenceNumber field has been extended to handle complete Stripe IDs, ensuring precise tracking and successful refund processing.
