Vortex Release Version (December 7, 2025)

New Features and Updates

• Refund validation has been expanded so that all payment types now follow the same over-refund protection rules. Refund attempts can no longer exceed the original or remaining refundable amount for any payment type, and the refunded-amount field is now consistently updated whenever a refund is processed.
• Surcharge logic for mobile wallet payments has been updated so that MX Advantage now evaluates the underlying card type in Apple Pay transactions. Surcharges are applied only when the transaction is classified as credit. Debit, prepaid, and store-value cards are treated as debit and receive the correct compliant surcharge behavior across both enrich and payment routes.

Impact

These updates strengthen the reliability and compliance of the payment ecosystem by ensuring surcharges are applied accurately for Apple Pay transactions and by standardizing refund validation across all payment types. This reduces operational risk, prevents incorrect fees or over-refunds, and provides merchants with more consistent, predictable behavior across mobile-wallet payments and refund workflows.
