Vortex Release Version (April 26, 2026)

• Enhanced Apple Pay error logging to include response codes and messages for all failed requests, ensuring detailed response data is captured in logs and improving visibility for troubleshooting transaction failures.
• Aligned AMEX POS data mapping by ensuring Field 22 authorization values are correctly propagated to settlement records across supported processors, including proper positional mapping for Fiserv Omaha, resolving inconsistencies and ensuring accurate transaction processing.
• Aligned Mastercard ACS service configuration with other card networks to ensure consistent routing to correct aggregator environments across non-production setups, enabling uniform traffic routing to QA and UAT simulators.
• Enhanced Checkout responses for account verification transactions by mapping network-level cardholder name verification results into the Checkout risk object, ensuring fields for account name response and match indicators are accurately populated based on issuer responses.
• Introduced feature flags in ACS Stripe to control L2 and L3 processing, enabling dynamic inclusion of request data and enforcement of arithmetic validation on line items through configuration without requiring deployment.
• Created a design document outlining the implementation of Stripe Vault and Forward API within Vortex, defining integration approach, data flow, and key considerations for securely retrieving and forwarding card data.
• Added support for EMV request data in ACS Stripe behind a feature flag, enabling ingestion and parsing of device, swipe, and EMV payloads into TLV format, with extraction of sensitive and non-sensitive tags and fallback behavior for card-not-present transactions when disabled.

Impact

These updates improve logging visibility for Apple Pay transactions, ensure consistent and compliant data mapping across processors and card networks, and enhance Stripe integration flexibility through configurable feature flags. They also expand support for EMV data handling and provide a clear design foundation for secure card data retrieval and forwarding, strengthening overall transaction processing reliability and observability.
