Features

Updated Canadian Onboarding Document Requirements

The Boarding Documents tab for Canadian merchants has been enhanced to include the full set of required documents for Priority International onboarding, covering both Risk and Underwriting needs while leaving the existing automated Stripe flow unaffected.

Transaction Method Column Update

The Entry Mode column in Transaction Activity and Authorization reports has been renamed to Transaction Method, supporting only the valid values CP, CNP, and Interac for improved clarity and consistency.

Canadian Merchant Tax Rate Display

A new read-only Tax Rate field now appears under the Merchant Pricing tab for Canadian merchants, automatically displaying the correct GST, HST, or QST rate based on merchant location.

Enhancements

TSYS Association Code Default Logic Update

Default onboarding logic has been updated so that accounts boarded through MX Connect under specific banks now automatically receive the correct TSYS Association Code, ensuring accurate pricing and reporting for new merchants while existing merchants will be corrected separately.

Copy Client Function Rework

The Copy Client feature has been rebuilt to prevent duplication of sensitive fields and incorrect parent relationships, correctly regenerating ACL and domain values, clearing all identifying information, and ensuring integrations behave as if a completely new client were boarded.

Global ACH Reject Deduplication

Long-term idempotency has been added to the global ACH reject consumer, preventing duplicate case creation and duplicate reject records by checking existing data before inserting new entries and logging detected duplicates.

Priority International Report Improvements

The reporting experience has been refined with clearer labeling, more accurate field handling, and alignment to updated business rules across Priority International transactional reports.

SMS Settled Report Accuracy Update

The SMS Settled Report now returns only successfully processed transactions within batch details, removing declined responses while preserving batch-level totals to improve accuracy and clarity.

Bugs and Fixes

Surcharge Enforcement Correction

A regression affecting surcharge configuration has been resolved, restoring proper enforcement of the 3% maximum limit and ensuring only percentage-based billing options are accepted across Client and Application pages.

MVV 171 File Generation Fix

A correction was made to the stored procedure responsible for generating MVV update files, ensuring the 171 file contains the required billing element data so that updates can be successfully transmitted to the processor.

CEDP Participation Update for Omaha

Updating a Fiserv Omaha merchant’s Credit Risk settings now correctly maps the "Not Participating" value to the appropriate format expected by the processor, ensuring maintain calls reflect accurate participation status.

PII-Safe Logging Improvements

Universal post-serialization redaction has been added across Vortex APIs to protect sensitive identifiers—including TINs, SSNs, and card numbers—ensuring all logs consistently mask critical fields without relying on schema flags.

Email Template Configuration Fix

AWS configuration files for MXC email templates have been corrected to restore proper template loading and ensure expected delivery of system emails.
