Production Release 5.29

Section 1: All Customers

This section will provide release notes relevant to All iVeri Customers, categorized into compliance, optimization, and feature enhancements.

Features

Subject: Add merchant webhook notifications for successful Lite transactions

Product/Platform: Gateway – Lite

Release Description:

Added support for posting signed transaction webhook notifications to a configured merchant endpoint after successful Lite transactions. Merchants can configure a webhook endpoint URL, transaction authentication type, and authentication secret; the gateway posts the transaction result payload with a LiteWebhookSignature so the merchant server can verify the notification.

Subject: Add BackOffice configuration for transaction authentication and webhooks.

Product/Platform: Gateway – Lite

Release Description:

Added BackOffice parameter choices and translations for transaction authentication type, authentication secret, and webhook endpoint URL. This introduces configurable Legacy, Merchant, and Application authentication modes for supported transaction integrations.

Subject: Add transaction type filtering to shared transaction views

Product/Platform: Gateway – BackOffice

Release Description:

Added a transaction type filter to shared transaction screens so users can filter batches by All, Authorisation, or Debit. The filter is wired into the shared transaction helper and date-selection UI.

Subject: Allow URL-encoded requests for file downloads

Product/Platform: Gateway – Admin

Release Description:

Updated the Portal Web API file download endpoint to accept both multipart/form-data and application/x-www-form-urlencoded requests. This improves compatibility with clients that post file-download commands as URL-encoded form data.

Compliance

Subject: Extend DCAP customer address data support across 3DS/MPI providers

Product/Platform: Gateway – Core

Release Description:

Extended the DCAP mechanism used for 3DS/MPI risk and authentication data so customer billing and shipping address details can be posted to additional MPI providers. BankServ is the existing implementation reference; Netcetera, CyberSource, and MPGS are the additional 3DS/MPI rollout areas.

Subject: Add card acceptor URL and customer service phone compliance data

Product/Platform:  Gateway – Core

Release Description:

Added support for card acceptor compliance data used by provider transaction processing, including the merchant/acceptor URL and customer service phone number. CSC/FIS and RAPostBridge/RAPostilion provider implementations were updated in this release to populate acceptor website and customer service phone fields into provider-specific message data.

Subject: Fix trading adjustment user details in AcquirerAdmin transaction profiles

Product/Platform: Gateway – BackOffice

Release Description:

Updated AcquirerAdmin transaction profile handling to use nullable database result fields for trading adjustment and user details. This fixes incorrect null handling when displaying iVeri and BackOffice user information for transaction trading adjustments.

Section 2: Client Specific

This section will present client-specific release notes, organized in compliance, optimization, and feature categories, as applicable. Please note that additional information has been included to identify the client.

Features

Client: Stanbic

Subject: Add N-Genius provider and external 3DS support

Product/Platform: Gateway – Core

Release Description:

Added N-Genius provider support, Portal website/service integration, external 3DS flow handling, and supporting database fields. This includes the NGeniusExternal3DSEnabled provider parameter, NGeniusTokenVault persistence in GatewayCentral, additional 3DS-provider table fields, and V_XML flow-control fields such as TransactionReference and PendingAction for multi-step N-Genius transactions.

The integration adds a full N-Genius API consumer in the gateway, NINGenius provider host/router services, Portal Web API and provider support, external 3DS message processing, and supporting database schema and stored procedures.

Client:  CSC

Subject: Add CSCFIS BNMB Sudan provider, router, and settlement support

Product/Platform: Gateway – Core

New provider for Blue Nile Mashreg Bank (Sudan) — live/test provider hosts, router services, settlement upload console, database config, restore scripts, and change-control settings. Cloned from the CSCFIS BOK Sudan baseline, configured for SDG, and scoped to the initial card-not-present requirement.

Client: CBZ

Subject: Add Zimswitch recurring transaction support for CBZ

Product/Platform:  Gateway – Core

Release Description: 

Zimswitch and CBZ Postilion processing now supports recurring transaction flows. CBZ authorisation and debit handling routes to PreAuthorizePayment and DebitPayment when no oppwa_UniqueID is present, and to a payment-status lookup once one exists. Zimswitch now creates a default ShopperResultUrl when one isn't supplied, and Portal has a new Zimswitch controller endpoint for unexpected MIT redirects.

Client: FNB

Subject: Improve PayShap account number and ShapID handling in Lite and DiVert

Product/Platform:  Gateway – Core

Release Description: 

PayShap account-number and ShapID capture improved for Lite and DiVert. The payment model now surfaces guidance that the branch code prefixes the account number, and the flow accepts ShapID, account number, and customer name before processing PayShap transactions.

Client:  FNB

Subject: Add FNB BICISO incremental authorisation support

Product/Platform: Gateway – Core

Release Description: 

Added FNB BICISO handling for incremental authorisation and related reversal data. The implementation includes replacement amount handling through DE95, response acquirer trace support, and lifecycle indicators for pre-authorisation and incremental authorisation flows.

Client:  FNB

Subject: Add MDES support for Mastercard e-commerce and CNP transactions processed to FNB

Product/Platform:  Gateway – Core

Release Description: 

Added MDES tokenisation handling for Mastercard e-commerce and card-not-present transactions processed to FNB. The provider flow can retrieve the MDES payment cryptogram, use the token TAVV in Mastercard authentication data, populate Token CE for Mastercard AAV/token data, and create Token F4 wallet indicators for Mastercard tokenised transactions.

Client:  Standard Bank

Subject: Apply branding to the Standard Bank South Africa BackOffice instance

Product/Platform: Gateway – BackOffice

Release Description:

Added SBSA BackOffice branding, including the SBSA theme assignment, logo, and primary colour styling for the Standard Bank South Africa BackOffice instance.

Compliance

Client: CSC/CBZ

Subject: Mastercard MPGID Support for I&M Bank

Product/Platform: Gateway - Core

Release Description:

This release addresses edge cases affecting online refund processing for card-present transactions.

The following improvements have been implemented:

• Updated DE58 processing to support the corrected online refund flow.
• Modified the BA file to populate the correct CaptureMethod and TerminalCapability values for online refunds of card-present transactions.

These changes improve the reliability and accuracy of online refund and reversal processing, particularly for same-day refund scenarios involving unsettled transactions

Optimisation

Client: Nedbank

Subject: Improve NBPostilion account validation EMV and POS data handling

Product/Platform:  Gateway - Admin

Release Description:

Updated account-validation processing around EMV and POS data so NBPostilion account-validation transactions handle EMV amount, EMV transaction type defaults, zero EMV amount/cash amount cases, and POS data-code combinations more consistently. This reduces issuer/acquirer declines caused by mismatched EMV, swipe, and account-validation data.

Section 3: iVeri Internal

Please note that the release notes below, in addition to Sections 1 & 2, are tailored specifically for iVeri Staff's knowledge and reference.

Compliance

Subject: Track transaction processing excellence compliance scenarios

Supported Product/Platform:Gateway - Core

Release Description:

Continued migrating gateway, portal, provider, reporting, utility, and service projects to the SDK-style project structure used by the .NET 10 codebase. Product projects and build-time tooling stay separated, and legacy build utilities are kept where NAnt and DbFoil generation still need them.

Subject: Continue .NET 10 project and build modernisation

Supported Product/Platform: Gateway - Core

Release Description:

Transaction Processing Excellence tickets covering scheme compliance and operational scenarios: final authorisation timing, nominal amount authorisations, preauthorisation reversal/clearing, message format errors, excessive reattempts, never-approved reattempts, merchant advice code handling, M/Chip deployment performance, undefined authorisations, and 3DS v1 format-error handling.

Optimisation

Subject: Align DbFoilUtil and NAnt build tooling for the modernised build

Product/Platform: Gateway - MerchantAdmin

Release Description:

Custom NAnt tasks and supporting build utilities — DbFoilUtil, iVeriConfig, KeyRingSupplierInterface — moved into source.nant. DbFoilUtil stays available as a build-time dependency for generated database access and projects that still reference the compiled utility, while the source layout is now separate from product runtime projects.

Subject: Improve shared HTTP and certificate utility handling

Product/Platform: Gateway - MerchantAdmin

Release Description:

Updated shared HTTP and certificate utilities used by gateway integrations. The changes support downstream provider integrations and common request handling.

Subject: Improve Partner Gateway forwarding request headers

Product/Platform: Gateway - Core

Release Description:

Updated Partner Gateway forwarding to send the Accept-Charset: utf-8 header through the typed request header collection instead of unvalidated header insertion. This keeps legacy charset compatibility while aligning the forwarding request with standard .NET HTTP header handling.

Subject: Update install manifests and deployment scripts for the release

Product/Platform:  Gateway - Core

Release Description:

Updated install and deployment manifests for the release, including service registration, scheduled tasks, server update build steps, and latest-file inclusion lists. Change-control update manifests were also updated for new provider and release components.
