Test Nium with our new Simulation requests

Nium has introduced enhanced Simulation APIs to help developers test various services and refine their integrations confidently. This suite allows you to simulate different scenarios across onboarding, payouts, and compliance transitions. By leveraging these simulations, clients can ensure their implementation meets real-world demands without impacting actual operations. Available tests include:

• Onboarding Simulations: Test the compliance statuses for individual and corporate accounts, ensuring readiness before live operation.
• Payout Simulations: Validate transaction flows, including error handling and response to different compliance requirements.
• Flexible Status Transitions: Move transactions through various lifecycle statuses, such as RFI_REQUESTED, PAID, or ERROR, to verify end-to-end processes.

For step-by-step guides and API details, see Testing Nium.

Nium Verify

Ensure accurate bank details and reduce payment failures with real-time account verification. For more information, see Nium Verify.

Enhancements

Multiple Wallets - Account Statement

Clients can now generate account statements for a specific wallet using the Fetch Wallet Statement request. This change helps you better reconcile and manage the different wallets you create.

For more information, see Customer Account Statement.

API Breaking Changes

Biometric Authentication Requirement

Nium will begin updating authentication requirements for online card transactions in line with the latest requirements from card issuers. These changes aim to enhance transaction security and improve the cardholder’s experience by implementing more robust authentication measures.

By April 1st, 2025, all NIUM clients must enable biometric authentication for online transactions made on devices that support biometric verification (e.g., fingerprint or facial recognition). Clients will need to integrate with Nium’s Out-of-Band (OOB) authentication flow to support this functionality. For more information about implementing, see OOB Authentication Flow.

By integrating biometric authentication for online payments, Nium clients can provide their customers with a more convenient and secure method for verifying transactions. Biometric authentication helps increase the success rate of authentication while reducing fraud in high-risk scenarios.

• Higher authentication success rates
• Increased transaction approval rates
• Reduced fraud on high-risk transactions
• Improved security for step-up authentication when biometrics are used

complianceStatus changes

The complianceStatus returned in the API response will only return RFI_REQUESTED and RFI_RESPONDED beginning January 15th, 2025. For compliance purposes, the remaining values won’t be supported. If you have any questions, please contact your Nium account manager or Nium Support.

Issuance and Cards

There are no updates for this time period.

Payouts and Payins

New Features

New beneficiaryIntermediaryBankCode field

We’ve added a new beneficiaryIntermediaryBankCode to the Transfer Money request to help capture the correspondent’s (also called the intermediary’s) bank code. This new field helps reduce transaction rejections where SWIFT payouts to specific corridors require additional information about the intermediary bank.
