Async Account Statement Generation​

Nium has revamped the account statement experience with asynchronous report generation.

Alternatively, statements can be pushed directly to your SFTP server — supporting password-based, SSH key-based, and SSH key + password-based authentication. The new statement APIs are part of the Reports section, a unified API set built to support multiple report types with a single integration.

Core Platform​

Introducing Live-Authorization for EU Applications​

Live-authorization is a digital alternative to paper-based Power of Attorney (POA) verification.

• For EU applications, any applicant who is not a director must provide a POA signed by a director. If the director is based outside the EEA, this POA must be verified by an apostille.
• Live-authorization is completely digital, requires no apostilization, and requires no manual review, accelerating the verification process.

Live-authorization is currently available for EU applications and will be expanded to other regions soon.
For more information, see Letter of Authorization.

Onboarding Guide Changes​

We have upgraded our onboarding guides for the US region to include the following:

• Addition of optional documents such as Proof of Business and Ownership Chart to improve approval TATs. A Template for Ownership Chart has been added.
• Improved guidance on key topics such as:
  • How to add positions
  • Expected documents for Proof of Business / Source of Wealth
  • New optional fields such as expectedAccountUsage and natureOfBusiness to avoid RFIs
