RFI Flow v5
Introduced RFI Flow v5 — a unified integration for handling all requests for information across onboarding, transactions, and refunds. This replaces the need to maintain separate RFI flows per entity type. A single set of webhooks and APIs now covers every situation in which Nium needs additional information from the client, with self-describing payloads that support text, choice, address, file attachment, identity document, date, confirmation, and URL question types.
Requires enablement by your Nium account manager. For more information, see RFI Flow v5 Integration Guide.
There are no changes at this time.
