Citi Money Movement API
The Citi Money Movement API enables authorized payment initiation from Citi retail accounts, including domestic ACH, wire, and internal book transfers, on behalf of a consenting customer. It is one of the seven core products in the Citi Developer Hub retail catalog. Authentication uses OAuth 2.0 with strong-customer-authentication consent flows, and production access requires partner onboarding. Documentation is HTML-only; no downloadable OpenAPI, SDK, or Postman collection is publicly available.
