UMB Bank

UMB Bank, National Association is the primary banking subsidiary of UMB Financial Corporation (Nasdaq ticker UMBF), a Kansas City, Missouri financial services holding company. UMB is a commercial bank operating under a national (federal) bank charter supervised by the Office of the Comptroller of the Currency (OCC), with roughly $70 billion in assets following its 2025 acquisition of Heartland Financial and branches across the central United States. It offers personal, commercial, and institutional banking, including asset servicing, corporate trust, and healthcare (HSA) services. UMB runs a partner-facing open-banking and Banking-as-a-Service (BaaS) program through its Institutional & Fintech Banking group, exposing REST APIs across risk & compliance, customer onboarding, accounts, information (statements/check images), and cash management. Access is partner-gated through a consultation and contracting process — there is no public self-serve developer portal, no publicly downloadable OpenAPI/Swagger specification, and no published FDX or CFPB 1033 posture. Consumer-permissioned account data is reached primarily through the Plaid aggregator rather than a first-party public API.

UMB Bank publishes 1 API on the APIs.io network. Tagged areas include Financial Services, Banking, United States, Open Finance, and Banking-as-a-Service.

UMB Bank’s developer surface includes documentation, engineering blog, support, getting-started guide, and 7 more developer resources.
