BankUnited

BankUnited, N.A. is a national bank (OCC-chartered National Association) and the principal subsidiary of BankUnited, Inc. (NYSE: BKU), a bank holding company headquartered in Miami Lakes, Florida. With roughly $35 billion in total assets and banking centers across Florida, the New York metro area, Dallas, Atlanta, New Jersey and North Carolina, it is a mid-size regional commercial and consumer bank focused on business banking, commercial lending and treasury/depository services. On the open-finance front, BankUnited runs a first-party developer portal branded the "API Experience Hub" (developer.bankunited.com), a Salesforce Experience Cloud site fronting a MuleSoft Anypoint Exchange catalog with self-service registration, OAuth application provisioning and API contracts; the specific API products and any OpenAPI specifications sit behind portal registration/login rather than being openly downloadable. No FDX-conformant public data-access API or published CFPB Section 1033 posture is documented; consumer-permissioned account data is reached primarily through third-party aggregators (e.g. Plaid) rather than a public first-party consumer data API.

BankUnited publishes 1 API on the APIs.io network. Tagged areas include Financial Services, Banking, United States, Regional Bank, and Commercial Banking.

BankUnited’s developer surface includes authentication, signup flow, developer portal, engineering blog, and 13 more developer resources.
