First Hawaiian Bank

First Hawaiian Bank is Hawaii's oldest and largest financial institution, founded in 1858 and headquartered at First Hawaiian Center in Honolulu. It is a Hawaii state-chartered commercial bank and member FDIC, operating as the principal subsidiary of First Hawaiian, Inc. (NASDAQ ticker FHB), a publicly traded bank holding company. The bank serves consumer and commercial customers through roughly 57 branches in Hawaii plus locations in Guam and Saipan, offering deposit accounts, lending, wealth management, treasury/cash management, and merchant services. On the open-finance front, First Hawaiian operates no public first-party developer portal and publishes no downloadable OpenAPI/Swagger specifications; probes of developer.fhb.com, api.fhb.com, and fhb.com/en/developers returned no host or HTTP 404. Consumer-permissioned account data is reachable only through third-party aggregators (notably Plaid), not a direct bank API. No documented Financial Data Exchange (FDX) participation or published CFPB Section 1033 data-access posture was found as of this record. Its commercial online banking product (FHB Commercial Online, formerly OBC) is a traditional web application rather than a developer-facing API surface.

  name: First Hawaiian Bank Consumer Data Access (Aggregator-Only)
  description: First Hawaiian Bank exposes no public first-party API. Consumer-permissioned account and transaction data is
    available only through third-party financial data aggregators such as Plaid, which handle authentication and connectivity
    on the consumer's behalf. This entry documents that aggregator-only posture; it is not a first-party bank API.
