  title: Okra API (Historical) Accounts Customers API
  description: RETIRED. Okra was an open finance / open banking infrastructure API for Africa (Nigeria). This OpenAPI documents the historical, now-discontinued REST surface. Okra ceased operations in May 2025 and the host api.okra.ng no longer resolves; the paths and Bearer-secret auth below are CONFIRMED from Okra's official okraHQ/okra-node SDK, but request/response body schemas are MODELED (reconstructed from SDK parameter models and archived documentation) and are illustrative rather than authoritative. Reads and writes alike used POST with a JSON filter body. Account linking happened client-side through the Okra Widget, producing the `record`/`customer` identifiers that data endpoints operate against.
