# First Horizon — API Banking

> First Horizon Bank operates an API Banking developer portal for Treasury Management clients,
> exposing RESTful products for money movement, ACH origination, real-time account information,
> and routing-number/BIC lookups. APIs are secured with OAuth 2.0 and exercisable in a sandbox
> before promotion to a live customer environment. Onboarding is partner/relationship gated and
> no public OpenAPI/Swagger specification is downloadable; endpoints are documented in HTML on
> the developer portal.
