  description: >-
    REST API for the CharlieHR small-business HR platform. Exposes a company's
    team members, leave requests, leave allowances, and company structure
    (offices and teams). Authentication uses OAuth 2.0: a Client ID and Client
    Secret are exchanged for an access token that is sent in the Authorization
    header. Endpoints and fields documented here reflect CharlieHR's public API
    documentation; some response field details are not fully published and are
    represented as free-form objects.
