  description: >-
    freee unified OAuth 2.0. Register an application in the freee Developers
    console to obtain a client_id and client_secret, send the user through the
    authorization code grant, then exchange the code for an access token and
    refresh token. The access token is presented on every API request as
    `Authorization: Bearer <access_token>`. A single freee token works across
    products (accounting, HR/payroll, invoicing) subject to the granted scopes.
    Access tokens are short-lived and are renewed with the refresh token.
