    Bearer API key. The account owner generates a private API key from the Public
    API add-on at https://app.lexware.de/addons/public-api (self-serve; requires a
    paid lexoffice / lexware Office plan) and passes it as `Authorization: Bearer
    YOUR_API_KEY` on every request. The key is a long-lived token scoped to the
    connected organization. There is no OAuth client registration or partner
    application for the standard REST API.
