  description: >-
    HTTP Basic authentication. The access token is the Base64 encoding of the
    string "API Key:API Secret" (the API Key, a colon character, then the API
    Secret, with no spaces). It is sent as the header
    "Authorization: Basic {token}", alongside a Content-Type header such as
    application/json. Credentials are issued per API Device registered under
    Web Integrations in the Epos Now Back Office; each device has its own
    key/secret pair and can be regenerated, and the token differs for every
    registered device.
