  description: >-
    Per-administrator sevdesk API token - a 32-character hexadecimal string
    found in the sevdesk web application under the user's settings. Passed as
    the raw value of the `Authorization` header (no `Bearer` prefix), for
    example `Authorization: b7794de0085f5cd00560f160f290af38`. Tokens have an
    infinite lifetime and can be regenerated (confirmed with the account
    password) to revoke a previous token. Self-serve: any paying account
    administrator can obtain a token with no separate application or approval.
