Identity and visibility scope of the token owner (admin | vorgesetzter/supervisor | mitarbeiter/employee). Useful as a first call to know whose data is returned when no user_id is given.

Flextime balance (Gleitzeit/overtime account) of a user as of a given date. Defaults to yesterday – the same figure shown on the fortyTimer dashboard. The response contains the exact balance as a signed hours:minutes string (formatted).

Vacation account of a user for one year: entitlement, carry-over, adjustments, used, remaining and pending (requested but not yet approved) days. Defaults to the current year. Values are day counts; half days (0.5) are valid.

Work time entries of a user within a date range (default: last 30 days, max. 366 days), paginated with 50 entries per page. Durations are provided as exact integer minutes (worked_minutes, total_worked_minutes) together with preformatted hours:minutes strings (*_formatted); these minute-exact fields are the authoritative values, decimal hour sums would introduce rounding errors.

Project time bookings of a user within a date range (default: last 30 days, max. 366 days), optionally filtered by project and billability, paginated with 50 entries per page. Durations are provided as exact integer minutes (minutes, total_minutes) together with preformatted hours:minutes strings (*_formatted); these minute-exact fields are the authoritative values, decimal hour sums would introduce rounding errors.

Leave requests (vacation, flextime, sick leave) within the visibility scope of the token owner, filterable by user, status, type and date range (overlap semantics). Note: free-text fields of sick-leave requests are never returned by the API for data-protection reasons.

Users within the visibility scope of the token owner (source of user_id values for the other tools). Active users by default; include_inactive = true also lists deactivated users.

All projects with ID, name and active status (source of project_id values for project time filters).
