wheniwork_get_accountread-onlyFetch the When I Work account (workplace) the token acts on — company name, plan and settings; for a parent account also its child accounts. A cheap way to confirm the credentials work. When I Work: GET /2/account.

wheniwork_list_positionsread-onlyList the positions (job roles such as Cashier or Dishwasher) in the account. When I Work: GET /2/positions.
wheniwork_list_shiftsread-onlyList scheduled shifts in a time window — who works when, where and in which position — optionally including open shifts and unpublished drafts. Answers "who is on on Friday?" and "what open shifts are left?". When I Work: GET /2/shifts.
wheniwork_get_shiftread-onlyFetch one shift by id, including its breaks and publish state. When I Work: GET /2/shifts/{id}.
wheniwork_list_eligible_users_for_shiftread-onlyFind who could take an open shift — either an existing shift (shift_id) or a hypothetical one (start, end, position_id and location_id all required). When I Work: GET /2/shifts/eligible.
wheniwork_list_timesread-onlyList clocked time entries — actual hours worked, clock-in/out times, length and approval state. Use only_open to see who is clocked in right now. When I Work: GET /2/times.
wheniwork_list_time_off_requestsread-onlyList time-off requests in a date range, with the requesting users. Status: 0 pending, 1 canceled, 2 accepted, 3 expired, 4 denied. When I Work: GET /2/requests.
wheniwork_get_time_off_requestread-onlyFetch one time-off request by id, with its message thread and users. When I Work: GET /2/requests/{request_id}.
wheniwork_list_time_off_typesread-onlyList the time-off types (e.g. Personal, Sick, Holiday) and whether each allows paid time. Their ids are the type_id for a new request. When I Work: GET /2/requesttypes.
wheniwork_list_shift_swapsread-onlyList shift requests: swaps, drops and alerts, with the shifts and users involved. Status: 0 pending, 1 approved, 2 declined, 3 completed, 4 canceled, 5 expired. Type: 1 swap, 2 drop, 3 alert. start and end must be given together. When I Work: GET /2/swaps.
wheniwork_list_availabilityread-onlyList availability events — when people said they can or cannot work, including recurring patterns that fall in the window. Defaults to the caller, from now to two weeks out. When I Work: GET /2/availabilityevents.
wheniwork_list_annotationsread-onlyList schedule annotations — announcements, business-closed days and blackout dates when time off is not allowed. Defaults to today through one year out. When I Work: GET /2/annotations.
wheniwork_create_shiftcan modifyCreate one shift on a schedule — assigned to a user, or open (user_id 0). Created as a draft unless published is true. Undo by editing it or unpublishing. When I Work: POST /2/shifts.
wheniwork_update_shiftcan modifyChange a shift — reassign it, move it, change position or notes. When I Work requires start_time, end_time and location_id on every update, so fetch the shift first and pass them back. This tool never sends a breaks array; When I Work documents that breaks omitted from an update's breaks list are removed, so re-check the shift's breaks afterwards. When I Work: PUT /2/shifts/{id}.
wheniwork_publish_shiftscan modifyPublish draft shifts so employees can see them. Publishing does not itself send notifications. Undo with wheniwork_unpublish_shifts. When I Work: POST /2/shifts/publish.
wheniwork_unpublish_shiftscan modifyReturn published shifts to draft, hiding them from employees. Undo with wheniwork_publish_shifts. When I Work: POST /2/shifts/unpublish.
wheniwork_create_time_off_requestcan modifyCreate a time-off request for a user (default the calling user). It starts pending; cancel it with wheniwork_update_time_off_request (status 1). Get type ids from wheniwork_list_time_off_types. When I Work: POST /2/requests.
wheniwork_update_time_off_requestcan modifyChange a time-off request: set its status (0 pending, 1 canceled, 2 accepted/approved, 3 expired, 4 denied) and/or its dates or hours.
