Update time off request

Updates a time off request's details (dates, message, days, policy).

This is a full replacement — all fields must be provided, including time_off_request_days with one entry per date (amount_used in seconds, typically 28800 for an 8-hour day).

Approved, paid, or partially paid requests cannot be edited.

If the request was denied, updating it automatically resubmits it (status → submitted).

If the policy does not require approval, the request is auto-approved on update.

Set require_no_shift_overlap to true to reject the update if it overlaps with scheduled attendance shifts.

remove_shifts deletes overlapping attendance shifts only when the policy does not require approval (the request is auto-approved on update). When the policy requires approval, this field is ignored — use the status endpoint to remove shifts at approval time instead.

Note: starts_at and stops_at are interpreted as wall-clock times in the user's configured timezone (any timezone offset in the value is ignored). When all_day is true, the response covers the whole local day, 00:00:00.000–23:59:59.999 in the timezone saved with the request when it was created.
