# syncBusinessHoursSlots

> Replace the workspace's business hours with the provided set of slots. Each slot defines a weekday, a timezone, and open/close times (HH:MM format). Passing an empty array clears all business hours. This mutation is idempotent and completely replaces any existing slots, including any previously set via the deprecated upsertBusinessHours mutation. Requires the `businessHours:edit` permission.
