Deletes a category.
When you delete a category, any services linked to it remain associated with the now-deleted category. Wix Bookings still displays these services to business owners in the dashboard, but they aren't visible to customers on the live site.
Attempting to call Update Service (SDK | REST) for a service that's linked to a deleted category fails, unless you specify a different, existing category ID in service.category.id.
You can only call this method when authenticated as a Wix app or Wix user identity.
This method doesn't return any custom errors, but may return standard errors. Learn more about standard Wix errors.
