Filters the returned orders by order status (Active or Completed). To retrieve orders with a status of Inactive or Cancelled, you must specify the order IDs (OrderIDArray.OrderID). When you specify OrderIDArray.OrderID, no other filters are used.
For Half.com, you can get some, but not all orders. Orders on Half.com have different order status values from eBay orders. When you set ListingType to Half, set OrderStatus to Shipped. Otherwise, GetOrders may return incomplete information or have indeterminate results.
See the
Field Index to learn which calls use OrderStatus.
