fullfillment details in the developer section

[SOCCERWORLD]

Can someone tell me if fulfillment pulls all the items just like the shipments?  Or is this just another lack of updating the developer documentation?   If this part of the system can't pull items.. WOW, how bad is that!  Please help with this detail!!!!!!  do i use IncludeFullfillmentItems = true..  really bad. 

CURLOPT_URL => 'https://ssapi.shipstation.com/fullfillment?OrderNumber'.$_REQUEST['order_number'].'&IncludeShipmentI...'],

update:   CURLOPT_URL => 'https://ssapi.shipstation.com/fullfillments?OrderNumber'.$_REQUEST['order_number'].'&IncludeFullfill...',

I have this where it should be: 

CURLOPT_URL => 'https://ssapi.shipstation.com/fulfillments?orderNumber'.$_REQUEST['order_number'],
CURLOPT_RETURNTRANSFER => true,

I am syncing fulfillment to the database on our system .. but I need the items that were part of this package that was put together.
