We are working on implementing GetFulillments API call and in between we found that
the Fulfillments API response is not coming with ShippedItems. We tried to send IncludeShippedItems=true as we do it for the GetShipments API call.But this filter is not available for the Fulfillments API.
Additionally, we conducted some research on this and found that the Fulfillments API does not support including ShippedItems.
So, can you please let us know what the alternative way to obtain these items for fulfillments, i.e., any other API call or filter that we don't know about? For reference attaching images for 
GetShipments(single Order),
GetFulillments(Single Order).
Endpoint Urls used for
1) Shipments API call => https://ssapi.shipstation.com/shipments?includeShipmentItems=true&orderId=36654590
2) Fulfillments API call => https://ssapi.shipstation.com/fulfillments?orderNumber=58V7948727006022V&IncludeShippedItems=True
Please let us know how can we get the required details in fulfillments response.
