Request body to create item invoices

Hi,

I am trying to create item invoices. The item invoice body from https://developer.myob.com/api/accountright/v2/sale/invoice/invoice_item/ , seems to have different fields from the Postman collection request body. The request body for the Postman collection seems to have fields such as BillQuantity, which is not in the item invoice body stated in the documentation. So the correct request body to follow is the one that is stated on the API documentation?
