I am working on Data Integration APIs using OData.

Using the help of the community I successfully able to query Sales Order.

Now I want to fetch Inventory details, Invoice details and Ship Notes from Dynamics 365 FO.

I don't know which entity I need to lookup. For example, For Sales Order I used SalesOrderHeaders. Code is given below.

var salesOrders = d365Client.SalesOrderHeaders.Where(x => x.SalesOrderNumber.Equals(sonumber));

Like this which entity I need to refer for Fetching Inventory, Invoice and Ship Notes.
