I am testing the API in the sandbox and trying to create an invoice for a specific item which is in the sales inventory. However, the API requires the itemID and this is not stated in the sales inventory page. I tried using the item name but his does not work.
Is there a way to export the inventory including the “item ID” for each item, I need the item ID for the Invoice create api, I can run the invoice Get for individual invoices which will give me the item id for items in a single invoice, however this would take me forever to get all the item Id’s I need.
