Which field in hardware related apis can be map as product

I am creating freshservice custom app. In that mapping all asset from desktopcentral to freshservice.
There is one mandatory field product while creating asset type hardware. but there no any field available
in desktop central api (api/1.0/inventory/hardware) that can map as product.
Can you please suggest wich field in harware apis can be mapped as product.
