Inventory is a representation of a physical good in a warehouse. Each product has one or more inventory items associated with it.

Each inventory_item_id returned from the Product endpoint maps to the id field in the Inventory endpoint.

To most accurately map a sku or Product Name to inventory levels, first call the Product endpoint to get the inventory_item_id list. Then, call the /wms-api/inventory/{inventory_item_id} endpoint to get the inventory levels for each Inventory Item.
