This endpoint updates inventory by overriding the existing values with all the new inventory properties that are specified in the request body, or creates a new inventory if inventory does not exist. If an existing property is not mentioned in the request body, then the value for the existing property will be displayed as null or zero. Inventory is identified based on the combination of location number, channel ID, and item ID or item SKU.
