Specification

name

This is the name of product variation aspect. Typically, for clothing, typical aspect names are "Size" and "Color". Product variation aspects are not required immediately upon creating an inventory item group, but these aspects will be required before a multiple-variation listing containing this inventory item group is published. For each product variation aspect that is specified through the specifications container, one name value is required and two or more variations of this aspect are required through the values array.

Note: Each member of the inventory item group should have these same aspect names specified through the product.aspects container when the inventory item is created with the createOrReplaceInventoryItem or bulkCreateOrReplaceInventoryItem call.
