# Variants

A variant is a Shopify product variant that Auction Plus tracks for a shop. The **externalId** attribute is the Shopify variant ID, and **displayName** combines the product and variant titles for display. The **price** attribute is returned as a price object containing **value** (minor units), **major**, **display**, and **currency** fields.

Variants are looked up by Shopify variant ID through the required `filter[externalId]` parameter.

Include **currentAuctionItem** to return the variant's live auction item alongside it.
