Overview

Metafields are custom data fields that let you store extra information on products, collections, customers, and other Shopify objects — beyond what Shopify tracks by default. They're the extension layer that lets you add specs, materials, care instructions, or any custom data your store needs.

On Shopify, metafields turn a standard product into a rich data object. A furniture store adds 'dimensions' and 'materials' metafields; a skincare store adds 'active ingredients' and 'skin type.' Metafields can be displayed on storefront pages, used in collections, or sent to apps via the API.

Metafields pair with custom fields (the merchant-facing version), JSON (the format metafields use), and custom development for implementation. They're how Shopify scales to any product type.
