Custom fields that store additional information about a Shopify resource, such as products, orders, and many more. Using metafields with Shopify Functions enables you to customize the checkout experience.

Fields

• key (String!) Required

  The unique identifier for the metafield within its namespace. A metafield is composed of a namespace and a key, in the format namespace.key.

• namespace (String)

  A category that organizes a group of metafields. Namespaces are used to prevent naming conflicts between different apps or different parts of the same app. If omitted, then the app-reserved namespace is used.

• type (String!) Required

  The type of data that's stored in the metafield.

• value (String!) Required

  The data to store in the metafield.
