# Metafield​Parent​Resource

union

The Shopify resource that owns a metafield. Returned by the `Metafield` object's [`parentResource`](https://shopify.dev/docs/api/storefront/2026-01/objects/Metafield#field-Metafield.fields.parentResource) field, enabling traversal from a metafield back to the resource it's attached to.

## Fields with this union

* [Metafield.parentResource](https://shopify.dev/docs/api/storefront/2026-01/objects/Metafield#field-Metafield.fields.parentResource)

  OBJECT

  [Custom metadata](https://shopify.dev/docs/apps/build/metafields) attached to a Shopify resource such as a [`Product`](https://shopify.dev/docs/api/storefront/current/objects/Product), [`Collection`](https://shopify.dev/docs/api/storefront/current/objects/Collection), or [`Customer`](https://shopify.dev/docs/api/storefront/current/objects/Customer). Each metafield is identified by a namespace and key, and stores a value with an associated type.

  Values are always stored as strings, but the [`type`](https://shopify.dev/docs/api/storefront/current/objects/Metafield#field-Metafield.fields.type) field indicates how to interpret the data. When a metafield's type is a resource reference, use the [`reference`](https://shopify.dev/docs/api/storefront/current/objects/Metafield#field-Metafield.fields.reference) or [`references`](https://shopify.dev/docs/api/storefront/current/objects/Metafield#field-Metafield.fields.references) fields to retrieve the linked objects. Access metafields on any resource that implements the [`HasMetafields`](https://shopify.dev/docs/api/storefront/current/interfaces/HasMetafields) interface.
