## Mutations

* [metafield​Definition​Delete](https://shopify.dev/docs/api/admin-graphql/latest/mutations/metafieldDefinitionDelete)

  mutation

  Deletes a [`MetafieldDefinition`](https://shopify.dev/docs/api/admin-graphql/2026-10/objects/MetafieldDefinition). You can identify the definition by providing either its owner type, namespace, and key, or its global ID.

  When you set [`deleteAllAssociatedMetafields`](https://shopify.dev/docs/api/admin-graphql/2026-10/mutations/metafieldDefinitionDelete#arguments-deleteAllAssociatedMetafields) to `true`, the mutation asynchronously deletes all [`Metafield`](https://shopify.dev/docs/api/admin-graphql/2026-10/objects/Metafield) objects that use this definition. This option must be `true` when deleting definitions under the `$app` namespace.
