  mutation

  Creates a metaobject definition that establishes the structure for custom data objects in your store. The definition specifies the fields, data types, and access permissions that all [`Metaobject`](https://shopify.dev/docs/api/admin-graphql/latest/objects/Metaobject) entries of this type share.

  Use the `type` field to create a unique namespace for your metaobjects. Prefix the type with `$app:` to reserve the definition for your app's exclusive use. The definition can include capabilities like publishable status or translation eligibility, to extend how metaobjects integrate with Shopify's features.
