# MetafieldInput - admin - INPUT_OBJECT
Version: unstable

## Description
The input fields to use to create or update a metafield through a mutation on the owning resource.
An alternative way to create or update a metafield is by using the
[metafieldsSet](https://shopify.dev/api/admin-graphql/latest/mutations/metafieldsSet) mutation.

### Access Scopes



## Fields
* [description](/docs/api/admin/unstable/scalars/String): String - The description of the metafield.
* [id](/docs/api/admin/unstable/scalars/ID): ID - The unique ID of the metafield. Using `owner_id`, `namespace`, and `key` is preferred for creating and updating.
* [key](/docs/api/admin/unstable/scalars/String): String - The unique identifier for a metafield within its namespace.

Required when creating a metafield, but optional when updating. Used to help identify the metafield when
updating, but can't be updated itself.

Must be 2-64 characters long and can contain alphanumeric, hyphen, and underscore characters.
* [namespace](/docs/api/admin/unstable/scalars/String): String - The container for a group of metafields that the metafield is or will be associated with. Used in tandem with
`key` to lookup a metafield on a resource, preventing conflicts with other metafields with the same `key`.

Required when creating a metafield, but optional when updating. Used to help identify the metafield when
updating, but can't be updated itself.

Must be 3-255 characters long and can contain alphanumeric, hyphen, and underscore characters.
* [type](/docs/api/admin/unstable/scalars/String): String - The type of data that is stored in the metafield.
Refer to the list of [supported types](https://shopify.dev/apps/metafields/types).

Required when creating or updating a metafield without a definition.
* [value](/docs/api/admin/unstable/scalars/String): String - The data stored in the metafield. Always stored as a string, regardless of the metafield's type.
