## Description
The input fields for a metafield value to set.

### Access Scopes



## Fields
* [compareDigest](/docs/api/admin-graphql/2025-01/scalars/String): String - The `compareDigest` value obtained from a previous query. Provide this with updates to ensure the metafield is modified safely.
* [key](/docs/api/admin-graphql/2025-01/scalars/String): String! - The unique identifier for a metafield within its namespace.

Must be 2-64 characters long and can contain alphanumeric, hyphen, and underscore characters.
* [namespace](/docs/api/admin-graphql/2025-01/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`. If omitted the app-reserved namespace will be used.

Must be 3-255 characters long and can contain alphanumeric, hyphen, and underscore characters.
* [ownerId](/docs/api/admin-graphql/2025-01/scalars/ID): ID! - The unique ID of the resource that the metafield is attached to.
* [type](/docs/api/admin-graphql/2025-01/scalars/String): String - The type of data that is stored in the metafield.
The type must be one of the [supported types](https://shopify.dev/apps/metafields/types).

Required when there is no corresponding definition for the given `namespace`, `key`, and
owner resource type (derived from `ownerId`).
* [value](/docs/api/admin-graphql/2025-01/scalars/String): String! - The data stored in the metafield. Always stored as a string, regardless of the metafield's type.
