Manage metafield definitions

• Your app can make authenticated requests to the GraphQL Admin API.
• You're using the GraphQL Admin API version 2021-10 or higher.
• Your app has access to the namespace and the owner type that you want to associate with the metafield definition. You can only create metafield definitions for namespaces and owner types that you have access to.

You can create a metafield definition using the metafieldDefinitionCreate mutation. You can create only one metafield definition at a time.

The following example creates a metafield definition called Ingredients for the PRODUCT owner type, which stores multi-line text, such as a list of ingredients used to make the product.

You can use the metafieldDefinition query to retrieve a metafield definition.

The following example retrieves a metafield definition by using its ID:

You can use the metafieldDefinitionUpdate mutation to update a metafield definition. You can update only the name and description of a metafield definition.

The following example changes a metafield definition's name from Pizza size to Pizza size (inches):

To delete a metafield definition, use the metafieldDefinitionDelete mutation. You can also set an option that, when selected, deletes all metafields that use that definition.

The following example deletes the metafield definition for bakery.ingredients, and also deletes all metafields that use the definition.
