- You've completed the Getting started with the Storefront API guide.
- You've created resources that support metafields in your store, and you've created metafields for those resources.

Anchor to Step 1: Expose metafieldsStep 1: Expose metafields
To create a MetafieldStorefrontVisibility
record, you can use the metafieldStorefrontVisibilityCreate
mutation in the GraphQL Admin API. The input object for the mutation uses the following fields:
-
namespace
— The namespace of the metafields to be visible to the Storefront API. -
key
— The key of the metafields to be visible to the Storefront API. -
ownerType
— The core resource that owns this metafield. For example,PRODUCT
.
The following example creates a MetafieldStorefrontVisibility
record that exposes all product metafields that have the namespace testapp
and the key pizza-size-inches
:
POST https://{shop}.myshopify.com/api/{api_version}/graphql.json
GraphQL mutation
JSON response

After exposing metafields, you can retrieve them with the Storefront API by using the metafield
field. You can retrieve a single metafield for a product or a product variant. To specify the metafield that you want to retrieve, use the namespace
and key
arguments.
In the following example, you have a product called "Amazing Frozen Pizza" and you've created metafields that store the size of the pizza and the pizza's expiration date. You want to display those values on the storefront according to each metafield's type. The following example shows how to retrieve the value and type for each metafield using the Storefront API.
POST https://{shop}.myshopify.com/api/{api_version}/graphql.json
GraphQL query

If you no longer need to access a metafield with the Storefront API, then you can hide it again by using the GraphQL Admin API to delete the MetafieldStorefrontVisibility
record that you created.
To delete a MetafieldStorefrontVisibility
record, you need to provide its ID to the metafieldStorefrontVisibilityDelete
mutation.
The following example retrieves a list of MetafieldStorefrontVisibility
records. Each result returns the object's id
, namespace
, key
, and ownerType
.
POST https://{shop}.myshopify.com/api/{api_version}/graphql.json
GraphQL query
JSON response
The following example uses one of the returned IDs to delete the MetafieldStorefrontVisibility
that has the namespace testapp
and the key pizza-size-inches
.
POST https://{shop}.myshopify.com/api/{api_version}/graphql.json
GraphQL mutation
JSON response
