# Metafield Definitions available on Order, Collection, and Customer

As of API version 2022-01, you can query for `metafieldDefinitions` on `Order`, `Collection`, and `Customer`. Previously this was only available on `Product` and `ProductVariant`.

Metafield Definitions are used to define a namespace, key, and type across all instances of a type of resource. These definitions enable Admin UI so that merchants can edit these fields in the context of each resource. You can learn more about [Metafield Definitions](https://shopify.dev/apps/metafields/definitions) in the Developer Docs.
