Standard metafield definitions
The following table describes the standard metafield definitions. Standard definitions have specific namespaces and keys that we've reserved to have specific meanings for common use cases. If you need to store data for one of these use cases, then we recommend using the standard metafield, as standard metafields are interoperable across the entire Shopify platform and connect more seamlessly to themes.
