Metafield
Read and write custom metadata (metafields) attached to store resources.
Metafields let merchants and apps attach custom, structured data to shop-level records and to resources such as products, orders, customers, collections, and pages, extending the default data model with namespaced key/value pairs.
Provides endpoints to list, get, create, update, delete, and count shop metafields, and to manage metafields attached to other owner resources.
