Get All Metafields

Retrieve all metafields associated with the store or a specific resource. Metafields are custom key-value pairs that extend standard EcartAPI resources with additional data beyond the unified schema. Common use cases include storing third-party integration data, custom product attributes, B2B customer metadata, and platform-specific fields not exposed in the standard schema.

EcartAPI normalizes metafield data to include the namespace, key, value, and value type across platforms that support custom metadata.

Note: Metafields are currently supported on Shopify. Each metafield is scoped to a resource type (store, order, product, product variant). Use the namespace and key parameters to filter by specific metafield groups.
