Extending

The SfOrder is returned from the GetOrders Method. If the SfOrder structure doesn't contain the information you need for your Storefront, you can extend its logic using the addCustomFields API. The following example demonstrates how to extend SfOrder with a shipments field.

export const unifiedApiExtension = createUnifiedExtension({
  normalizers: {
    addCustomFields: [
      {
        normalizeOrder: (context, order) => ({
          shipments: order.shipments,
        }),
      },
    ],
  },
  config: {
    ...
  },
});

You can override the normalizeOrder, but it's also available to override the smaller normalizers such as normalizeAddress, normalizeShippingMethod.
