Extending

The SfCustomer model is returned from Unified Methods such as RegisterCustomer, LoginCustomer and GetCustomer. If the SfCustomer 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 SfCustomer with a country field.

export const unifiedApiExtension = createUnifiedExtension({
  normalizers: {
    addCustomFields: [
      {
        normalizeCustomer: (context, user) => ({
          country: user.defaultAddress?.country,
        }),
      },
    ],
  },
  config: {
    ...
  },
});

Source

SAP User have some fields optional on the interface, but in the reality a valid User should contain a customerId, uid, firstName, and lastName, so if any of these information is missing, normalizer returns an error.

customer.ts
import { defineNormalizer } from "../defineNormalizer";

export const normalizeCustomer = defineNormalizer.normalizeCustomer((context, user) => {
  if (!user.customerId || !user.uid || !user.firstName || user.lastName === undefined) {
    throw new Error("Missing required fields for customer");
  }

  return {
    id: user.customerId,
    firstName: user.firstName,
    lastName: user.lastName,
    email: user.uid,
  };
});
