# POS UI Extensions - Cart API: Customer fields removed from `subscribable` hook

The POS UI Extensions Cart API has been updated, removing the `email`, `firstName`, `lastName`, and `note` Customer fields from the [`subscribable hook`](https://shopify.dev/docs/api/pos-ui-extensions/unstable/apis/cart-api#cartapi-propertydetail-subscribable). Any extension used in POS version 10.0.0 or higher, and any extension targeting API version 2025-01 or higher, won't have access to these fields.

To get this data, update your code to use the `customerId` to retrieve the customer record from the GraphQL Admin API. To do this, your extension must have the `read_customers permission` access scope.

To learn more, read the [POS UI Extensions](https://shopify.dev/docs/api/pos-ui-extensions) documentation.
