# 2026-02-11: Cart Service - restriction property for carts

## Overview

The `Cart` object was extended with a new `restriction` property. This property is an access control identifier that determines who can view or manage the cart.

The `restriction` field:

* Restricts cart visibility based on scope permissions
* Users can only query and view carts whose `restriction` value matches one of their authorized restrictions
