# 2025-10-30: Cart Service - quoteId added

## Overview

New attribute added to cart:

* `quoteId` - this field contains the ID of the quote associated with the cart

When a quote is created from a cart using the [Creating a quote](https://developer.emporix.io/api-references/api-guides/quotes/quote/api-reference/quote-management#post-quote-tenant-quotes) endpoint, the cart is automatically closed and the `quoteId` is set on that cart. This ensures proper traceability between carts and their corresponding quotes.
