# Cart

The [Carts](https://www.digitalriver.com/docs/commerce-shopper-api/#tag/Apply-Shopper) resource is an essential tool designed to facilitate customers' and developers' management of shopping cart operations. It allows for retrieving, updating, and modifying cart data, ensuring a seamless shopping experience. By integrating with our Carts API, you can handle cart contents efficiently, whether for viewing a customer's current cart items, updating quantities, or adding and removing products.

Note that interaction with this API requires either an anonymous token for limited access or an authenticated token for full access, ensuring secure and controlled modifications to cart data.
