# Add to Cart

The workflow begins when a user adds items to the cart from either the Product Detail Page (PDP) or the Product List Page (PLP). The system then determines whether the user is initiating a new checkout or resuming an existing one and triggers the appropriate logic.

**Endpoint:** POST [`/commerce/carts/{activeCartOrId}/cart-items`](https://developer.salesforce.com/docs/commerce/salesforce-commerce/references/comm-cart-ref?meta=postCartItemCollection)
