Get the current state of a cart
Reads back a cart’s lines, totals and checkoutUrl by id. Use it to re-render the basket on load, or to restore a returning shopper’s basket from a saved cart id. It only reads the cart — it never adds, removes or re-prices items.
Headers
x-entria
Identifies which store this request is for. Required on every store-scoped route. It is not authentication and not a secret — it grants no privileges and is safe to send from a browser. You receive the value once your Entria backend has been created and configured. Missing header returns 400; an unknown store returns 404.
Query parameters

The id returned when the cart was created.
Response
The cart as it currently stands, including its items, totals and checkoutUrl.
