List the carts to choose from at sign-in

post

https://apis.kentro.live/store/v1/cart.choices

When a visitor with a guest cart signs in, the guest cart and the account cart both exist; until the buyer chooses, cart writes are refused with CART_CHOICE_REQUIRED. Lists both (items, whether a cart is retained from an earlier choice or still processing a checkout). Send both tokens. The body is empty.

Who may call it: A guest (X-Storefront-Guest) or a signed-in buyer (X-Storefront-Buyer); without either the answer is 401 UNAUTHORIZED.

Headers

X-Storefront-Host

string

required

length between 1 and 253

The published storefront host the request serves (shop.example.com, lower case). It must belong to the tenant of the API key; 404 NOT_FOUND when no published storefront answers it, 403 FORBIDDEN when it belongs to another account.

X-Storefront-Buyer

string

The signed-in buyer's access token (accessToken from POST https://apis.kentro.live/auth/login/customer). Absent for a guest or an anonymous visitor.

X-Storefront-Guest

string

The guest token session.guest answered, which identifies a guest cart and a guest checkout. Send it along with X-Storefront-Buyer at sign-in so the buyer can choose between the guest cart and the account cart.

X-Storefront-Client-Ip

string

The end buyer's IP address as your storefront server saw it. Used for per-visitor limits (search typeahead, sign-up); without it the limits apply to your server.

X-Expected-Portal

string

The store id (store.get answers id) your page was rendered for. When the host now resolves to another store the answer is 409 CONFLICT, so a stale page never acts on the wrong store.

X-Expected-Buyer

string

The identity your page was rendered for: the buyer id, guest:<guestId> for a guest, or guest for an anonymous visitor. A mismatch with the tokens sent is 409 CONFLICT, so a stale page never acts for the wrong buyer.

Responses

200The guest and account carts.
