Check a checkout token against a member-bound cart (our checkout only)
Answers whether a checkout token from POST /api/member/checkout-session opens a member-bound cart: the token must have been issued for this store, this cart and the cart’s member_key. For our hosted checkout only: its BFF calls it over a service binding, and any call over this public URL is refused with 403 (code: CART_ACCESS_INTERNAL_ONLY).
Headers

You receive the value once your Entria backend has been created and configured. Missing header returns 400; an unknown store returns 404.
