# Get Checkout

> Get checkout by ID. Accepts either auth shape:

  * **Storefront token** (`X-Site-ID` + `X-Stella-Token`) — for the
    merchant's own storefront calling back into Stella.
  * **Per-checkout token** (`Authorization: Bearer chk_…`) — for
    the Stella-hosted `checkout-web` SPA which runs on a different
    origin and doesn't carry the merchant's storefront token.

The `chk_…` Bearer is preferred when present because it carries
the eager-loaded checkout already (saves a query) and binds the
request to one specific checkout (defense in depth on top of the
URL `checkout_id`).
