/**
 * A Checkout Session represents your customer's session as they pay for one-time
 * purchases or subscriptions through <a
 * href="https://stripe.com/docs/payments/checkout">Checkout</a>. We recommend
 * creating a new Session each time your customer attempts to pay.
 *
 * Once payment is successful, the Checkout Session will contain a reference to the
 * <a href="https://stripe.com/docs/api/customers">Customer</a>, and either the
 * successful <a
 * href="https://stripe.com/docs/api/payment_intents">PaymentIntent</a> or an
 * active <a href="https://stripe.com/docs/api/subscriptions">Subscription</a>.
 *
 * You can create a Checkout Session on your server and pass its ID to the client
 * to begin Checkout.
 *
 * Related guide: <a href="https://stripe.com/docs/payments/checkout/api">Checkout
 * Server Quickstart</a>.
