/**
 * 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>
 * or <a href="https://stripe.com/docs/payments/payment-links">Payment Links</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 redirect to its URL
 * to begin Checkout.
