nl: SessionsA Checkout Session represents your customer's session as they pay for
  one-time purchases or subscriptions through Checkout
  or Payment Links. 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 Customer, and either the successful
  PaymentIntent or an active
  Subscription.You can create a Checkout Session on your server and pass its ID to the
  client to begin Checkout.
