/**
 * A PaymentIntent guides you through the process of collecting a payment from your
 * customer. We recommend that you create exactly one PaymentIntent for each order
 * or customer session in your system. You can reference the PaymentIntent later to
 * see the history of payment attempts for a particular session.
 *
 * A PaymentIntent transitions through <a
 * href="https://stripe.com/docs/payments/intents#intent-statuses">multiple
 * statuses</a> throughout its lifetime as it interfaces with Stripe.js to perform
 * authentication flows and ultimately creates at most one successful charge.
 *
 * Related guide: <a
 * href="https://stripe.com/docs/payments/payment-intents">Payment Intents API</a>.
 *

The minimum amount is $0.50 US or <a href="https://stripe.com/docs/currencies#minimum-and-maximum-charge-amounts">equivalent in charge currency</a>. The amount value supports up to eight digits (e.g., a value of 99999999 for a USD charge of $999,999.99).
