/**
 * This sample builds an HTML form to simulate the checkout page of an e-commerce platform.
 * A click on the "Proceed to Afterpay" button posts to the current page, which calls the "Create Checkout" API
 * (satisfying only the bare minimum technical requirements) and then (in the event of success) redirects to
 * the Afterpay Checkout URL. If you navigate through the consumer payment flow and click "confirm" to commit
 * to the payment schedule, you should return to this page with new query parameters appended to the URL.
 * The "orderToken" parameter will then be used to submit an "Immediate Payment Capture" Request. Some of the
 * important components of the Response will then be rendered above the HTML form.
