The button variables control the presentation in the flow and the information that is provided
to the buyer initially. Because the URL is associated with a Hosted Solution token, the URL is
usable for approximately two hours after it is created or until the payment is successful.
Using Form POST
Identify the WEBSITECODE in the response and use the code to create a Pay Now button on
your review page. When your buyer clicks the button, they are redirected to the PayPal hosted
payment page. Like the URL, the button is usable for approximately two hours or until the
payment is successful.
