Hello, I'm working on a single-product website for a client. My client has requested that the entirety of the payment process all reside on one page. For example, the user clicks "Add to cart" and then they are immediately sent to a page containing the shipping/billing information and payment gateway form, all on one page.
Currently, the payment gateway only reveals itself once you're on the Checkout -> Pay page. Is there a way to show the form without the use of a redirect or key variable?
