In this chapter you learned how the actors in your app's payment authorization workflow work together to help the user provide the information you need to process the payment and order (if the payment is approved by the payment card's issuing bank). The chapter showed how to prepare the payment request with essential payment information, such as the payment networks you support. It described how to respond to changes the user makes to the order in the payment sheet. Finally, the chapter showed how to dismiss the payment sheet after the user authorizes or cancels the payment request.
The next chapter will describe the payment processing workflow, which is where you will process the information obtained here to process the payment through your payment gateway and fulfill the customer's order in your order processing web application. We will consider the payment information required to get the user's payment card's issuing bank to approve the transaction.
