The Payment Request API defines a consistent user experience across payment methods, payment systems, platforms, and merchants. It is not a new payment method; rather, it is a conduit from the user's preferred payment method to a merchant.
Payment Request Concepts and Usage
Many problems related to online purchase abandonment can be traced to checkout forms, which are user-intensive, difficult to use, slow to load and refresh, and require multiple steps to complete. The Payment Request API is a system that is meant to eliminate checkout forms. It vastly improves user workflow during the purchase process, providing a more consistent user experience and enabling web merchants to easily leverage disparate payment methods.
To request a payment, a web page creates a PaymentRequest object in response to a user action that initiates a payment, such as clicking a "Purchase" button. The PaymentRequest allows the web page to exchange information with the user agent while the user provides input to complete the transaction.
- Manages the process of a user making a payment.
- Enables the web page to update the details of the payment request in response to a user action.
- Returned after a user selects a payment method and approves a payment request.
- Stores address information.
