The Payment Request API requires that merchants supply a list of identifiers for supported payment methods. This document defines those identifier strings and how they are created.
- Web API
This specification describes a web API to allow merchants (i.e. web sites selling physical or digital goods) to easily accept payments from different payment methods with minimal integration. User agents (e.g. browsers) will facilitate the payment flow between merchant and user.
- Web API
The Payment Request API provides a standard way to initiate payment requests from Web pages and applications. User agents implementing that API prompt the user to select a way to handle the payment request, after which the user agent returns a payment response to the originating site. This specification defines capabilities that enable Web applications to handle payment requests.
This specification defines the machine-readable manifest file, known as a payment method manifest, describing how a payment method participates in the Web Payments ecosystem, and how such files are to be used.
The Basic Card Payment specification describes the data formats used by the PaymentRequest API to support payment by payment cards such as credit or debit cards.
