Secure context
This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The Payment Request API provides a consistent user experience for both merchants and users. It is not a new way for paying for things; rather, it's a way for users to select their preferred way of paying for things, and make that information available to a merchant.

Payment Request concepts and usage

Many problems related to online shopping-cart abandonment can be traced to checkout forms, which can be difficult and time consuming to fill out and often require multiple steps to complete. The Payment Request API is meant to reduce the number of steps needed to complete a payment online, potentially doing away with checkout forms. It aims to make the checkout process easier, by remembering a user's details, which are then passed along to a merchant hopefully without requiring a HTML form.

Advantages of using the Payment Request API with "basic-card" (card-based payments):

  • Fast purchase experience: Users enter their details once into the browser and are then ready to pay for goods and services on the web. They no longer have to fill out the same details repeatedly across different sites.
  • Consistent experience on every site (that supports the API): As the payment sheet is controlled by the browser, it can tailor the experience to the user. This can include localizing the UI into the user's preferred language.
  • Accessibility: As the browser controls the input elements of the payment sheet, it can assure consistent keyboard and screen reader accessibility on every website without developers needing to do anything. A browser could also adjust the font size or color contrast of the payment sheet, making it more comfortable for the user to make a payment.
  • Credentials management: Users can manage their credit cards and shipping addresses directly in the browser. A browser can also sync these "credentials" across devices, making it easy for users to jump from desktop to mobile and back again when buying things.
  • Consistent error handling: The browser can check the validity of card numbers, and can tell the user if a card has expired (or is about to expire). The browser can automatically suggest which card to use based on past usage patterns or restrictions from the merchant (e.g, "we only accept Visa or Mastercard"), or allow the user to say which is their default/favorite card.

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.

You can find a complete guide in Using the Payment Request API.

Note: The API is available inside cross-origin <iframe> elements only if they have had the allowpaymentrequest attribute set on them.

Interfaces

PaymentAddress
An object that contains address information; used for billing and shipping addresses, for example.
PaymentRequest
An object that provides the API for creating and managing the user agent's payment interface.
PaymentRequestEvent
An event delivered to a payment handler when a PaymentRequest is made.
PaymentRequestUpdateEvent
Enables the web page to update the details of the payment request in response to a user action.
PaymentMethodChangeEvent
Represents the user changing payment instrument (e.g., switching from a credit card to debit card).
PaymentResponse
An object returned after the user selects a payment method and approves a payment request.
MerchantValidationEvent
Represents the browser requiring the merchant (website) to validate themselves as allowed to use a particular payment handler (e.g., registered as allowed to use Apple Pay).

PayerErrors
A dictionary containing strings providing descriptive explanations of any errors in related to PaymentResponse's email, phone, and name attributes.
PaymentDetailsUpdate
An object describing changes that need to be made to the payment details in the event that the server needs to update information following the instantiation of the payment interface but before the user begins to interact with it.
BasicCardChangeDetails
An object providing redacted address information that is provided as the methodDetails on the paymentmethodchange event sent to the PaymentRequest when the user changes payment information.
BasicCardErrors
An object providing any error messages associated with the fields in the BasicCardResponse object that are not valid. This is used as the value of the paymentMethod property on the PaymentValidationErrors object sent to the PaymentRequest when an error occurs.
