The PaymentRequestEvent constructor creates a new PaymentRequestEvent object instance.

type

A string with the name of the event. It is case-sensitive and browsers set it to paymentrequest.

options Optional

An object that, in addition of the properties defined in ExtendableEvent(), can have the following properties:

methodData

An array of PaymentMethodData objects (see methodData > Value) containing payment method identifiers for the payment methods that the website accepts and any associated payment method-specific data.

modifiers

An array of objects containing changes to payment details.

paymentRequestId

The ID of the PaymentRequest object.

paymentRequestOrigin

The origin where the PaymentRequest object was initialized.

topOrigin

The top-level origin where the PaymentRequest object was initialized.

total

The total amount being requested for payment.

A new PaymentRequestEvent object.

A developer would not use this constructor manually. A new PaymentRequestEvent object is constructed when a handler is invoked as a result of the paymentrequest event firing.

self.addEventListener("paymentrequest", (e) => {
  // ...
});
