The PaymentMethodChangeEvent interface of the Payment Request API describes the paymentmethodchange event which is fired by some payment handlers when the user switches payment instruments (e.g., a user selects a "store" card to make a purchase while using Apple Pay).

PaymentMethodChangeEvent()

Creates and returns a new PaymentMethodChangeEvent object, optionally initialized with values taken from a given PaymentMethodChangeEventInit dictionary.

In addition to the properties below, this interface includes properties inherited from PaymentRequestUpdateEvent.

methodDetails Read only Secure context

An object containing payment method-specific data useful when handling a payment method change. If no such information is available, this value is null.

methodName Read only Secure context

A string containing the payment method identifier, a string which uniquely identifies a particular payment method. This identifier is usually a URL used during the payment process, but may be a standardized non-URL string as well, such as basic-card. The default value is the empty string, "".
