The paymentrequest
event of the ServiceWorkerGlobalScope
interface is fired on a payment app when a payment flow has been initiated on the merchant website via the PaymentRequest.show()
method.
Use the event name in methods like addEventListener()
, or set an event handler property.
addEventListener("paymentrequest", (event) => {});
onpaymentrequest = (event) => {};
When the PaymentRequest.show()
method is invoked, a paymentrequest
event is fired on the service worker of the payment app. This event is listened for inside the payment app's service worker to begin the next stage of the payment process.
let payment_request_event;
let resolver;
let client;
self.addEventListener("paymentrequest", async (e) => {
if (payment_request_event) {
resolver.reject();
}
payment_request_event = e;
});
When a paymentrequest
event is received, the payment app can open a payment handler window by calling PaymentRequestEvent.openWindow()
. The payment handler window will present the customers with a payment app interface where they can authenticate, choose shipping address and options, and authorize the payment.
When the payment has been handled, PaymentRequestEvent.respondWith()
is used to pass the payment result back to the merchant website.
See Receive a payment request event from the merchant for more details of this stage.
