{{securecontext_header}}{{APIRef("Payment Request API")}}
The details read-only property of the
{{domxref("PaymentResponse")}} interface returns a JSON-serializable object that
provides a payment method specific message used by the merchant to process the
transaction and determine a successful funds transfer.
An object. This data is returned by the payment app that satisfies the payment request. Developers need to consult whomever controls the URL for the expected shape of the details object.
The following example extracts the details from the {{domxref('PaymentResponse')}} object to the promise returned from {{domxref('PaymentRequest.show()')}}. In a real-world implementation this data would then be sent to a payment server.
payment.show().then((paymentResponse) => {
const paymentData = {
// payment method string
method: paymentResponse.methodName,
// payment details as you requested
details: paymentResponse.details,
// shipping address information
address: toDict(paymentResponse.shippingAddress),
};
// Send information to the server
});
