PaymentRequest.prototype.id

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The id read-only attribute of the PaymentRequest interface returns a unique identifier for a particular PaymentRequest instance.

When constructing an instance of the PaymentRequest, you are able to supply an custom id. If none is provided, the browser automatically sets the id value to a UUID.

Example

This example shows how to give a PaymentRequest instance a custom id.

const details = {
  id: "super-store-order-123-12312",
  total: {
    label: "Total due",
    amount: { currency: "USD", value: "65.00" },
  },
};
const request = new PaymentRequest(methodData, details);
console.log(request.id); // super-store-order-123-12312

The id is then also available in the PaymentResponse returned from the show() method, but under the requestId attribute.

const response = await request.show();
console.log(response.requestId === request.id);

// And in serialized form too
const json = response.toJSON();
console.log(json.requestId,response.requestId, request.id);

Syntax

var id = paymentRequest.id

Value

A DOMString.
