PaymentRequest.prototype.id

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 via  PaymentDetailsInit dictionary's id member. 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.
