PaymentRequest: id property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
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 a 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.
js
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.
js
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); Value
A string.
