In addition to the existing CanMakePaymentEvent.respondWith() event, this feature will add a new method CanMakePaymentEvent.respondWithMinimalUI() that the payment handler could choose to use. Motivation Provide a golden path, low friction experience for users that are enrolled with payment handlers that support a minimal UI. Risks

Compatibility: Low risk, because this is a new feature. Firefox: No public signals Edge: No public signals Safari: No public signals Web developers: Positive

Debuggability The Can Make Payment event and response can be logged in the developer tools. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? No, only supported on Android initially. Eventually it will be supported on all platforms. Is this feature fully tested by web-platform-tests? Not yet.
