To be clear, this is also possible via URL-based callbacks, you can relay messages using that mechanism, but it forces Web developers to initiate a payment at one location and complete it at another location (which is done today, but it's not as nice as just waiting for a promise to be fulfilled). Note that this second approach is sort of what the HTTP API uses (because that sort of programming paradigm is more common place in non-browser HTTP clients):
