I guess you are talking about Big Smoke assignment, payment authorization is supported by web service as per assignment stated, you are free to make assumptions to draft your solution. However, justify your design decision.... When you say UI integration I assume you need a web page/JSP etc to enter some details, look for any shopping websites (tons available..)which allow you to do guest check out for your cart products and you will get an idea what details normally required. Hope this helps.
