In the examples shown in this article, we did no customization on our end and used everything as is. Beyond the scope of this article, we can also customize UCP, so that it can be integrated into corporate web portals.
In ACS we can use Web Services Description Language (WDSL) to integrate UCP. The WSDL is an XML format that describes network services as a collection of ports that operate on messages. WSDL is extensible to allow the description of endpoints and their messages regardless of the message formats or network protocols that you use.
