How do I convert an html page to a pdf using the APIs in Acrobat XI?

I am creating a c# program that needs to loop through a list of URLs, open each as an html page and save it as pdf.  I see it is possible to save an html page as a pdf using the plug-in in XI but I'm wondering how to do this from an application using the APIs.  Can someone point me in the right direction? 

Thanks!
