How to create URL for webhook receiver within the script?

Question

I need to connect to a webhook to retrieve data every-time a survey is taken. The tool I am using requires me too pass in a call back url.

Is there anyway I can generate a static URL within my script that can act as my call back url?

I found this receiver script online but this only listens to port 8080:

import web

urls = ('/.*', 'hooks')

app = web.application(urls, globals())

class hooks:
    def POST(self):
        data = web.data()
        print
        print 'DATA RECEIVED:'
        print data
        print
        return 'OK'

if __name__ == '__main__':
    app.run()
