Hi @sshadmand! Thanks for the port. What would be the equivalent of requests.post('https://graph.facebook.com/v2.6/me/messages', json=json_data, params=params) if I were to use urllib/urllib2?

Hey, I'm sorry for the following noob question. How would I set up the url to access this file? What is the webhook URL you would provide at the Facebook Messenger Dashboard to connect this endpoint? Please bear with my ignorance, I don't have any experience with web based python applications.
