Implementation of DialogFlow API.AI with JCubic Terminal Emulator

This is a fairly simple request. I need to connect a simple website based on [login to view URL] with [login to view URL]'s DialogFlow (webhook fulfillment). I am struggling to do so even though I managed to link JCubic with Cleverbot Chatbot via JSON AJAX responses. I don't need management of the bot itself, just making the basic link of communication between my server with simple JS code and the DialogFlow API.
