The project is kind of a webhook bot to communicate with API.AI (https://api.ai/), rebranded as Dialogflow.
It opens a http server at the /webhook endpoint (as in documentation), then assign a handler here, then just uses some simple abstraction to route different actions.
I probably also want to add that I used NGrok (https://ngrok.com/) to port my local http server to a public server (because API.AI don't provide tools for localhost testing).
