A simple DialogFlow Express fulfillment app that messes around with entities
It's testable here: https://dialogflow-fulfillment-entities-playground.glitch.me/
The agent's export file is downloadable here: http://bit.ly/2ILgTuv
The fulfillment url is already configured to hit this webhook :)
Try typing something like I want to eat a banana with my dog.
In the agent, I've only made a simple Fruits
entity that is captured in the intent and sent to the fulfillment app.
