Wit.ai and Facebook Messenger Integration Example
Fork this repository and clone.
git clone https://github.com/{forked}/Wit-Facebook.git
cd Wit-Facebook
npm install
Go to https://wit.ai/home and create a wit app for you. Read https://wit.ai/docs/quickstart and see a demo at: https://wit.ai/sungkim/weather/stories. Then, go to the setting in your wit app and get the token id.
Test the bot.js with your WIT_TOKEN, and make sure the bot is working.
$WIT_TOKEN=insert_token_here node bot
You can type your text, and see bot's response.

First you need to make a Facebook Page at https://www.facebook.com/pages/create/?ref_type=pages_browser, since the messenger bot will be connected to your facebook page.
cd Wit-Facebook
heroku create
git push heroku master
Select "Setup Webhooks", and you will see callback URL and verify token. For the callback URL put your Hherokuapp URL + "/webhook". For example, my callback URL is https://fbwitbot.herokuapp.com/webhook.
Type the Verify Token that you set in the Heruku app setting. If you haven't set, the default value is "just_do_it".
Click all items in the Subscription Fields.
curl -X POST "https://graph.facebook.com/v2.6/me/subscribed_apps?access_token=<PAGE_ACCESS_TOKEN>"
{"success":true}
npm test
$WIT_TOKEN=insert_token_here node bot

$WIT_TOKEN=insert_token_here node index
In other shell, fire this command:
$curl -X POST -H "Content-Type: application/json" -d @__tests__/msg.json http://localhost:8445/webhook
You will see something like this:
