Facebook Page Creation

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.

Facebook App Creation

• Add a new app at https://developers.facebook.com/quickstarts/?platform=web. Name it and click "Create New Facebook App ID":

• Add email, select category, an add web site. (Any URL is OK):

Facebook Messenger Setting

• From https://developers.facebook.com/apps/, select the created app:

• Select Messenger and get started:

• Select the page you have created and get the Page Access Token:

Launch Server in Heroku

• Run heroku create and push to heroku:

cd Indian-rail-fb-chatbot
heroku create
git push heroku master

Facebook Webhooks Setting

• The final step is to put this server URL in the Facebook app setting. From https://developers.facebook.com/apps/, select your app and messenger. You will see Webhooks:

• 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://irctcfbweb.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.

• Then, you will see the green complete!

• You may need to select the Facebook Page one more time and get the access token.

• You need to fire this command to activate your messanger.

curl -X POST "https://graph.facebook.com/v2.6/me/subscribed_apps?access_token=<PAGE_ACCESS_TOKEN>"

• You may see:

{"success":true}

• Finally, go to the Facebook page you created/selected, and talk to your bot. Enjoy!
