Facebook Messenger Bot

• Tell people that you are busy at the momment or having internet connection problems even when you are offline :)
• Customizable message and duration
• Support Facebook 2-factors authentication only
• Run on cloud platform -> you can turn on anywhere, anytime
• Using Dialogflow SmallTalk feature, sender can chat with this bot instead of just leaving a message :)

This guide is for Heroku only, other platforms may follow the same process

1. 3rd parties

• Dialogflow:

  • Enable Small Talk feature and get an API key

  • Create server/utils/apiaiConfig.js:

     module.exports = 'YOUR_API_KEY';

• Auth0:

  • Create server/utils/auth0Config.js and get these values:

  const AUTH0_JWKS_URI = "";
  const AUTH0_AUDIENCE = "";
  const AUTH0_ISSUER = "";
  const AUTH0_ALGORITHMS = "RS256";
  
  export default { AUTH0_JWKS_URI, AUTH0_AUDIENCE, AUTH0_ISSUER, AUTH0_ALGORITHMS }

2. Server setup

• Install postgres add-ons for your Heroku project
• Setup database using content in db.sql
• Add your account to database:

insert into Accounts (email, password) values ('YOUR_EMAIL', 'YOUR_PASSWORD');

Your Facebook account must have 2 factors authentication enabled

3. Build Setup

• Create .env with 1 line: BOT_URL=https://[YOUR_BOT_URL].herokuapp.com
• Open server/routes/index.js and comment as guided in line 10 and line 34
• Install dependencies and build file:

npm install
npm run build

• Copy /build, package.json, package-lock.json to Heroku project folder (Heroku only needs these things)
• Push to Heroku

4. Using bot

• Use bot-manager app :)
• Or simply send an api containing authentication header (Bearer 'access_token') + data required to a specific route
