  bobot:
    app_id: "123"
    app_secret: "456"
    verify_token: "your token"
    skip_code: ""
    domains: "whitelisted-domain.com,second-whitelisted-domain.com"
    async: false
    commander_queue_name: "default"
    pages: 
      - slug: "facebook_1"
        language: "fr"
        page_id: "789"
        page_access_token: "abc"
        get_started_payload: "get_started"
        home_url_for_chat_extension: "https://whitelisted-domain.com/messenger_extension"
        size_for_chat_extension: "tall"

Webhook url

Facebook wants an url where he can send me information to communicate with my server.

When you installed Bobot, a line has been added to your config/routes.rb

mount Bobot::Engine => "/XXXXXX", as: "bobot"

You have to setup as url on the webhook facebook interface:
- https://domain.ltd/XXXXXX/facebook

And as :verify_token, the one you set on your config/secrets.yml

Persistent Menu, Greeting Text, Whitelist domains, Get Started

After having define into your `config/application.rb` your I18n.available_locales.

Then, persistent menu and the greeting text will catch the content of them from `locales/bobot.{locale}.yml`
- config/locales/bobot.{locale}.yml

The whitelist domains and get_started button settings have to be set in:
- config/secrets.yml

- `page = Bobot::Page.find(facebook_page_id)`
- `page = Bobot::Page.find_by_slug(facebook_page_slug)`

- `page = Bobot::Page[facebook_page_slug]`

After fetching the page with command above, you have access to:
- `page.update_facebook_setup!`
