Configuration

In order to be implemented in Kogno, the commands must be created first in Telegram through the BotFather or well, by defining them in the configuration file config/platforms/telegram.rb by modifying config.telegram.commands field.

 config.telegram.commands = [
    {
      scope: :default,
      commands:{
        start: "Start chat",
        featured_products: "List featured products."
      }
    },
    {
      scope: :all_chat_administrators,
      commands:{
        update_products: "Update products from server.",
        purchase_count: "Sales today."
      }
    }

  ]

Available scopes are: :default, :all_private_chats, :all_group_chats and :all_chat_administrators. Read more about Commands Scopes on Telegram.
