In Telegraf, it is possible to call all the possible api methods using bot.telegram.*
* here refers to methodName
Telegraf sends request to Bot API and Telegraf supports all the methods available for Bot API.
Bot API further calls the MtProto Server to send that request to Telegram's Servers.
MtProto contains more methods and data than Bot API.
Note: Telegraf only Supports Bot API and its methods.
