Hmm I had some experience with Telegram bots. So if the case is that you just need the notification about new message to the stdout of the command line, I would suggest Telethon library. It acts as usual client, therefore it's not a bot and you don't have to register it at BotFather. Yet you'll have to create an application for https://my.telegram.org/apps and get credentials from there. Also check out unofficial CLI tool: https://github.com/vysheng/tg/
