#bot api

Require API Token

You need to sign up a telegram account and create a bot with @botfather as the reference link.

You need to add @botfather as ur friend and create a new bot by “/newbot” message. if you need to know all commands, you can use “/” or “/help” to show all commands.

Botfather will ask u to provide a name for your bot, you can name your bot and get the token.

Create Ur Bot by Python

you can get telegram api from https://github.com/python-telegram-bot/python-telegram-bot, install by the command as below.

$ pip install python-telegram-bot --upgrade

There are 2 methods to create connection, webhook or polling updates. I don’t have personal server and domain, so I use polling updates.

The major bot command is “/status“, it will help me to call a function, MediaCount, which will get the media count from mongo. All I need is to keep the service and check the telegram.
