After registering your Bot with BotFather in Telegram (Here's a link on how to do it) , you will be provided the Bot Token.

You can use it directly in OR you can also save it in a .env file and load it from the environment variable and then use it like this.

TOKEN = "your token here"
    OR
TOKEN = os.getenv('BOT_TOKEN') #loading from .env file

bot = telebot.TeleBot(token=TOKEN)

After that you can configure the commands depending on what you want to do.

@bot.message_handler(commands=['your_command_name_here']) 
def send_welcome(message):
    bot.reply_to(message, 'Welcome to our bot.. ')

This is a simple example on how you can reply when a particular command is selected on the Bot. For more options you can check pyTelegramBotAPI

The code in Bot.py is written to Start and Stop an Azure Virtual Machine using an private API whose URL are also stored in .env file and then called via the requests library in Python. It's done in 3 steps

1. It checks whether the user who is trying to start or stop the server is whether authorised or not to do so and replies accoridngly to the user if not authorised.
2. It checks the current status of the Azure' VM and if it's the opposite then it calls the private URL to turn on or off the server.
3. If first two steps are validated then it sends a message to user that it is trying to Start/Stop the server and it may take some time.
4. On successfull response from the API then it replies to the user that the task has been completed.
