How to integrate Telegram Bot with Python using requests

A simple project using requests in python to send/receive the message from the Bot.

Starting with a simple intro of Telegram and Python

Telegram is a cross-platform cloud-based instant messaging, video calling, and VoIP service.

Python is an interpreted, high-level and general-purpose programming language. Python’s design philosophy emphasizes code readability with its notable use of significant whitespace.

Lets start with the creating a Bot

• Now open Telegram App and search for BotFather and open it

• Now click on start and you will get a details information and commands for creating bot, deleting bot and etc …

• Type or select /newbot to create a bot
• Now it will send you a message, that to choose a name for your bot and type your own bot name (Eg: chat,chitti,Alex)
• Now it will ask you to enter the username for your bot with the given condition like Alex_bot or Chat_bot or AlexBot
• If the username is already take try it using different name but it should satisfy the condition
• When it accept your username it will send you a API token key like

142523231:AEX************

• In that message at top you will see a link like t.me/AlexBot this will redirect to your bot chat, then click on /start to start chat with the bot

Let’s start coding

• Create a empty python file and name it any thing (Eg: TeleBot.py)
• import the required modules

import request as req

• Now create a two variables

Url = ''
Key = ''

• For Url add https://api.telegram.org/bot and for Key add the API Token from the BotFather

• Lets try to get the bot information using requests

def BotInfo():
    res = req.get(Url+Key+'/GetMe')
    result = res.json()
    print(['FirstName '+result['result']['first_name'],"Username "+result['result']['username'])
BotInfo()

• This will give like FirstName Alex, Username AlexBot

Lets try in the web browser

• Open a new Browser and type the https://api.telegram.org/bot+Key+/GetMe here the Key is API Token and /GetMe used to get the information of the Bot

• Getting the queries where user asked to bot and here /GetUdpates will give a queries https://api.telegram.org/bot+Key+/getUpdates

• Here in this Json file text is the query from the user asked to bot

Lets start coding!

• Open the python file which you have created (Eg: TeleBot.py )
• Lets send a message to user from bot
• When we sending a message to user we need to get the id of the user

def UserId():
    res = req.get(Url+Key+'/GetUpdates')
    result = res.json()
    result = result['result'][len(result['result'])-1] # To get the latest message id
    return result['message']['from']['id']

def Sendmessage(answer):
    id = UserId()
    pos = {"chat_id":id,"text":answer}
    res = req.post(Url+Key+"/sendmessage",data=pos)
Sendmessage("Hello")

• Here /sendmessage is to send message of type json with chat_id and text
• Now you will see a message in telegram from bot
• Enjoy playing with it.
