A step-by-step tutorial on how to create a chatbot for Telegram that can download videos from websites like YouTube.
We'll be using Python and a popular library called python-telegram-bot
to build the chatbot. Let's get started!
Step 1: Set Up a Telegram Bot
- Open Telegram and search for the "BotFather" bot.
- Start a chat with the BotFather and follow the instructions to create a new bot.
- Once your bot is created, you will receive an API token. Save this token as you'll need it later.
Step 2: Set Up Your Development Environment
- Install Python on your computer if you haven't already. You can download it from the official Python website (python.org).
- Choose a code editor for Python. Some popular options are Visual Studio Code, PyCharm, or Sublime Text. Install your preferred editor.
Step 3: Install the Required Libraries
- Open a terminal or command prompt and run the following command to install the
python-telegram-bot
library:
pip install python-telegram-bot youtube_dl
Step 4: Create a New Python Script
- Open your code editor and create a new Python script. You can name it
telegram_video_downloader.py
or choose any name you prefer.
Step 5: Import the Required Libraries
- Add the following lines at the beginning of your Python script to import the necessary libraries:
import logging
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
import youtube_dl
Step 6: Set Up Logging
- Add the following lines of code to enable logging in your script. This will help you debug any issues that may occur:
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
level=logging.INFO)
logger = logging.getLogger(__name__)
Step 7: Define a Function to Handle the /start
Command
- Add the following code to define a function that will handle the
/start
command when it is received by the bot:
def start(update, context):
context.bot.send_message(chat_id=update.effective_chat.id, text="Hello! I'm a video downloader bot. Just send me the URL of the video you want to download.")
Step 8: Define a Function to Handle Video Downloads
- Add the following code to define a function that will handle the video download functionality:
def download_video(update, context):
url = update.message.text
ydl_opts = {
'outtmpl': '%(title)s.%(ext)s', # Output file name template
'format': 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best',
}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
try:
info = ydl.extract_info(url, download=False)
video_title = info['title']
video_url = info['url']
ydl.download([url])
context.bot.send_message(chat_id=update.effective_chat.id, text="Video downloaded successfully!")
context.bot.send_video(chat_id=update.effective_chat.id, video=video_url, caption=video_title)
except Exception as e:
logger.error(f"Error downloading video: {e}")
context.bot.send_message(chat_id=update.effective_chat.id, text="Failed to download the video.")
Step 9: Set Up the Main Function
- Add the following code to set up the main function that will run the bot:
def main():
updater = Updater(token='YOUR_API_TOKEN', use_context=True)
dispatcher = updater.dispatcher
dispatcher.add_handler(CommandHandler("start", start))
dispatcher.add_handler(MessageHandler(Filters.text & ~Filters.command, download_video))
updater.start_polling()
updater.idle()
Step 10: Run the Bot
- Replace
'YOUR_API_TOKEN'
in themain()
function with the API token you received from the BotFather in Step 1. - Add the following code at the bottom of your script to run the bot:
if __name__ == '__main__':
main()
Step 11: Test Your Bot
- Save the Python script and run it from your terminal or command prompt using the command:
python telegram_video_downloader.py
- Open Telegram and search for the name of your bot.
- Start a chat with your bot, and send it a YouTube video URL.
- The bot should respond with a message indicating that the video has been downloaded successfully.
Your bot's full code should look like this:
import logging
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
import youtube_dl
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
level=logging.INFO)
logger = logging.getLogger(__name__)
def start(update, context):
context.bot.send_message(chat_id=update.effective_chat.id, text="Hello! I'm a video downloader bot. Just send me the URL of the video you want to download.")
def download_video(update, context):
url = update.message.text
ydl_opts = {
'outtmpl': '%(title)s.%(ext)s',
'format': 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best',
}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
try:
info = ydl.extract_info(url, download=False)
video_title = info['title']
video_url = info['url']
ydl.download([url])
context.bot.send_message(chat_id=update.effective_chat.id, text="Video downloaded successfully!")
context.bot.send_video(chat_id=update.effective_chat.id, video=video_url, caption=video_title)
except Exception as e:
logger.error(f"Error downloading video: {e}")
context.bot.send_message(chat_id=update.effective_chat.id, text="Failed to download the video.")
def main():
updater = Updater(token='YOUR_API_TOKEN', use_context=True)
dispatcher = updater.dispatcher
dispatcher.add_handler(CommandHandler("start", start))
dispatcher.add_handler(MessageHandler(Filters.text & ~Filters.command, download_video))
updater.start_polling()
updater.idle()
if __name__ == '__main__':
main()
Remember to replace 'YOUR_API_TOKEN'
in the main()
function with the API token you received from the BotFather.

First of all, thanks for the information.
I have a question; The code works for any video site, for example ok.ru?.
