How to Set Up a Telegram Webhook with Python?

Estimated read time 2 min read

To set up a Telegram webhook with Python, you can follow these steps:

  1. Create a Telegram bot by following the instructions provided by Telegram. You will receive a token for your bot.
  2. Decide on a URL where your webhook will receive updates from Telegram. This URL should be publicly accessible over the internet, and it should support HTTPS.
  3. Create a Flask app in Python, which will listen for incoming updates from Telegram.
  4. Install the following packages: flask, requests, and json.
  5. Set up a route in your Flask app to handle incoming updates from Telegram. This route should accept a POST request with a JSON payload.
  6. Extract the relevant data from the JSON payload, such as the chat ID and the message text.
  7. Use the requests package to send a message back to Telegram using the bot token and chat ID.
  8. Use the json package to serialize your response into JSON format.
  9. Use the requests package again to send the serialized JSON response back to Telegram, using the sendMessage method.

Here is some sample code to get you started:

from flask import Flask, request
import requests
import json

app = Flask(__name__)

# Replace this with your bot token
TOKEN = 'YOUR_BOT_TOKEN_HERE'

# Replace this with your webhook URL
WEBHOOK_URL = 'https://your-webhook-url.com/telegram'

@app.route('/telegram', methods=['POST'])
def telegram_webhook():
    update = request.get_json()
    chat_id = update['message']['chat']['id']
    message_text = update['message']['text']
    response_text = 'You said: ' + message_text
    send_message(chat_id, response_text)
    return 'OK'

def send_message(chat_id, text):
    url = 'https://api.telegram.org/bot{}/sendMessage'.format(TOKEN)
    payload = {'chat_id': chat_id, 'text': text}
    headers = {'content-type': 'application/json'}
    response = requests.post(url, data=json.dumps(payload), headers=headers)
    return response.json()

if __name__ == '__main__':
    app.run(port=80)

In this example, we are creating a Flask app that listens on port 80 for incoming requests. The /telegram route is set up to handle POST requests with a JSON payload. We extract the chat ID and message text from the payload, send a response back to the user using the send_message function, and then return an ‘OK’ response to Telegram.

Note that this is just a basic example to get you started. You will likely need to modify this code to suit your specific needs, such as handling different types of Telegram updates or integrating with other APIs.
