How to Create a Telegram Filter Script from Scratch

Getting Started with Telegram Filter Scripts

Creating a Telegram filter script from scratch might sound like a daunting task, but it's actually quite fun! Let's dive into the basics of how you can get started.

Understanding the Basics

First things first, you need to know the basic structure of a Telegram bot. You'll be using the Telegram Bot API to interact with Telegram servers. The API allows you to send and receive messages, manage groups, and much more.

Setting Up Your Environment

You'll need a few tools to get started:

• Python: We'll be using Python for this tutorial. If you don't have it installed yet, you can download it from the official Python website.
• Telegram Bot Token: You'll need to create a new bot on Telegram and get the token. Simply message BotFather on Telegram, follow the instructions, and you'll have your token in no time!
• Requests Library: This Python library will help you make HTTP requests to the Telegram API. Install it using pip: pip install requests.

Creating Your Script

Let's start by creating a simple script to filter messages. Open your favorite code editor and create a new Python file.

Step 1: Import Libraries

First, you'll need to import the necessary libraries.

import requests
import time

Step 2: Define Your Bot Token and URL

Next, define your bot token and the base URL for the API.

BOT_TOKEN = 'YOUR_BOT_TOKEN_HERE'
BASE_URL = f'https://api.telegram.org/bot{BOT_TOKEN}/'

Step 3: Get Updates

Create a function to get updates from Telegram.

def get_updates():
    url = BASE_URL + 'getUpdates'
    response = requests.get(url)
    return response.json()

Step 4: Filter Messages

Now, let's create a function to filter messages containing a specific keyword.

def filter_messages(updates, keyword):
    for update in updates['result']:
        message = update.get('message', {}).get('text', '')
        if keyword in message:
            print(f"Filtered Message: {message}")

Step 5: Run Your Script

Finally, write the main loop to keep the script running and filtering messages.

def main():
    keyword = 'hello'
    while True:
        updates = get_updates()
        filter_messages(updates, keyword)
        time.sleep(2)

if __name__ == '__main__':
    main()

Testing Your Script

Run your script by executing python your_script_name.py. Send a message containing the keyword "hello" to your bot, and you should see the filtered message printed in your terminal.

Adding More Features

Once you have the basics down, you can add more features to your script:

• Responding to Messages: You can make your bot respond to filtered messages by sending a reply using the sendMessage API method.
• Advanced Filtering: Implement more complex filtering logic, such as filtering based on user roles or message types.
• Logging: Add logging to keep track of filtered messages and bot activity.

Conclusion

And there you have it! You've created a basic Telegram filter script from scratch. With some creativity, you can expand this script to build a powerful bot tailored to your needs. Happy coding! 😊
