Telegram Link Resolver

A Python script to resolve Telegram invite links (t.me URLs) to their corresponding channel IDs. This is useful for collecting channel IDs for further analysis or monitoring.

Requirements

• Python 3.7+
• A Telegram account
• Telegram API credentials (instructions below)

Setup Instructions

1. Install required packages:

   pip install telethon python-dotenv

2. Get Telegram API Credentials:

   • Visit https://my.telegram.org/apps and log in with your Telegram account
   • Create a new application if you don't have one already
   • You'll receive an API_ID (numbers) and API_HASH (alphanumeric string)
   • Keep these credentials secure and never share them publicly!

3. Create a .env file:

   Create a file named .env in the same directory as the script with the following content:

   API_ID=your_api_id_here
   API_HASH=your_api_hash_here
   

   Replace your_api_id_here and your_api_hash_here with the credentials you obtained in step 2.

4. Create a links file:

   Create a text file containing the Telegram invite links you want to resolve, one per line. For example:

   https://t.me/channel_name
   https://t.me/joinchat/INVITE_CODE
   

Usage

Run the script using Python:

python telegram_link_resolver.py path_to_links_file.txt

First Run Authentication

The first time you run the script, you'll need to authenticate with your Telegram account:

1. The script will prompt you to enter your phone number with country code (e.g., +1234567890)
2. Telegram will send a verification code to your Telegram app
3. Enter this code when prompted by the script

After successful authentication, a session file will be created, and you won't need to authenticate again unless you delete the session file or run the script from a different location.

Output

The script provides two types of output:

1. Detailed results showing each link and its corresponding channel ID and title
2. A list of just the channel IDs, which can be redirected to a file if needed

Security Notes

• The session file contains sensitive information. Keep it secure.
• Never share your API credentials or session file with others.
• Consider adding .env and *.session to your .gitignore if using version control.

Troubleshooting

• If you encounter rate limiting errors, increase the delay between requests by modifying the await asyncio.sleep(1) line.
• Some invite links may be expired or invalid, which will result in error messages.
• If you're unable to authenticate, make sure your phone number is entered correctly and that your Telegram account is active.
