Get list of my Telegram channels I'm currently a member

Question

Is there a way to get a list of channels I'm a member of in Telegram (preferably Telegram Desktop)? I may be able to come up with a solution using JS in the browser or even Selenium, but isn't there a more ergonomic approach that would work in Telegram Desktop (like an API)?

If it matters I'm running Telegram as a snap application on Ubuntu 20.04.

Well, the official Telegram Bot API does not have an option to get members of a channel. So using Telegrams MTPROTO to make your own client that will do this is the only legit way of retreiving this data.

As said, you could scrape the Telegram Web Version, but thats most likely to change some time soon which you'll need to edit your scraper.

Telethon seems like a valid/stable solution, continue reading for a custom example script

If you just want to know what channels you're member of, you can use the dialog.entity to check if the current one is of type Channel

1. Use client.iter_dialogs() to loop over each channel
2. Use isinstance to check if it's a Channel
   • This will make sure we don't log for types like:
     • User (chats)
     • ChatForbidden (Chats your kicked out off)

from telethon import TelegramClient
from telethon.tl.types import  Channel

import asyncio

async def main():

    async with TelegramClient('anon', '2234242', 'e40gte4t63636423424325a57') as client:

        # For each dialog
        async for dialog in client.iter_dialogs(limit = None):

            # If this is a Channel
            if isinstance(dialog.entity, ( Channel )):

                # Log
                dialogType = type(dialog.entity)
                print(f'{dialog.title:<42}\t{dialog.id}')

asyncio.run(main())

Will output something like

channel_1           <channel_id>
