How can I retrieve all members of a Telegram group using Python-telegram-bot?

I’m working on a project with Python-telegram-bot and I need to fetch a list of everyone in a group where my bot is added. Is this even possible? I’ve looked through the docs but can’t find a clear answer. If it is doable, what’s the best way to go about it? I’m pretty new to Telegram bots, so any help or pointers would be awesome. Thanks!

hey there! unfortunately getting all members at once isnt really possible. even as an admin, telegram restricts that for privacy reasons. ur best bet is probably to track new members as they join and build ur list over time. just make sure to follow telegrams rules about data collection n stuff. good luck with ur project!

Retrieving all members of a Telegram group using Python-telegram-bot isn’t straightforward due to Telegram’s privacy policies. The bot can only access information about users who have interacted with it or if it has admin privileges. Even then, there are limitations. If your bot is an admin, you can use methods like getChatMembers() to fetch some data, but it may not work for large groups. A more reliable method is to track members as they join or interact with the group over time, storing their details locally. Always ensure that any data collection complies with Telegram’s terms of service and respects user privacy.

As someone who’s worked extensively with Telegram bots, I can tell you that retrieving all members of a group is indeed tricky. Telegram’s API doesn’t provide a straightforward method for this, primarily to protect user privacy.

In my experience, the most effective approach is to implement a listener for new member joins and departures. This way, you can gradually build up your member list over time. It’s not instant, but it’s reliable.

One caveat: this method only works for new members joining after you’ve implemented the listener. For existing members, you might need to encourage interaction with your bot to capture their data.

Remember to clearly communicate to users what data you’re collecting and why. Transparency is key when dealing with user information in any platform.
