I’m looking for a Telegram bot solution that can help me keep track of user activity across different groups. Specifically, I need something that can monitor which groups a person has been a member of over time and maintain a complete history of their group participation. This would include both current active memberships and previous groups they might have left. I’ve been searching around but haven’t found anything reliable yet. Does anyone know if such a bot exists or has experience building something similar? Any recommendations would be really helpful since I need to implement this for a project I’m working on.
totally get what ur saying! but for just simple tracking, maybe just stick to one group with a custom bot. tracking across groups can get tricky & privacy issues are a big deal. just a thought!
Been working on this lately and hit some gotchas that’ll save you headaches. Main problem is Telegram’s privacy setup limits cross-group tracking unless you own all the groups. Even then, you’re basically building surveillance tech - worth thinking about the ethics depending what you’re doing.
Technically, I built a centralized logging bot and made it admin in each target group. It grabs member_status updates and logs group_id, user_id, timestamp, and action type. Pain point is users with locked-down privacy - you’ll only get partial data or user IDs without usernames.
Something everyone’s missing: data retention laws. If you’re storing user membership history, GDPR and similar regs might apply depending where you operate. Get your data policies sorted before you start collecting anything.
Building this monitoring system isn’t straightforward because of Telegram’s API limits. The Bot API won’t give you a user’s full group list - bots only see what happens in groups they’re actually in. You need the bot installed in every group you want to track, and it only catches join/leave events when it’s running. For full tracking, set up webhook handlers to grab membership changes as they happen and dump everything into a database with timestamps. I’ve built similar stuff and PostgreSQL works great for tracking user histories across groups. The biggest pain point? Making sure your bot has admin permissions in all target groups so it can actually receive the member updates.
Been there with similar tracking needs. The real challenge isn’t building a bot - it’s handling data flow and storage without breaking things.
Most people code everything from scratch and hit rate limits plus storage nightmares. Managing user history across multiple groups gets messy fast with tons of edge cases.
I’ve found automation flows work way better. They handle bot logic, database updates, and data processing in one system. You can connect Telegram’s bot API to automatically log membership changes, store historical data, and trigger alerts when users join or leave groups.
You get proper error handling, automatic retries, and easy scaling without server headaches. I use this for community management - handles thousands of membership events daily.
