I have a private channel on telegram in which I have added my bot. I am able to create unique links for each user to join the channel. Now I want to know userID of the user who have joined the channel. The reason for me to get userID is because the channel is subscription based and I would want to remove the user once their subscription ends and they don’t resubscribe.
