Can I Get A Phone Number By User Id Via Telegram Bot API?
Answer : No, unfortunately Telegram Bot API doesn't return phone number. You should either use Telegram API methods instead or ask it explicitly from the user. You cannot get "friends" of a user as well. You will definitely retrieve the following information: userid first_name content (whatever it is: text, photo, etc.) date (unixtime) chat_id If user configured it, you will also get last_name and username . It's possible with bots 2.0 check out bot api docs. https://core.telegram.org/bots/2-0-intro#locations-and-numbers https://core.telegram.org/bots/api#keyboardbutton
