I am using the telepot python library, I know that you can send a message when you have someone\'s UserID(Which is a number). I wanna know if it is possible to send a messag
It's totally not safe to use other telegram versions available on internet, but I've seen that Telegram Plus has a ability to show you the chat_id of the user in their profile, even tho you don't have their contact.
Another way to extract chat_id of that particular user is that you have the phone number of that account, save it as your contact, then share it to this bot. It's easy to code it yourself but you can forward something from that user to this bot too, if you want to recieve the chat_id.
urmurmur has also mentioned another way. I haven't checked it yet but seems to be interesting.
