How to get Telegram Bot Super Group ID?
With This Code:
bot.on('message', (msg) => {
console.log(msg);
});
I Can See my Private Channel ID in forward_from_chat: { id: -1001125265425, of the object, That is Okey.
But How Can I Get Super Group ID?
First of all, you should add a bot to that group.
Then if the group is public (has @username), just send message to the group and read reply from Telegram server, it will be of type Message, and Message->Chat->Id is group's ID.
If the group is private (doesn't have a @username), then you can mention a bot in your message and, again, read reply from Telegram server.
Or you can use some third-party bots, for example, @my_id_bot, which I made specifically for this.
