Telegram Bot - how to get a group chat id?

Question

I've been using telegram_bot, and trying to get groupChat id to send notifications to group chat, but don't know which methods I have to use for it.

For getting chat id I use to message.chat.id when the bot participated in the chat but which I have to use for getting group chat id can't find/

Answer 1

In order to get the group chat id, do as follows:

1. Add the Telegram BOT to the group.

2. Get the list of updates for your BOT:

   https://api.telegram.org/bot<YourBOTToken>/getUpdates
   

   Ex:

   https://api.telegram.org/bot123456789:jbd78sadvbdy63d37gda37bd8/getUpdates
   

3. Look for the "chat" object:

{"update_id":8393,"message":{"message_id":3,"from":{"id":7474,"first_name":"AAA"},"chat":{"id":,"title":""},"date":25497,"new_chat_participant":{"id":71,"first_name":"NAME","username":"YOUR_BOT_NAME"}}}

This is a sample of the response when you add your BOT into a group.

4. Use the "id" of the "chat" object to send your messages.
