How to get the Group or Channel id

1. Add the Telegram BOT to the group.

2. Message your bot in the group. E.g. if your bot is called ExampleBot, send a message from your personal account @ExampleBot /start to the group. Prior to this your bot does not have access to the messages in the chat.

3. Get the list of updates for your BOT:

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

Ex:

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

4. Look for the “chat” object:

{
    "update_id": 8393,
    "message": {
        "message_id": 3,
        "from": {
            "id": 7474,
            "first_name": "AAA"
        },
        "chat": {
            "id": <group_ID>,
            "title": "<Group name>"
        },
        "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.

5. Use the “id” of the “chat” object to send your messages (always negative?).
