How to retrieve private chat id or group chat id

To retrieve group chat id, makes sure you have invited your bot to your group, for example we are using this bot

username  : my_awesome_openwrt_bot
bot token : 61102xxxxx:AAHnmbXKLisxejOBBVVxxxxxxxxxxxx

Send message to group and mention your bot, ex: /my_id @my_awesome_openwrt_bot
Get update your bot by visiting url like this

{
    "ok": true,
    "result": [
        {
            ...
            "message": {
                "from": {
                    ...
                    "username": "lutfailham"
                },
                "chat": {
                    "id": -9271xxxxx, // This is group chat id
                    "type": "group"
                    ...
                },
                "text": "/my_id @my_awesome_openwrt_bot",
                ...
            }
        }
    ]
}

as we can see, retrieved group chat id is -9271xxxxx
