[telegram] Telegram Bot - how to get a group chat id?

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/

You can get Chat ID in this way.

On private chat with your bot, send a random message. You will search this message later.

Get Your API-token from bot_father : XXXXXXXXX:YYYYYYY-YYYYYYYYYYYYYYYYY_YY

Then, on your browser make a request with that url :

https://api.telegram.org/botXXXXXXXXX:YYYYYYY-YYYYYYYYYYYYYYYYY_YY/getUpdates

The request returns a json response, in json text search your random message and get chat id in that object.

Here is the sequence that worked for me after struggling for several hours:

Assume the bot name is my_bot.

1- Add the bot to the group.
Go to the group, click on group name, click on Add members, in the searchbox search for your bot like this: @my_bot, select your bot and click add.

2- Send a dummy message to the bot.
You can use this example: /my_id @my_bot
(I tried a few messages, not all the messages work. The example above works fine. Maybe the message should start with /)

3- Go to following url: https://api.telegram.org/botXXX:YYYY/getUpdates
replace XXX:YYYY with your bot token

4- Look for "chat":{"id":-zzzzzzzzzz,
-zzzzzzzzzz is your chat id (with the negative sign).

5- Testing: You can test sending a message to the group with a curl:

curl -X POST "https://api.telegram.org/botXXX:YYYY/sendMessage" -d "chat_id=-zzzzzzzzzz&text=my sample text"

If you miss step 2, there would be no update for the group you are looking for. Also if there are multiple groups, you can look for the group name in the response ("title":"group_name").

Hope this helps.

As of March 2020, simply:

• Invite @RawDataBot to your group.

Upon joining it will output a JSON file where your chat id will be located at message.chat.id.

"message": {
    "chat": {
        "id": -210987654,
        "title": ...,
        "type": "group",
        ...
    }
    ...
}

Be sure to kick @RawDataBot from your group afterwards.

Using python and telethon it's very easy to get chat id. This solution is best for those who work with telegram API.

If you don't have telethon, run this:

pip install telethon

If you don't have a registered app with telegram, register one: The link is this: https://my.telegram.org/

Then run the following code:

from telethon import InteractiveTelegramClient
from telethon.utils.tl_utils import get_display_name

client = InteractiveTelegramClient('session_id', 'YOUR_PHONE_NUMBER', api_id=1234YOURAPI_ID, api_hash='YOUR_API_HASH')

dialog_count = 10
dialogs, entities = client.get_dialogs(dialog_count)
for i, entity in enumerate(entities):
                    i += 1  # 1-based index
                    print('{}. {}. id: {}'.format(i, get_display_name(entity), entity.id))

You may want to send a message to your group so the group show up in top of the list.

create a bot, or if already created set as follows:

has access to messages

apparently, regardless of how old/new the Telegram group is:

1. add a bot to the group

2. remove bot from the group

3. add bot again to the group

4. create a script file and run getUpdates method example:

    var vApiTokenTelegram = "1234567890:???>yg5GeL5PuItAOEhvdcPPELAOCCy3jBo"; // @?????Bot API token
    var vUrlTelegram = "https://api.telegram.org/bot" + vApiTokenTelegram;

    function getUpdates() {
        var response = UrlFetchApp.fetch(vUrlTelegram + "/getUpdates");
        console.log(response.getContentText());
    }

5. function shall log to the console the following:

[20-04-21 00:46:11:130 PDT] {"ok":true,"result":[{"update_id":81329501,
"message":{"message_id":975,"from":{"id":962548471,"is_bot":false,"first_name":"Trajano","last_name":"Roberto","username":"TrajanoRoberto","language_code":"en"},"chat":{"id":-1001202656383,"title":"R\u00e1dioRN - A voz da na\u00e7\u00e3o!","type":"supergroup"},"date":1587454914,"left_chat_participant":{"id":1215098445,"is_bot":true,"first_name":"MediaFlamengoRawBot","username":"MediaFlamengoRawBot"},"left_chat_member":{"id":1215098445,"is_bot":true,"first_name":"MediaFlamengoRawBot","username":"MediaFlamengoRawBot"}}},{"update_id":81329502,

6. Telegram group chat_id can be extracted from above message "chat":{"id":-1001202656383,"title"

After mid-2018:
1:) Invite @getidsbot or @RawDataBot to your group and get your group id from the chat id field.

Message
 + message_id: 338
 + from
 ?  + id: *****
 ?  + is_bot: false
 ?  + first_name: ???
 ?  + username: ******
 ?  + language_code: en
 + chat
 ?  + id: -1001118554477    // This is Your Group id
 ?  + title: Test Group
 ?  + type: supergroup
 + date: 1544948900
 + text: A

2:) use an unofficial Messenger like Plus Messenger and see your group id in group/channel info.

Before mid-2018: (don't Use)
1: Goto (https://web.telegram.org)
2: Goto your Gorup and Find your link of Gorup(https://web.telegram.org/#/im?p=g154513121)
3: Copy That number after g and put a (-) Before That -154513121
4: Send Your Message to Gorup bot.sendMessage(-154513121, "Hi")
I Tested Now and Work like a Charm

My second Solution for the error {"ok":true,"result":[]}

1. Go in your Telegram Group
2. Add new User (Invite)
3. Search for "getidsbot" => @getidsbot
4. Message: /start@getidsbot
5. Now you see the ID. looks like 1068773197, which is -1001068773197 for bots (with -100 prefix)!!!
6. Kick the bot from the Group.
7. Now go to the Webbrowser an send this line (Test Message):

https://api.telegram.org/botAPITOKENNUMBER:APITOKENKEYHERE/sendmessage?chat_id=-100GROUPNUMBER&text=test

Edit the API Token and the Group-ID!

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.

If you are implementing your bot, keep stored a group name -> id table, and ask it with a command. Then you can also send per name.

I tested now 4h but it dont work 2021 with the group-chat-id. All the time the error {"ok":true,"result":[]}

But now i found a Solution:

1:) install the "Plus Messenger" (https://play.google.com/store/apps/details?id=org.telegram.plus)

2:) go in the Group => Tap now on the "Group-Name" in the Head => Double Tap now on the Headline from the Group. A Info is comming: ID123456789 is copy in the clipboard

3:) go in the Group an paste the clipboard text. It´s you Groud-ID

4:) looks like 1068773197, which is -1001068773197 for bots (with -100 prefix)!!!

btw, you see the user-id too, on your profil.

5:) Now go to the Webbrowser an send this line (Test Message):

https://api.telegram.org/botAPITOKENNUMBER:APITOKENKEYHERE/sendmessage?chat_id=-100GROUPNUMBER&text=test

Edit the API Token and the Group-ID!

You can retrieve the group ID the same way. It appears in the message body as message.chat.id and it's usually a negative number, where normal chats are positive.

Group IDs and Chat IDs can only be retrieved from a received message, there are no calls available to retrieve active groups etc. You have to remember the group ID when you receive the message and store it in cache or something similar.

IMHO the best way to do this is using TeleThon, but given that the answer by apadana is outdated beyond repair, I will write the working solution here:

import os
import sys
from telethon import TelegramClient
from telethon.utils import get_display_name

import nest_asyncio
nest_asyncio.apply()

session_name = "<session_name>"
api_id = <api_id>
api_hash = "<api_hash>"
dialog_count = 10 # you may change this

if f"{session_name}.session" in os.listdir():
    os.remove(f"{session_name}.session")

client = TelegramClient(session_name, api_id, api_hash)

async def main():
    dialogs = await client.get_dialogs(dialog_count)
    for dialog in dialogs:
        print(get_display_name(dialog.entity), dialog.entity.id)

async with client:
    client.loop.run_until_complete(main())

this snippet will give you the first 10 chats in your Telegram.

Assumptions:

• you have telethon and nest_asyncio installed
• you have api_id and api_hash from my.telegram.org
