How to get a Telegram Channel Id without sending a message to it

Question

Is there any way to find a telegram channel id without sending a message to it ?

Right now I go this way and find the channel id by calling this URL in my code and get the JSON as result: https://api.telegram.org/bot???????/sendMessage?chat_id=@?????&text=123

However, this cause sending the message "123" to the channel which is not good.

Answer 1

Check this link for help.
It is using web telegram url param info.

Adding details from the referred link:

1. log in web telegram
2. Click on the target channel then you will find the url displayed on your browser.

If it's a public channel, the ID is @name of the channel.

If it's a private channel then the url must be similar to:
https://web.telegram.org/#/im?p=c1018013852_555990343349619165
For this case, the channel ID would be 1018013852.
It's important to know that channel's IDs are always negative and 13 characters long!
So add -100 to it, making the correct ID -1001018013852.

You Can use Web Telegram to see each channel id in link of that page in your explorer
or

Just Simply Forward a message from your channel to This Bot: (https://telegram.me/getidsbot)

Good Answer, But unfortunately the Bot not answering. I am using (telegram.me/telebot_robot)[@telebot_robot] that works perfect – Halsy

GetIDs Bot works fine at the moment. If not, one can deploy a new copy of the bot: github.com/wjclub/telegram-bot-getids . As a backup, here is my bot on AWS Lambda (which means that it's free to maintain): t.me/itpp_myid_bot – Skipbomb

Answer 3

Yes, just forward a message of the channel to your bot and get the message.forward_from_chat.id.

Answer 4

1. Get your channel link

2. install python library telethon

3. get your api_id and api_hash here.

4. write the following code and run:

    from telethon import TelegramClient
    api_id=
    api_hash=
    channel_link = 'your_channel_link'
    client = TelegramClient(session_name, api_id, api_hash,
                            update_workers=4, spawn_read_thread=False)
    client.start()
    entity = client.get_input_entity(**channel_link**)
    print(entity.channel_id)
   

By the way, if you use it for telegram bot, just add -100 before the printed id, this should be work!

Answer 5

Put your bot into your channel and go to https://api.telegram.org/bot/getUpdates.

If someone send message to that channel, you will get the channel ID there.

Fixing @scruel's answer:

In [1]: api_id = ...

In [5]: client = TelegramClient('test', api_id, api_hash)                                                                                                 

In [6]: client.start()

Here's a CLI util to do it:

#!env/bin/python

import sys
import asyncio

from telethon import TelegramClient

import config

async def channel_id_from_link(client, channel_link):
    return "-100" + str((await client.get_entity(channel_link)).id)

async def main(channel_link):
    async with TelegramClient(
        "test", config.api_id, config.api_hash
    ) as client:
        channel_id = await channel_id_from_link(client, channel_link)

    return channel_id

if __name__ == "__main__":
    channel_link = sys.argv[1]
    channel_id = asyncio.run(main(channel_link))
    print(channel_id)
