Telegram Bot "chat not found"
Question:
I have the following code in Python to send a message to myself from a bot.
import requests
token = '123456789:ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHI'
method = 'sendMessage'
myuserid = 1949275XX
response = requests.post(
url='https://api.telegram.org/bot{0}/{1}'.format(token, method),
data={'chat_id': myuserid, 'text': 'hello friend'}
).json()
print(response)
but this returns {'description': 'Bad Request: chat not found', 'error_code': 400, 'ok': False}
What am I doing wrong? I got myuserid by sending /getid to @myidbot and I got my token from @BotFather
Answers:
As @maak pointed out, you need to first send a message to the bot before the bot can send messages to you.
There is a way to send notifications messages to telegram. It’s a bit tricky but the tutorial is great!

I just sended a message of my apache state to a privat channel.
Works also on public channel but it’s not what i wantet. As you call a script (bash) you can prepare the parameters in any script language.
Hope that helps.
If your trying to send messages to a group, you must add a ‘-‘ in front of your chat ID.
For example:
TELEGRAM_REG_CHAT_ID="1949275XX"
should be
TELEGRAM_REG_CHAT_ID="-1949275XX"
I was using prefix @ before the value of chat_id as suggested everywhere. I removed it and it started working.
Note: if your chat id is 12345678 then you need to prefix it with -100 such that it is -10012345678.
Example Postman call:
/sendMessage?chat_id=-10012345678&text=Let's get together
For me it worked only with @ prefix before channel id
If you use a username, it does not require any prefix. That means the following are incorrect:
https://t.me/vahid_esmaily_ie
t.me/vahid_esmaily_ie
And this is the correct case:
vahid_esmaily_ie
If you want to use a bot message to the channel, you can refer step here
Steps:
- Create a Telegram public channel
- Create a Telegram BOT (for example
x_bot) via BotFather
- Set the
x_bot as an administrator in your channel
the chat_id is @x_bot, it’s a part of https://t.me/x_bot that does not add your channel name.
I had some trouble with this after upgrading to a supergroup. The chat_id was updated and it was a bit harder to find this new id.
In the end I solved this with this by following this comment: https://stackoverflow.com/a/56078309/14213187
Telegram bots can’t send messages to user, if that user hasn’t started conversation with bot yet, or bot is not present in chat (if it’s a group chat). This issue is not related to the library, this is simply Telegram restriction, so that bots can’t spam users without their permission.
