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

Answer 1

正如@maak 指出的那样，您需要先向机器人发送消息，然后机器人才能向您发送消息。

Answer 2

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"

Answer 3

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.

Answer 4

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

Answer 5

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

Answer 6

对我来说，它只在频道 id 之前使用@前缀

Answer 7

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

Answer 8

If you want to use a bot message to the channel, you can refer step here

Steps:

1. Create a Telegram public channel
2. Create a Telegram BOT (for example x_bot ) via BotFather
3. 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.

Answer 9

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.

you need to first send a message to the bot before the bot can send messages to you.
