How to send a message to a user in Telegram from a bot?

Question

Python

1) I created a bot
2) I initiated a conversation with him
3) I make a request (token and chat id inserted my own)

https://api.telegram.org/bot<token>/sendMessage?chat_id=<chatId>&text=Hello

As a result, I get the response {"ok":false,"error_code":403,"description":"Forbidden: bot can't initiate conversation with a user"}
Tell me what's wrong.

Answer 1

From the error, we see that the bot cannot create a conversation. Are you sure you create it through an account, and not through a bot? Check the variables carefully: user id, etc.
It's hard to say what the error is without seeing the code ... Throw it here - we will solve the problem)
What library did you use? Up-to-date? They had an update there not so long ago, MB of which they changed - in the order of a complete nonsense idea.

Answer 2

Maybe you are specifying the wrong chat_id? Or a token from another bot?
And so in the description everything is described.

Answer 3

The API reported that the robot could not initiate a conversation. You must first do this from your Telegram account.
1. Type in the search @username_bot_who_specified_when_created
2. It will appear in the contact list
3. Click on it
4. Click "Start" The
conversation has been created now The robot will normally send messages
