Minimal "hello world" telegram bot

Here, in four steps, the magician will show how to assemble the bot annunciator for a telegram without pain and reading the documentation.

1. Sign up for a telegram
2. Get the ID of the new bot (hereinafter <Bot_token> ): contact the @BotFather bot with a request to create a new bot (/ newbot command)
3. Get the ID of the conversation with the bot (hereinafter <chat_id> ):
   
   • Open a dialogue with your created bot and write an arbitrary message to it.
   • Open the link in the browser, replacing <Bot_token> with the received identifier from @BotFather https://api.telegram.org/bot<Bot_token>/getUpdates
   • In the received json-answer, find the value in the parameter result-> message-> chat-> id, this is <chat-id>
4. Open a browser and follow the link, replacing <Bot_token> and <chat_id> with your data
   https://api.telegram.org/bot<Bot_token>/sendMessage?chat_id=<chat_id>&text=%20

Thus, you will receive a message from the bot to all your devices with a telegram client.

You can use the last call in a bat-file or console or distribute to friends who do not have a telegram and write from a smart iron (but only to very good friends as <Bot_token> confidential information actually).
