      title Attention!
      For the correct notifications sending, you must select the HTTPS protocol.

9. In the IP address parameter, enter the IP address of the Telegram server—api.telegram.org.
10. In the Port parameter, enter the port of the Telegram server—443. 
11. In the Path parameter, enter the path of the query. The path of the query must look like this: /bot<BOTToken>/sendMessage?chat_id=<СhatID><ChatID>&&text=<Text>, where <BOTToken> is an ID of the bot in Telegram;

    Info
    title Note
    The ID is provided when you create the bot

    <СhatID> <ChatID> is the ID of the chat;
    

    Info
    title Note
    To learn the ID of the chat, add the @RawDataBot bot to the chat. After adding, the bot will send a message to the chat that will contain the result of the execution of the getUpdates function. Find ChatId in the message. Then remove the @RawDataBot bot from the chat.

    <Text> is a notification text. You can enter the set of US-ASCII characters (Latin characters and digits) in the notification text. For the notification text to display correctly with other characters and punctuation marks, you need to encode them. The encoding is described in the RFC 3986 standard and called URL-encoding, URLencoded, or percent-encoding. For example, a space character is encoded as %20.
