Notification When Public IP Address Router Changes - MikroTik Script RouterOS

Notification when the external IP address of the MikroTik router changes. Send a message to email or Telegram.
The script creates a global variable CurrentIP to store the current external IP address of the MikroTik router.
The script uses the ipify.org service API to get an external IP address.

:global CurrentIP;
:local NewIP ([/tool fetch url=http://api.ipify.org/ as-value output=user] -> "data")

:if ($NewIP != $CurrentIP) do={
    # Variables
    :local Time [/system clock get time];
    :local Date [/system clock get date];
    :local DeviceName [/system identity get name];
    :local Text "New IP: $NewIP, Previous IP: $CurrentIP";
    :set CurrentIP $NewIP;

    # START Send Telegram Module
    :local MessageText "\F0\9F\9F\A2 $DeviceName: External IP address has changed. $Text";
    :local SendTelegramMessage [:parse [/system script  get MyTGBotSendMessage source]]; 
    $SendTelegramMessage MessageText=$MessageText;
    #END Send Telegram Module

    # START Send Email Module
