I have not looked at this in detail, but I can't see what advantages this has over just sending a simple http request like this:

  https://api.telegram.com/botTOKEN/sendMessage?id=YOUR_ID&message="your servers are on fire"

because that's all you need as far as I know. Works via GET, POST, PUT, everything.

Only thing I could see is being able to switch it out for other services easier.
