Hello,

After doing some work with the extension myself it looks like I was getting that error when I wasn't including the "-" in the chat ID, I'm not sure if your chat ID had this in front of the numbers but this cleared up the error for me and the chat message went through 

Let me know if this solves the issue for you!!

Unfortunately it is still error, but it succeed if i use this direct url:

https://api.telegram.org/bot{tokenbot}/sendMessage?chat_id={chatid}&text={msg}

I am still a newbie for bots. how to achieve the same with whatsapp?

regards and thanks
