You can use the Telegram.mqh
It was written some time ago so most of it works but not all so for some functionality it will need some slight modifications.
Hi
I have the same problem. could you solve it?
PrintError(_LastError,InpLanguage);
What is the InpLanguage? Is there a function called PrintError() on mql4 and/or mql5?
Best.

Hi to all.
I'm trying to make an Expert. In this expert, I'm trying to send a picture to telegram bots.
- But I don't know why it sometimes works and sometimes doesn't works. In other words, sometimes send me the correct pic and sometimes I just see "sending a photo" in Telegram Bot. And I didn't receive anything.
- Surprisingly all pic that iI requested from Bot has saved correctly in "Files" folder
- I used Telegram.mqh and Comment.mqh libs in this Expert.
- I have tried expert with different servers, but the problem still remains.
Where is the problem
int SendScreenShot(const long _chat_id,
const string _symbol,

if(chart_id==0)
return(ERR_CHART_NOT_FOUND);
