TelegramSendPhoto

A wrapper for the Telegram sendMessage function to send a photo (blocking execution).

This function invokes an asynchronous request to the Telegram API. To ensure successful sending of the message this function waits for the callback. If you need to return back to the caller function quickly use TelegramSendPhotoAsync instead.

Parameter

string apiKey

The Telegram bot API key

string chatId

The Telegram chat ID that will receive the message

string filePath

The path to the file that shall be sent

string caption

The caption for the photo

Returns

A string indicating if the request was successfully invoked. 0 means there was no failure.

Code Example

   Print(TelegramSendPhoto(apikey, chatid, "F:\\testpic.jpg", "test photo")); // Will print "0" on success

Remarks

  • Use this function in conjunction with MQL native functions like chartscreenshot.
  • If your pictures exceed a maximum resolution/size Telegram will shrink the size of your pictures. Use TelegramSendDocument[Async] instead to send full sized images.
