Set up a Telegram Messenger bot for NT8 alerts

[Rober182]

To see if you can help me, Is there any way to set up a Telegram Messenger bot and receive messages and notifications from NT8? Is it possible to configure it from "share services" in the same way that the sending of alerts by email is configured?

Thanks for your time.

Hello Rober182,

You will need to setup an SMTP share service first. Then you will be able to call SendMail() from a NinjaScript or from the Alerts window.

Below is a link to a forum thread that discusses this.

Thanks you, ChelseaB

somebody was working on it, i think on futures io but eventually gave up because telegram API or the library for it for C# made things a bit complicated.

You have much simpler solutions for sending text to a Telegram bot. For example, you can just call this function:

public void SendMessage(string msg, string bottoken, string chatid)
{

bool sender = false;
string url = "https://api.telegram.org/bot"+bottoken+"/sendMessage?chat_id="+chatid+"&parse_mode=html&tex t=";
url = url + msg;

using (var wb = new WebClient()){

try
{
var response = wb.DownloadString(url);
sender = true;
}
catch (Exception ex)
{
return;
}

}

}

Pls do not forget adding:
using System.Net;

If you want to also send chart images, that would require using Telegram.Bot dll

Thanks for this. I tested it out and worked, but found you have an extra space in the string URL which was causing it to fail.

string url = "https://api.telegram.org/bot"+bottoken+"/sendMessage?chat_id="+chatid+"&parse_mode=html&tex t=";

[edit] that's odd, the space gets added by the forum?! anyway, you just need to remove the space in the text at the end of the string. Hope that helps.

If one wants to broadcast to a bot channel, how does one find the relevant chat_id of that bot channel? [The token is easy as it's provided at bot creation.]

Thanks.

That was very helpful. Thanks!

[jeronymite]

cls71 Thanks. Helpful indeed. The Spanish was a bit of a challenge, but the Vivaldi browser has built-in translation that worked very well for this.

Thanks.

Maybe someone finds this useful. I had a problem with sending screenshot to Telegram, a common thread error: The calling thread cannot access this object because a different thread owns it.
So I fixed it:

private void SendScreenshot()
{
SendScreenshotAsync();
}
private async Task SendScreenshotAsync()
{
RenderTargetBitmap screen = null;
await Dispatcher.BeginInvoke(new Action(() => { Chart = Window.GetWindow(ChartControl) as Chart; screen = Chart.GetScreenshot(ShareScreenshotType.Chart); }));
// if (Chart == null) Print("Chart null");
// if (screen == null) Print("screen null");
if (screen == null) return;

BitmapFrame output = BitmapFrame.Create(screen);
byte[] bytes;
using (MemoryStream ms = new MemoryStream())
{

PngBitmapEncoder png = new PngBitmapEncoder();
png.Frames.Add(output);
png.Save(ms);
bytes = ms.ToArray();
}

try
{
//https://github.com/TelegramBots/Telegram.Bot/issues/867
//https://stackoverflow.com/questions/50768640/change-dns-in-windows-using-c-sharp
//set to 8.8.8.8
// System.Net.ServicePointManager.SecurityProtocol |= System.Net.SecurityProtocolType.Tls11 | System.Net.SecurityProtocolType.Tls12; // in .net 4.6 it's default, in 4.5 this code you need to use
MemoryStream ms = new MemoryStream(bytes);
await Bot.SendPhotoAsync(ChatID, ms);
ms.Dispose();
}
catch (Exception e)
{
Log("SendScreenshotAsync exception: " + e.ToString(), LogLevel.Error);
}
}
