Question

I have channel and I want to send automatic messages to this channel using C# and telegram API.

What should I do?

Answer 1

First create a bot and add that as an administrator to your channel

Adding Bot as administrator to channel

Creating Bot

then use the following code to send message to your group

WebRequest req = WebRequest.Create("https://api.telegram.org/bot" + yourToken + "/sendMessage?chat_id=" + channel_id + "&text=" + message);
req.UseDefaultCredentials = true;

var result = req.GetResponse();
req.Abort();

yourToken is your bot's token, channel_id is your channel's ID and message is a string that you want to send to your channel
