Example

First you need to create a Telegram Bot

Open Telegram and search for @BotFather. It is the manager of all Telegram's bot. The bot creation happens entirely on the chat by using commands.

• Request a new bot: /newbot
  • @BotFather will ask you for a name to give: give-a-name-to-the-bot
• Finally request for a token: /token
  • @BotFather will reply you with a token. Copy it.
• Just if you want, you can sent the bot as an entity that can join Telegram groups: /setjoingroups
  • @BotFather will ask you to enable or disable the bot to join groups: enable | disable

Now you have activated your bot. Let's try to send a message:

let botToken = "the token you got from @BotFather";
let telegram: Telegram = new Telegram(botToken);
let userChatId: 12345678

/*
 * Generally, you need to know the Telegram ID of the user you want to involve in the action.
 */
let messagePayload: ISendMessagePayload = {
  chat_id: userChatId,
  text: "testing a text message"
}

telegram.messages.sendMessage(messagePayload).then((response) => {
  console.log(response);
}).catch((error) => {
  console.error(JSON.stringify(error));
});
