N1netails Telegram Client – Quick Start Guide

If you’ve ever wanted to send automated alerts, notifications, or rich‑media messages to Telegram from your Java application, you’ve probably discovered that working directly with the Telegram Bot API can get repetitive fast.

That’s where N1netails Telegram Client comes in – a lightweight, open‑source Java library designed to make sending Telegram messages simple, structured, and production‑ready.

In this guide you’ll learn:

  • ✅ How to create a Telegram bot
  • ✅ How to configure the N1netails client
  • ✅ How to send text, GIFs, images, videos, and media groups
  • ✅ How to add call‑to‑action (CTA) buttons

What is N1netails Telegram Client?

N1netails is an open‑source project focused on practical alerting and monitoring. The Telegram client module lets you easily send structured Telegram messages from Java applications, perfect for:

  • Alerting systems
  • Automation tools
  • Monitoring dashboards
  • DevOps workflows
  • App notifications

Instead of hand‑crafting API requests, you work with clean Java objects.

Step 1 – Set Up Telegram

Install Telegram

Download Telegram on your smartphone first:
👉

Telegram requires initial mobile setup before desktop use.

Create Your Telegram Bot

  1. Talk to BotFather
    Open Telegram and search for @BotFather. This is Telegram’s official bot manager.

  2. Create a new bot
    Send the command:

    /newbot

    You’ll be prompted to:

    • Name your bot
    • Choose a username (must end in bot)

    Example username: n1netails_alertbot

  3. Save your bot token
    BotFather will generate a token such as:

    123456789:ABCdefGhIJKlmNoPQRstuVWXyz

    ⚠️ Keep this private — anyone with it controls your bot.

  4. Add the bot to a chat
    Add your bot to a group chat or a direct chat and ensure it has permission to send messages.

  5. Get the chat ID

    • Option A – Use a helper bot: @getidsbot

    • Option B – Use the Telegram API:

      curl https://api.telegram.org/bot/getUpdates

    Look for "chat":{"id":...} in the response.

You now have:

  • ✔ Bot token
  • ✔ Chat ID

Step 2 – Install the Library

Maven


  com.n1netails
  n1netails-telegram-client
  0.3.0

Gradle

implementation 'com.n1netails:n1netails-telegram-client:0.3.0'

Step 3 – Configuration

Spring Boot Setup

@Configuration
public class TelegramConfig {

  @Bean
  public BotService botService() {
    return new BotService();
  }

  @Bean
  public TelegramClient telegramClient(BotService service) {
    return new TelegramClientImpl(service);
  }
}

Plain Java Setup

BotService service = new BotService();
TelegramClient client = new TelegramClientImpl(service);

Step 4 – Sending Messages

Simple Text Message

TelegramMessage msg = new TelegramMessage("Telegram works!", false);
client.sendMessage(chatId, botToken, msg);

GIF Message

TelegramMessage msg = new TelegramMessage(
    "Check this GIF!",
    "https://giphy-url.gif",
    false
);
client.sendMessage(chatId, botToken, msg);

CTA Button Message

Button button = new Button("Visit Site", "https://example.com");
InlineKeyboardMarkup markup = new InlineKeyboardMarkup(
    List.of(List.of(button))
);
TelegramMessage msg = new TelegramMessage("Click below!", false, markup);
client.sendMessage(chatId, botToken, msg);

Image Message

TelegramMessage msg = new TelegramMessage();
msg.setText("Photo alert!");
msg.setImages(List.of("https://image-url.png"));
client.sendMessage(chatId, botToken, msg);

Video Message

TelegramMessage msg = new TelegramMessage();
msg.setText("Video alert!");
msg.setVideos(List.of("https://video-url.mp4"));
client.sendMessage(chatId, botToken, msg);

Media Group (Images + Videos)

TelegramMessage msg = new TelegramMessage();
msg.setText("Media bundle!");
msg.setImages(List.of("image1.png", "image2.png"));
msg.setVideos(List.of("video.mp4"));
client.sendMessage(chatId, botToken, msg);

⚠️ Note: Telegram does not allow CTA buttons with media groups.


Important Notes

  • Media must be public URLs.
  • CTA buttons only work with single‑media messages.
  • Keep bot tokens secure.
