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
-
Talk to BotFather
Open Telegram and search for@BotFather. This is Telegram’s official bot manager. -
Create a new bot
Send the command:/newbotYou’ll be prompted to:
- Name your bot
- Choose a username (must end in
bot)
Example username:
n1netails_alertbot -
Save your bot token
BotFather will generate a token such as:123456789:ABCdefGhIJKlmNoPQRstuVWXyz⚠️ Keep this private — anyone with it controls your bot.
-
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. -
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.
