A simple to use library to create Telegram Bots in Java

Contributions

Feel free to fork this project, work on it and then make a pull request against DEV branch. Most of the times I will accept them if they add something valuable to the code.

Please, DO NOT PUSH ANY TOKEN OR API KEY, I will never accept a pull request with that content.

Webhooks vs GetUpdates

Both ways are supported, but I recommend long polling method.

Usage

Just import add the library to your project with one of these options:

1. Using Maven Central Repository:

    <dependency>
        <groupId>org.telegram</groupId>
        <artifactId>telegrambots</artifactId>
        <version>2.4.0</version>
    </dependency>

2. Using Jitpack from here
3. Download the jar(including all dependencies) from here

In order to use Long Polling mode, just create your own bot extending org.telegram.telegrambots.bots.TelegramLongPollingBot.

If you like to use Webhook, extend org.telegram.telegrambots.bots.TelegramWebhookBot

Once done, you just need to create a org.telegram.telegrambots.TelegramBotsApiand register your bots:

    // Example taken from https://github.com/rubenlagus/TelegramBotsExample
    public class Main {
        public static void main(String[] args) {
    
            TelegramBotsApi telegramBotsApi = new TelegramBotsApi();
            try {
                telegramBotsApi.registerBot(new ChannelHandlers());
                telegramBotsApi.registerBot(new DirectionsHandlers());
                telegramBotsApi.registerBot(new RaeHandlers());
                telegramBotsApi.registerBot(new WeatherHandlers());
                telegramBotsApi.registerBot(new TransifexHandlers());
                telegramBotsApi.registerBot(new FilesHandlers());
            } catch (TelegramApiException e) {
                e.printStackTrace();
            }
        }
    }
