Send Audio Files to Telegram Groups in Java - Complete Guide

Automate Telegram Group Audio Sharing with Java

Need to deliver audio content, voice announcements, or sound notifications to Telegram groups from your Java applications? This guide walks you through sending audio files (MP3 format) to Telegram groups using Java and the WhatsMate Telegram Gateway REST API. Perfect for Java developers, community managers, and automation enthusiasts who want to integrate group audio delivery into their Java-based workflows.

📋 Prerequisites

Before you begin, ensure you have:

1. A WhatsMate Telegram Gateway account - Required for API access
2. Group registration - The Telegram group must be registered with the Gateway first
3. Java development environment - JDK installed and configured
4. Basic Java knowledge - Familiarity with Java programming
5. Audio file ready - Have the MP3 file you want to send available locally
6. Required libraries - Gson and Commons Codec (details in code comments)

⚠️ Important: Telegram groups must be registered with the WhatsMate Telegram Gateway before they can receive messages. Unregistered groups will not receive any messages from the Gateway. Registration instructions are available on the official WhatsMate site.

📝 Step-by-Step Implementation

Follow these steps to send your first audio file to a Telegram group from a Java application:

1. Copy the Java Code Template

Start by copying the following source code into your Java file:

2. Configure a few Parameters

Customize these key parameters in the Java code:

• Lines 51-53: Replace YOUR_INSTANCE_ID_HERE, YOUR_CLIENT_ID_HERE, and YOUR_CLIENT_SECRET_HERE with your Telegram gateway credentials
• Line 61: Replace Muscle Men Club with your target Telegram group name
• Line 62: Replace 19159876123 with the phone number of the group admin (including country code)
• Line 64: Replace ../assets/ocean-waves.mp3 with the path to your MP3 audio file
• Line 66: Replace anyname.mp3 with the desired filename for the audio
• Line 67: Replace Enjoy the nature with an optional caption for your audio

3. Set Up Dependencies

Add the required libraries to your project:

If using Maven, add these dependencies to your pom.xml:

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.0</version>
</dependency>
<dependency>
    <groupId>commons-codec</groupId>
    <artifactId>commons-codec</artifactId>
    <version>1.10</version>
</dependency>

4. Compile and Run

Compile and execute your Java program:

If using Maven (after adding dependencies to pom.xml):

mvn compile
mvn exec:java -Dexec.mainClass="TelegramGroupMp3Sender"

If not using Maven:

# Compile with required JAR files
javac -cp "jars/gson-2.8.0.jar:jars/commons-codec-1.10.jar" TelegramGroupMp3Sender.java

# Run the compiled program
java -cp ".:jars/gson-2.8.0.jar:jars/commons-codec-1.10.jar" TelegramGroupMp3Sender

🔧 Common Use Cases

This automation approach is ideal for:

• Group announcements - Send audio updates or announcements to Telegram groups from Java applications
• Team notifications - Deliver voice notifications or alerts to team collaboration groups
• Audio content distribution - Share podcasts, music, or audio recordings with group members via Java
• Enterprise integrations - Incorporate Telegram group audio delivery into existing Java enterprise systems
• Automated voice messages - Send pre-recorded voice announcements to multiple groups from Java services
