A Java solution using the Teamspeak Query Interface and a Socket connection.

• Contains everything from the TeamSpeak Query Manual
• Keeps the connection to the server using a KeepAliveThread
• Event system using threads
• Advanced options for debugging and logging
• Synchronous and asynchronous API

Everything the API needs is in the Ts3ServerQuery Class and the Ts3SyncAPI Class.

public class Test {
    
    public static void main(String[] args) {
        Ts3ServerQuery query = new Ts3ServerQuery();
        try {
            query.connect("hostname", 10011, "Username", "Passwort", 1, "Ts³-Bot", 1);
        } catch (IOException | QueryLoginException e) {
            e.printStackTrace();
        }
    }
}

See How to start with the API.

See How to debug with the API or Advanced Debugging.
Or see Example Log.

See AdvancedAPI usage.

The Floodrate for the TsAPI is set to 0 ms per default (FloodRate.DEFAULT_TSAPI).
TeamSpeaks default Floodrate is set to 350 ms (FloodRate.DEFAULT).
(FloodRate.UNLIMITED) is set to 0 like the FloodRate.DEFAULT_TSAPI so it does not matter which one you choose and you do not have to set this one in the most chases.
Or set a custom value with FloodRate.custom(300).
