Build AI Chatbots on Telegram, WhatsApp & Discord with Google ADK in Minutes 🚀

#ai #adk #agents #discord

Stop building custom chat UIs for every AI agent. Connect your Google ADK agents directly to Telegram, WhatsApp, and Discord with just a few lines of code.

If you've been experimenting with Google's Agent Development Kit (ADK), you've probably realized something:

Building an intelligent AI agent is easy.
Deploying it where users actually are?
That's the hard part.

Most tutorials end after the agent is running locally. But in the real world, your users don't want to visit another website just to talk to your AI.

They already use:

Telegram
WhatsApp
Discord
Slack

So why not deploy your ADK agent there?

That's exactly why I built ADK Connectors.

What is Google ADK?

Google's Agent Development Kit (ADK) is an open-source framework for building production-ready AI agents.

With ADK you can:

Build autonomous AI agents
Add tools and memory
Connect to LLMs
Create multi-agent workflows
Deploy production AI applications

The Problem

Imagine you've built an amazing customer support agent using ADK.

Now what?

You'll need to build:

A frontend
Authentication
Chat UI
Messaging integration
Webhook server
Platform-specific APIs

That could easily become hundreds (or thousands) of lines of code before anyone can even chat with your AI.

Meet ADK Connectors

ADK Connectors lets you connect your ADK agents directly to messaging platforms.

Instead of building an entire frontend, you simply attach a connector.

Current integrations include:

✅ Telegram
✅ WhatsApp
✅ Discord
🚧 Slack (Coming Soon)

The library handles the platform integration so you can focus on building better AI agents.

Installation
Python
pip install adk-connector

PyPI

JavaScript / Node.js
npm install adk-connector-js

NPM

One agent.

Multiple platforms.

Minimal setup.

Example

Suppose you've already built an ADK agent.

Instead of creating a custom frontend, simply attach a connector.

Example (illustrative)

from adk_connector import TelegramConnector

TelegramConnector(agent).run()

That's it.

Your AI agent is now available on Telegram.

The same idea applies to WhatsApp and Discord connectors.

(See the official documentation for complete examples.)

Why I Built This

When I started working with Google ADK, I noticed there wasn't a simple way to expose an agent across multiple messaging platforms.
Every platform required writing boilerplate code, configuring APIs, and handling messages separately.
I wanted a reusable toolkit that lets developers focus on building intelligent agents—not wiring up integrations.
That idea became ADK Connectors.
I'm excited that the project is now featured in the official Google ADK documentation, making it easier for other developers to get started.
