I recently worked on a project that let me explore some exciting areas like:
- Building Telegram bots
- Using WhatsApp APIs
- Playing with asynchronous programming
- Developing and consuming APIs
The result? 👉 WATele-Bridge – a simple, self-hosted bridge between Telegram and WhatsApp.
🔧 How It Works
The project has two main parts:
- Telegram Bot (Python, Telethon)
- Listens for new messages from a user-specified chat, group, or channel.
- Whenever a new message arrives, it triggers an event handler.
- That event makes an HTTP request to an API endpoint.
- WhatsApp API (Node.js, '@whiskeysockets/Baileys')
- Exposes a send-message endpoint.
- Receives the incoming request from the Telegram bot.
- Forwards the message directly to WhatsApp.
This essentially creates a Telegram → WhatsApp relay.
⚡ Why I Built This
I wanted to:
- Learn Telethon for Telegram bot development.
- Explore Baileys (a popular WhatsApp Web API library).
- Understand how to design async message handling.
- Practice building and integrating a small microservice API.
It’s a great project if you’re curious about combining different chat platforms or experimenting with real-time communication apps.
🚀 Try It Yourself
You can self-host the project with the instructions in the repo:
👉 github.com/Azizham66/WATele-Bridge
Feel free to fork it, tweak it, or use it as a foundation for your own automation ideas!
🤝 Contribute
This is still a work in progress, and contributions are very welcome. Some possible improvements:
- Adding support for two-way sync (WhatsApp → Telegram)
- Deployment scripts (Docker, PM2)
- Better logging and error handling
- Adding the ability to listen from multiple Telegram chats
💡 Final Thoughts
This was a fun experiment that combined multiple APIs and asynchronous programming. If you’ve ever wanted to link two messaging platforms, this project might give you a head start.
