πŸš€ WATele-Bridge: A Telegram ↔ WhatsApp Bridge

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? πŸ‘‰ WATele-Bridge – a simple, self-hosted bridge between Telegram and WhatsApp.

πŸ”§ How It Works

The project has two main parts:

  1. 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.
  1. 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 β†’ 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.

πŸš€ Try It Yourself

You can self-host the project with the instructions in the repo:
πŸ‘‰ 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 β†’ Telegram)
  • Deployment scripts (Docker, PM2)
  • Better logging and error handling
  • Adding the ability to listen from multiple Telegram chats

πŸ’‘ 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.
