Simple Telegram Bot

A simple relay communication between Rocket.Chat and Telegram is possible by configuring a basic bot. The guide below shows a community example of how this can be achieved with webhooks.

This gives you the possibility of relaying messages between Telegram and Rocket.Chat in a specified room of your choice.

This integration is not suitable for Omnichannel Conversations. Consult the Telegram App for managing your Omnichannel conversations with Telegram. Workspaces subscribed to any of Rocket.Chat's premium plans can install the Telegram App, which comes with additional functionalities and Omnichannel features.

Getting Started

Make sure Your Rocket.Chat workspace URL is publicly available.

  1. Log in to your Telegram account on your mobile or using a browser.

  2. Add and open a conversation with the user BotFather.

  3. Click start.

  4. Send /newbot to start creating a new bot.

  5. Follow the instructions to continue.

    • Set the bot's username. Telegram successfully creates the bot and shows how to access it.

  6. Copy the token provided, it is needed for the configuration.
