How to set up a Telegram-Mattermost link

We have a Matterbridge service, which enables you to link a Telegram channel or group to a Mattermost channel.

The purpose of this service is to reduce the number of communication tools you have to use.

Rebels who are comfortable with Mattermost can keep in touch with Telegram channels, without having to join the Telegram channel.

Likewise, rebels who do not want to use Mattermost, but want to stick with Telegram can do so, without being in a Telegram only silo.

A group that has a thriving Telegram channel, with some people who do not want to use Mattermost, could set up a two-way Matterbridge link. This enables posts to be made and shared from either platform. Subsequently, members who do use Mattermost can leave the Telegram channel, whilst remaining in the overall conversation.


It is very important that people in the existing channel or group know beforehand if you intend to set up a link to or from Mattermost. You should discuss:

  • whether it is one-way or two-way
  • why you are doing it, and
  • who will get access.

This prior consultation and agreement on how the Matterbridge link will improve communications within the group, will lead to a smoother introduction of the link.

Contact DDAT Team on Mattermost, and ask the admins to set up your bridge. They will need the information detailed below, but they can help you with getting your end set up, if you find the following instructions difficult.

What you need to do first

  1. Carefully consider security - if you link a private Mattermost channel to a Telegram channel, then the content is available to anyone who can get in to the Telegram channel.
  2. Get the Telegram channel or group administrator to join user "XRUKMatterbridge_bot" (our bot) to the Telegram channel or group- see instuctions below.
    If it's a channel rather than a group, set the bot as Administrator - most of the admin permissions can be turned off - a Telegram->Mattermost link only needs to be able to read messages; a two-way link also needs to post messages. (NOTE: see section below for more detail).
  3. Notify the DDAT Team that you have added the bot to your Telegram channel, and request them to set up the Matterbridge link. Include the Telegram channel or group name, the Mattermost Team and Mattermost Channel.
