Setting up Mautrix Telegram bridging (optional)

The playbook can install and configure mautrix-telegram for you.

See the project's documentation to learn what it does and why it might be useful to you.

Adjusting the playbook configuration

You'll need to obtain API keys from https://my.telegram.org/apps and then add the following configuration to your inventory/host_vars/matrix.example.com/vars.yml file:

matrix_mautrix_telegram_enabled: true
matrix_mautrix_telegram_api_id: YOUR_TELEGRAM_APP_ID
matrix_mautrix_telegram_api_hash: YOUR_TELEGRAM_API_HASH

Installing

After configuring the playbook, run the installation command: just install-all or just setup-all

Set up Double Puppeting

If you'd like to use Double Puppeting (hint: you most likely do), you have 2 ways of going about it.

Method 1: automatically, by enabling Appservice Double Puppet or Shared Secret Auth

The bridge will automatically perform Double Puppeting if you enable the Appservice Double Puppet service or the Shared Secret Auth service for this playbook.

Enabling Appservice Double Puppet is the recommended way of setting up Double Puppeting, as it's easier to accomplish, works for all your users automatically, and has less of a chance of breaking in the future.

Enabling double puppeting by enabling the Shared Secret Auth service works at the time of writing, but is deprecated and will stop working in the future.

Method 2: manually, by asking each user to provide a working access token

Note: This method for enabling Double Puppeting can be configured only after you've already set up bridging.

When using this method, each user that wishes to enable Double Puppeting needs to follow the following steps:

• retrieve a Matrix access token for yourself. Refer to the documentation on how to do that.

• send login-matrix to the bot and follow instructions about how to send the access token to it

• make sure you don't log out the Mautrix-Telegram device some time in the future, as that would break the Double Puppeting feature

Usage

You then need to start a chat with @telegrambot:example.com (where example.com is your base domain, not the matrix. domain).

If you want to use the relay-bot feature (relay bot documentation), which allows anonymous user to chat with telegram users, add the following configuration to your inventory/host_vars/matrix.example.com/vars.yml file:

matrix_mautrix_telegram_bot_token: YOUR_TELEGRAM_BOT_TOKEN
matrix_mautrix_telegram_configuration_extension_yaml: |
  bridge:
    permissions:
      '*': relaybot  

You might also want to give permissions to administrate the bot:

matrix_mautrix_telegram_configuration_extension_yaml: |
  bridge:
    permissions:
      '@user:example.com': admin  

More details about permissions in this example: https://github.com/mautrix/telegram/blob/master/mautrix_telegram/example-config.yaml#L410

If you like to exclude all groups from syncing and use the Telgeram-Bridge only for direct chats, you can add the following additional playbook configuration:

matrix_mautrix_telegram_filter_mode: whitelist
