The user ID of the new bridge (mautrix-meta) is different from that of the old bridge (mautrix-facebook). It is slightly confusing, and the note should help migration. Signed-off-by: Suguru Hirahara <acioustick@noreply.codeberg.org>

# Setting up Messenger bridging via Mautrix Meta (optional)
|
|
|
|
The playbook can install and configure the [mautrix-meta](https://github.com/mautrix/meta) Messenger/Instagram bridge for you.
|
|
|
|
Since this bridge component can bridge to both [Messenger](https://messenger.com/) and [Instagram](https://instagram.com/) and you may wish to do both at the same time, the playbook makes it available via 2 different Ansible roles (`matrix-bridge-mautrix-meta-messenger` and `matrix-bridge-mautrix-meta-instagram`). The latter is a reconfigured copy of the first one (created by `just rebuild-mautrix-meta-instagram` and `bin/rebuild-mautrix-meta-instagram.sh`).
|
|
|
|
This documentation page only deals with the bridge's ability to bridge to Facebook Messenger. For bridging to Instagram, see [Setting up Instagram bridging via Mautrix Meta](configuring-playbook-bridge-mautrix-meta-instagram.md).
|
|
|
|
|
|
## Migrating from the old mautrix-facebook bridge
|
|
|
|
If you've been using the [mautrix-facebook](./configuring-playbook-bridge-mautrix-facebook.md) bridge, it's possible to migrate the database using [instructions from the bridge documentation](https://docs.mau.fi/bridges/go/meta/facebook-migration.html) (advanced).
|
|
|
|
Then you may wish to get rid of the Facebook bridge. To do so, send a `clean-rooms` command to the management room with the old bridge bot (`@facebookbot:example.com`). It gives you a list of portals and groups of portals you may purge. Proceed with sending commands like `clean recommended`, etc.
|
|
|
|
Then, consider disabling the old bridge in your configuration, so it won't recreate the portals when you receive new messages.
|
|
|
|
**Note**: the user ID of the new bridge bot is `@messengerbot:example.com`, not `@facebookbot:example.com`. After disabling the old bridge, its bot user will stop responding to a command.
|
|
|
|
## Adjusting the playbook configuration
|
|
|
|
To enable the bridge, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```yaml
|
|
matrix_mautrix_meta_messenger_enabled: true
|
|
```
|
|
|
|
Before proceeding to [re-running the playbook](./installing.md), you may wish to adjust the configuration further. See below.
|
|
|
|
### Bridge mode
|
|
|
|
As mentioned above, the [mautrix-meta](https://github.com/mautrix/meta) bridge supports multiple modes of operation.
|
|
|
|
The bridge can pull your Messenger messages via 3 different methods:
|
|
|
|
- (`facebook`) Facebook via `facebook.com`
|
|
- (`facebook-tor`) Facebook via `facebookwkhpilnemxj7asaniu7vnjjbiltxjqhye3mhbshg7kx5tfyd.onion` ([Tor](https://www.torproject.org/)) - does not currently proxy media downloads
|
|
- (default) (`messenger`) Messenger via `messenger.com` - usable even without a Facebook account
|
|
|
|
You may switch the mode via the `matrix_mautrix_meta_messenger_meta_mode` variable. The playbook defaults to the `messenger` mode, because it's most universal (every Facebook user has a Messenger account, but the opposite is not true).
|
|
|
|
Note that switching the mode (especially between `facebook*` and `messenger`) will intentionally make the bridge use another database (`matrix_mautrix_meta_facebook` or `matrix_mautrix_meta_messenger`) to isolate the 2 instances. Switching between Tor and non-Tor may be possible without dataloss, but your mileage may vary. Before switching to a new mode, you may wish to de-configure the old one (send `help` to the bridge bot and unbridge your portals, etc.).
|
|
|
|
|
|
### Bridge permissions
|
|
|
|
By default, any user on your homeserver will be able to use the bridge.
|
|
|
|
Different levels of permission can be granted to users:
|
|
|
|
- `relay` - Allowed to be relayed through the bridge, no access to commands
|
|
- `user` - Use the bridge with puppeting
|
|
- `admin` - Use and administer the bridge
|
|
|
|
The permissions are following the sequence: nothing < `relay` < `user` < `admin`.
|
|
|
|
The default permissions are set via `matrix_mautrix_meta_messenger_bridge_permissions_default` and are somewhat like this:
|
|
```yaml
|
|
matrix_mautrix_meta_messenger_bridge_permissions_default:
|
|
'*': relay
|
|
example.com: user
|
|
'{{ matrix_admin }}': admin
|
|
```
|
|
|
|
If you don't define the `matrix_admin` in your configuration (e.g. `matrix_admin: @user:example.com`), then there's no admin by default.
|
|
|
|
You may redefine `matrix_mautrix_meta_messenger_bridge_permissions_default` any way you see fit, or add extra permissions using `matrix_mautrix_meta_messenger_bridge_permissions_custom` like this:
|
|
|
|
```yaml
|
|
matrix_mautrix_meta_messenger_bridge_permissions_custom:
|
|
'@YOUR_USERNAME:example.com': admin
|
|
```
|
|
|
|
You may wish to look at `roles/custom/matrix-bridge-mautrix-meta-messenger/templates/config.yaml.j2` to find more information on the permissions settings and other options you would like to configure.
|
|
|
|
## Installing
|
|
|
|
After configuring the playbook, run the [installation](installing.md) command: `just install-all` or `just setup-all`
|
|
|
|
## Set up Double Puppeting
|
|
|
|
If you'd like to use [Double Puppeting](https://docs.mau.fi/bridges/general/double-puppeting.html) (hint: you most likely do), you have 2 ways of going about it.
|
|
|
|
### Method 1: automatically, by enabling Appservice Double Puppet
|
|
|
|
The bridge will automatically perform Double Puppeting if you enable the [Appservice Double Puppet](configuring-playbook-appservice-double-puppet.md) service for this playbook.
|
|
|
|
Enabling [Appservice Double Puppet](configuring-playbook-appservice-double-puppet.md) 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.
|
|
|
|
### 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 (see [Usage](#usage)).
|
|
|
|
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](obtaining-access-tokens.md).
|
|
|
|
- send the access token to the bot. Example: `login-matrix MATRIX_ACCESS_TOKEN_HERE`
|
|
|
|
- make sure you don't log out the session for which you obtained an access token some time in the future, as that would break the Double Puppeting feature
|
|
|
|
|
|
## Usage
|
|
|
|
You then need to start a chat with `@messengerbot:example.com` (where `example.com` is your base domain, not the `matrix.` domain). Note that the user ID of the bridge's bot is not `@facebookbot:example.com`.
|
|
|
|
You then need to send a `login` command and follow the bridge bot's instructions.
|
|
|
|
Given that the bot is configured in `messenger` [bridge mode](#bridge-mode) by default, you will need to log in to [messenger.com](https://messenger.com/) (not `facebook.com`!) and obtain the cookies from there as per [the bridge's authentication instructions](https://docs.mau.fi/bridges/go/meta/authentication.html).
