Setting up Appservices

Getting help

If you run into any problems while setting up an Appservice, write an email to timo@koesters.xyz, ask us in #conduit:matrix.org or open an issue on GitLab.

Set up the appservice - general instructions

Follow whatever instructions are given by the appservice. This usually includes downloading, changing its config (setting domain, homeserver url, port etc.) and later starting it.

At some point the appservice guide should ask you to add a registration yaml file to the homeserver. In Synapse you would do this by adding the path to the homeserver.yaml, but in Conduit you can do this from within Matrix:

First, go into the #admins room of your homeserver. The first person that registered on the homeserver automatically joins it. Then send a message into the room like this:

@conduit:your.server.name: register-appservice
```
paste
the
contents
of
the
yaml
registration
here
```

You can confirm it worked by sending a message like this: @conduit:your.server.name: list-appservices

The @conduit bot should answer with Appservices (1): your-bridge

Then you are done. Conduit will send messages to the appservices and the appservice can send requests to the homeserver. You don't need to restart Conduit, but if it doesn't work, restarting while the appservice is running could help.

Appservice-specific instructions

Remove an appservice

To remove an appservice go to your admin room and execute

@conduit:your.server.name: unregister-appservice <name>

where <name> one of the output of list-appservices.

Tested appservices

These appservices have been tested and work with Conduit without any extra steps:

mautrix-signal

There are a few things you need to do, in order for the Signal bridge (at least up to version 0.2.0) to work. How you do this depends on whether you use Docker or virtualenv to run it. In either case you need to modify portal.py. Do this before following the bridge installation guide.

Create a copy of portal.py. Go to portal.py at mautrix-signal (make sure you change to the correct commit/version of mautrix-signal you're using) and copy its content. Create a new portal.py on your system and paste the content in.
Patch the copy. Exact line numbers may be slightly different, look nearby if they don't match:

Line 1020

--- levels.users[self.main_intent.mxid] = 9001 if is_initial else 100
+++ levels.users[self.main_intent.mxid] = 100 if is_initial else 100

Between lines 1041 and 1042 add a new line:

    "type": str(EventType.ROOM_POWER_LEVELS),
+++ "state_key": "",
    "content": power_levels.serialize(),

Deploy the patch. This is different depending on how you have mautrix-signal deployed:

[If using virtualenv] Copy your patched portal.py to ./lib/python3.7/site-packages/mautrix_signal/portal.py (the exact version of Python may be different on your system).
[If using Docker] Map the patched portal.py into the mautrix-signal container:

```yaml
volumes:
  - ./your/path/on/host/portal.py:/usr/lib/python3.9/site-packages/mautrix_signal/portal.py
```

Now continue with the bridge installation instructions and the general bridge notes above.
