# Setting up Mautrix LinkedIn bridging (optional)
|
|
|
|
<sup>Refer the common guide for configuring mautrix bridges: [Setting up a Generic Mautrix Bridge](configuring-playbook-bridge-mautrix-bridges.md)</sup>
|
|
|
|
The playbook can install and configure [mautrix-linkedin](https://github.com/mautrix/linkedin) for you, for bridging to [LinkedIn](https://www.linkedin.com/) messaging.
|
|
|
|
See the project's [documentation](https://docs.mau.fi/bridges/go/linkedin/index.html) to learn what it does and why it might be useful to you.
|
|
|
|
>[!NOTE]
|
|
> LinkedIn keeps its messaging function behind a login wall and does not provide a usable public API, so using this bridge requires you to manually copy cookies on a web browser for logging in. Refer to [this section](#usage) below for details.
|
|
|
|
## Prerequisite
|
|
|
|
### Uninstalling `beeper-linkedin`
|
|
|
|
If `beeper-linkedin` bridge is enabled on your host, you need to uninstall it first, since it claims the `@linkedinbot` username and `@linkedin_*` user range as exclusive appservice namespaces, which will cause conflicts with `mautrix-linkedin`.
|
|
|
|
To uninstall the bridge, set `matrix_bridge_beeper_linkedin_enabled: false` and re-run the playbook. The playbook refuses to install `mautrix-linkedin` until `beeper-linkedin` is uninstalled.
|
|
|
|
### Enable Appservice Double Puppet (optional)
|
|
|
|
If you want to set up [Double Puppeting](https://docs.mau.fi/bridges/general/double-puppeting.html) (hint: you most likely do) for this bridge automatically, you need to have enabled [Appservice Double Puppet](configuring-playbook-appservice-double-puppet.md) for this playbook.
|
|
|
|
See [this section](configuring-playbook-bridge-mautrix-bridges.md#set-up-double-puppeting-optional) on the [common guide for configuring mautrix bridges](configuring-playbook-bridge-mautrix-bridges.md) for details about setting up Double Puppeting.
|
|
|
|
## 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_bridge_mautrix_linkedin_enabled: true
|
|
```
|
|
|
|
### Extending the configuration
|
|
|
|
There are some additional things you may wish to configure about the bridge.
|
|
|
|
<!-- NOTE: relay mode is not supported for this bridge -->
|
|
See [this section](configuring-playbook-bridge-mautrix-bridges.md#extending-the-configuration) on the [common guide for configuring mautrix bridges](configuring-playbook-bridge-mautrix-bridges.md) for details about variables that you can customize and the bridge's default configuration, including [bridge permissions](configuring-playbook-bridge-mautrix-bridges.md#configure-bridge-permissions-optional), [encryption support](configuring-playbook-bridge-mautrix-bridges.md#enable-encryption-optional), [bot's username](configuring-playbook-bridge-mautrix-bridges.md#set-the-bots-username-optional), etc.
|
|
|
|
## Installing
|
|
|
|
After configuring the playbook, run it with [playbook tags](playbook-tags.md) as below:
|
|
|
|
<!-- NOTE: let this conservative command run (instead of install-all) to make it clear that failure of the command means something is clearly broken. -->
|
|
```sh
|
|
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
|
|
```
|
|
|
|
The shortcut commands with the [`just` program](just.md) are also available: `just install-all` or `just setup-all`
|
|
|
|
`just install-all` is useful for maintaining your setup quickly ([2x-5x faster](../CHANGELOG.md#2x-5x-performance-improvements-in-playbook-runtime) than `just setup-all`) when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed. Note these shortcuts run the `ensure-matrix-users-created` tag too.
|
|
|
|
## Usage
|
|
|
|
Start a chat with `@linkedinbot:example.com` (where `example.com` is your base domain, the bare one without the `matrix.` prefix) and send `login`.
|
|
|
|
### Logging in
|
|
|
|
To log in, you need to sign in to LinkedIn with a web browser and hand one of the requests it makes to the bot. Because the bridge presents itself as Chrome on Linux, the request needs to come from **Chrome or a Chrome-based browser**.
|
|
|
|
>[!WARNING]
|
|
> LinkedIn ties the session to the browser that made the request and rejects it when it is replayed under a different user-agent. A request copied from Firefox therefore results in a session that stops working immediately, without an error message.
|
|
|
|
You need to follow these steps to log in:
|
|
|
|
1. Open [linkedin.com](https://www.linkedin.com/) in a private/incognito window on Chrome / a Chrome-based browser
|
|
2. Sign in to LinkedIn
|
|
3. Open your browser's devtools (F12) and go to the Network tab
|
|
4. Filter for `graphql`
|
|
5. Right-click any one of those requests, then "Copy" and "Copy as cURL"
|
|
6. Paste the output into the chat with the bot and send it
|
|
|
|
The bridge's [official Authentication guide](https://docs.mau.fi/bridges/go/linkedin/authentication.html) walks the same steps with screenshots.
|
|
|
|
Once you log in, the bridge builds portal rooms for your recent conversations and carries messages both ways.
|
|
|
|
**💡 Notes:**
|
|
|
|
- The request contains a login session, which LinkedIn may expire at any time. When the bridge goes quiet, log in again by following the steps above.
|
|
- If you would rather not retrieve the request yourself, you may wish to take a look at [mautrix-manager](https://github.com/mautrix/manager).
|
|
|
|
## Troubleshooting
|
|
|
|
### The bot does not respond after you send it the cURL output
|
|
|
|
This most likely means that you have obtained the request with a browser other than Chrome or a Chrome-based one. LinkedIn silently discards a session replayed under a different user-agent. Follow the login steps above again, this time using Chrome or a Chrome-based browser.
|
|
|
|
### The bridge worked before, but has gone quiet
|
|
|
|
Your LinkedIn session has most likely expired. Send `login` to the bot and follow the login steps above again.
|
|
|
|
### Other issues
|
|
|
|
As with all other services, you can find the logs in [systemd-journald](https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html) by logging in to the server with SSH and running `journalctl -fu matrix-mautrix-linkedin`.
|
|
|
|
### Increase logging verbosity
|
|
|
|
The default logging level for this component is `warn`. If you want to increase the verbosity, add the following configuration to your `vars.yml` file and re-run the playbook:
|
|
|
|
```yaml
|
|
# Valid values: fatal, error, warn, info, debug, trace
|
|
matrix_bridge_mautrix_linkedin_logging_level: 'debug'
|
|
```
