# Setting up Mautrix Whatsapp 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-whatsapp](https://github.com/mautrix/whatsapp) for you.
See the project's [documentation](https://docs.mau.fi/bridges/go/whatsapp/index.html) to learn what it does and why it might be useful to you.
## Prerequisite (optional)
### Enable Appservice Double Puppet or Shared Secret Auth
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) or [Shared Secret Auth](configuring-playbook-shared-secret-auth.md) service 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.
**Note**: double puppeting with the Shared Secret Auth works at the time of writing, but is deprecated and will stop working in the future.
## 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_whatsapp_enabled: true
```
### Extending the configuration
There are some additional things you may wish to configure about the 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), [relay mode](configuring-playbook-bridge-mautrix-bridges.md#enable-relay-mode-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,ensure-matrix-users-created,start
```
**Notes**:
- The `ensure-matrix-users-created` playbook tag makes the playbook automatically create the bot's user account.
- 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.
## Usage
To use the bridge, you need to start a chat with `@whatsappbot:example.com` (where `example.com` is your base domain, not the `matrix.` domain).
You can then follow instructions on the bridge's [official documentation on Authentication](https://docs.mau.fi/bridges/go/whatsapp/authentication.html).
Approximately in a minute after logging in, the bridge will create portal rooms for recent chats.
**Note**: your linked devices will be logged out if you dont use your phone for over 14 days (see the official FAQ entry [here](https://faq.whatsapp.com/general/download-and-installation/about-linked-devices)). The bridge will warn you if it doesn't receive any data from the phone over 12 days.
## Troubleshooting
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-whatsapp`.
### 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_mautrix_whatsapp_logging_level: 'debug'
```
