### Create a simple n8n workflow

> [!NOTE]
> You need to enable the `WEBHOOK` plugin first in order to follow this guide. See the [Plugins guide](./PLUGINS.md) for details.  

N8N can be used for more advanced conditional notification use cases. For example, you want only to get notified if two out of a specified list of devices is down. Or you can use other plugins to process the notifiations further. The below is a simple example of sending an email on a webhook.
