+Events are authentik's built-in logging system. Whenever any of the following actions occur, an event is created:
+
+- A user logs in/logs out (including the source, if available)
+- A user fails to login
+- A user sets their password
+
+- A user views a token
+
+- An invitation is used
+
+- A user object is written to during a flow
+
+- A user authorizes an application
+- A user links a source to their account
+
+- A user starts/ends impersonation, including the user that was impersonated
+
+- A policy is executed (when a policy has "Execution Logging" enabled)
+- A policy or property mapping causes an exception
+
+- A configuration error occurs, for example during the authorization of an application
+
+- Any objects is created/updated/deleted
+
+- An update is available
+
+Certain information is stripped from events, to ensure no passwords or other credentials are saved in the log.
+
+If you want to forward these events to another application, simply forward the log output of all authentik containers. Every event creation is logged there.

+## Filtering Events
+
+Starting with authentik 0.15, you can create notification triggers, which can alert you based on the creation of certain events.
+
+Filtering is done by using the Policy Engine. You can do simple filtering using the "Event Matcher Policy" type
+
+![](./event_matcher.png)
+
+An Event has to match all configured fields, otherwise it will not match.
+
+To match events with an "Expression Policy", you can write code like so
+
+```python
+if "event" not in request.context:
+    return False
+
+return ip_address(request.context["evnet"].client_ip) in ip_network('192.0.2.0/24')
+```
+
+## Selecting who gets notified
+
+After you've create the policies to match the events you want, create a "Notification Trigger".
+
+You have to select which group the generated notification should be sent to. If left empty, the trigger will be disabled.
+
+You also have to select which transports should be used to send the Notification.
+A transport with the name "default-email-transport" is created by default. This transport will use the [global email configuration](../installation/docker-compose#email-configuration-optional-but-recommended)

+
+Notifications can be sent to users via multiple mediums. Per default, the [global email configuration](../installation/docker-compose#email-configuration-optional-but-recommended) will be used.
+
+## Generic Webhook
+
+This will send a POST request to the given URL with the following contents:
+
+```json
+{
+    "body": "body of the notification message",
+    "severity": "severity level as configured in the trigger",
+    "user_email": "user's email",
+    "user_username": "user's username",
+}
+```
+
+The `Content-Type` Header is set to `text/json`.
+
+:::warning
+This will send a request for each user of the group selected in the trigger.
+:::
+
+## Slack Webhook
+
+This sends a request using the Slack-specific format. This is also compatible with Discord's Webhooks by appending `/slack`.
