An event rule is a mechanism for automatically taking an action (such as running a script or sending a webhook) in response to an event in NetBox. For example, you may want to notify a monitoring system whenever the status of a device is updated in NetBox. This can be done by creating an event for device objects and designating a webhook to be transmitted. When NetBox detects a change to a device, an HTTP request containing the details of the change and who made it be sent to the specified receiver.

See the event rules documentation for more information.
