Event Parameters

Events represent changes that occur in components. Each standard event occurs when it is caused by an action. For example, the User Create event occurs when a new user is added using the Add User user interface or the createUser web service method. You can optionally add custom events.

Each event type may have parameters associated with it. When an event occurs, the parameter values reflect the context of the event. For example, when the User Create event occurs, the associated parameter named $user_id$ contains the User ID value for the new user just created.

Event parameter values can be used in rule filters and rule actions.

Most parameters for event types are intuitive; however, the parameters in this section require explanation.
