Event Dispatcher

No UI

This plugin informs external systems about changes in CELUM. Various filters allow you to restrict the scope of the events, so that only relevant events are dispatched. Both the filters and the dispatcher allow for custom implementations through the use of beans. By default we ship simple GET and POST implementations for use in Webhooks.
