An event initiates an action in a process by matching one of the following:
Trigger - Triggers evaluate events to determine whether to start a process or append the event to an existing work item (an instance of a running process). A single event might trigger multiple processes. A combination of events can trigger a single process.
Wait for Event activity - The Wait for Event activity responds to an event that occurs while a process is running. Typically, each adapter has a customized version of the activity to match events from that adapter. For example, if your Workflow Automation environment has multiple adapters, you might see a Wait for Email Event activity or a Wait for AppManager Event activity.
Workflow Automation provides the following event types:
Base event
Named event
Scheduled event
