Start events

A start event defines how a process begins. A diagram must include exactly one start event.

Event typeIconMeaning
None Used for manual starts or when the trigger is defined outside the BPMN model.
Message message start eventIndicates the process is triggered by an incoming message. Often used in called processes.
Timer timer star eventsIndicates the process starts at a specific time or after a delay. Useful for scheduled operations.

A process in Maestro must include at least one start event. A Maestro process must include at least one start event. You can model multiple start events in the same process to support different entry points.

When you have multiple start events and you want to do a Debug, right-click the start event you want to test and select Test.

When you deploy a process, you can set a default entry point (a start event). Orchestrator uses this start event when you start the process without explicitly specifying one. You can still run or debug from any other start event by selecting it at run time.

Note: A process in Maestro must include at least one start event. You can model multiple start events in the same process to support different entry points (for example FHTTP/API), schedule, or manual Use sub-processes to model additional entry points.

For more details about the BPMN elements supported in Maestro, see BPMN support.
