Basic properties
The basic properties for a message start event are:
| Property | Required | Description |
|---|---|---|
| ID | Required | The unique identifier for the message start event. This is system generated and cannot be altered, for example: StartEvent_1w29b3h |
| Name | Optional | The name of the message start event. This will be displayed on the canvas. |
| Documentation | Optional | A free text description of what the message start event does. |
Form name
An optional form can be used to begin a process. The form must exist within the same project as the process definition to be selected. Select a form from the drop-down list, or create a new form using the + symbol.
Once a form has been selected, it can be edited using the Open Form symbol.
Mapping type
The mapping type sets how data is passed between the message start event and the process. There are five options for sending this data. The default value is Send no variables.
Message
A message needs to be defined for the message start event to catch when it is thrown. A previously created Message can be selected from the drop-down list in its properties, or a new one created using the + symbol. A Message name and payload can then be set.
