In addition to common properties you can also configure the following properties for an automation task;
Event Name
Name of event. Event name can set to a plain text value (Ex: Customer.New) or may contain data template expressions to include data from data model. (Ex: "PaymentComplete.{{Id}}" )
You may also specify multiple event names with semicolon delimited format. (Ex: "Customer.New;Customer.Update.{{Id}}" )
Event Data XPath
XPath of event data to be passed to listeners. If set to empty value root element content is used. You can use $Input xml node variable to access related event data.
Handle Script

If no script defined first action is automatically selected.
Event results are stored in $Handlers named array of work item id numbers. If no listener exists array is empty.
Remarks
Events are processed in synchronous behavior and if any exception occurs transaction is rollbacked.
