In conjunction with ProcessMaker version 4.1, configure webhooks for your BPMN 2.0 signals. That signal triggers when a signal-type BPMN 2.0 element in a Process's Request calls it or an event in a subscribing ProcessMaker asset occurs. For example, a ProcessMaker Collection can trigger different signals when a record in that Collection is created, edited, or deleted, respectively. All signals are managed from the Signals page in the Designer top menu. Both BPMN 2.0 signals and ProcessMaker Collection signals are collectively referred to as ProcessMaker Signals.
