Triggers

A trigger starts a flow—for an explanation of what this means, see the chapter overview at . Three triggers are not associated with any target system and are available in every flow:

• Cron Trigger – fires at scheduled times, as defined by a Cron expression.
• Time Trigger – triggers cyclically, either with a start delay or starting at an absolute time.
• Variable Trigger – triggers when a monitored variable changes.

All other triggers are provided by the plug-ins; they are described in their respective plug-in sections. To determine which trigger is suitable for which task, see . To determine which trigger should be used when, see.
