Start – Every workflow contains exactly one Start step; all workflows begin at the Start step.

Finish – Every workflow contains exactly one Finish step; all workflows end at the Finish step.

Cancel – Every workflow contains a cancel step, which is executed when a task is canceled.

Auto Error – Workflows that contain one or more Automatic steps must contain an Auto Error step. When a task fails on an automatic step, it is assigned to Auto Error. This helps you to determine who should be notified when an error occurs in an automatic action.
