Workflow Trigger

The workflow trigger is used to start a workflow from a workflow.

The workflow trigger configuration looks identical to the variables tab of all the other triggers, except a new variable type is added. The "Passed Parameter" type facilitates the passing of variables from the parent to the child.

By clicking on the "add" or green plus, selecting "Passed Parameter", and entering a variable name, you are requiring the parent workflow to pass the indicated variable to the child. If the parent workflow does not have this variable defined, an error will be generated and no workflow will be started.
