To trigger the workflow, execute the PostEvent JavaScript function. This function lets you pass variables with the values of your choice and use them in the triggered workflow.

The PostEvent function can be executed either from another workflow or from an API call.

• To trigger an External signal activity from a workflow, execute the PostEvent function from the Initialization script pane, accessible from the activity’s Execution options. For the JavaScript code activity, execute the function from the activity’s script.

  The syntax is as follows:

  code language-none
  xtk.workflow.PostEvent("<workflow-internal-name>","<signal-activity-name>","",<variables <variable-name>="<value>"/>, false);

• To trigger an External signal activity from an API call, follow the steps detailed in the Campaign API documentation. Learn how to use the static PostEvent method.
