How to trigger actions

I am writing an internal API to react to triggers from Zuora.  There are multiple triggers where you can define an email or an URL to handle the event.  These are found in the "Setup Profiles, Notifications and Email Templates" section of billing or other modules.


An example, Billing > Setup Profiles, Notifications and Email Templates > Upcoming Renewal | 30 days before auto renewal


What I would like to know is what do i need to do to make the Sandbox trigger this event so I can test the entire cycle from Zuora to my ultimate endpoint?  Are there test modules available to manipulate the sandbox so these events fire upon command (rather than the internal job mechanism)?
