Is it possible to delete child records when the parent record is deleted?

Is it possible to delete child records when the parent record is deleted?

We created two custom modules in Zoho CRM. One is a parent record and the other is a child record (i.e. has a lookup field that references the parent). A parent can have multiple children. Is it possible to automatically delete the child records when the parent is deleted? I found an example to do what I need in the Deluge documentation: https://www.zoho.com/deluge/help/data-access/delete-records.html#example4. But at the top of the page it says "Note: This task is applicable only to Zoho Creator". We don't have a Zoho Creator subscription so this script doesn't work for us.
