Associate a Contact to a Campaign using deluge?

Associate a Contact to a Campaign using deluge?

If I want to add one record to another related list, which zoho function do I use? zoho.updateRelatedRecord is not it I don't think.  I simply want to take a "Contact" and associate it to a "Campaign" using deluge.  Can anyone help?

contactId = 5122008000000796037;
contactMap = Map();
contactId = zoho.crm.getRecordById("Contacts",contactId);
resp = zoho.crm.update....?
