Transfer Products from Contacts Module to Custom Module

Good day,

I would like to know if it is possible to transfer associated "Products" from a contact module to a custom Module?

My Script as follows:

contactDetails = zoho.crm.getRecordById("Contacts",contactId);

medpolicynumber = contactDetails.get("Health_Policy_Number");

contemail = contactDetails.get("Email");

contmobile = contactDetails.get("Phone");

contprod = contactDetails.get("Products");

mp = Map();

mp.put("Medical_Policy_Number",medpolicynumber);

mp.put("Email",contemail);

mp.put("Mobile",contmobile);

mp.put("Products5",contprod);

update = zoho.crm.updateRecord("Servicing",serviceId.toLong(),mp);

info mp;

info update;

Kindly note the that all the information on this script transfers perfectly, except for the associated products.

Regards
