Update ap_supplier_contacts via an API?

Hello,

In our 12.1.2 EBS instance, we want to update vendor contact information using an Oracle supported API. 

We used ap_vendor_pub_pkg.update_vendor_contact. However, it turns out that this procedure updates only the inactive_date column in the ap_supplier_contacts table (and the who columns). 

The table ap_supplier_contacts has other columns that we would like to update, like mail_stop, first_name and last_name for example. 

Is there another API that we can use to update the table ap_supplier_contacts? Do we need to use hz_party_contact_v2pub.update_org_contact for example?
