I've been searching, but have not found the answer to this question. What API do I use to create a customer account contact name and assign a phone number to that contact? I know the API to create the contact phone but the parameters do not contain contact name fields.
You can try the following:
1) Create a contact of relationship between person and customer
2) Create the phone contact details for the relationship of the person as a contact using hz_contact_v2pub.create_contact_point
3) create the cust account role for the contact relationship with the account to indicate account level contact
I am trying to achieve the same thing (Creating Contact for Customer Account) but having hard time finding the right API. I got your points 2 & 3 but have a question on step1 (Create a contact of relationship between person and customer). What is the API for this?. How do we create relationship between Party & Customer?.
