I have my API key. With in the dialer is a lot of the information on the client. I need to pass all of this onto my page for zoho. The values are different with each client.

Zoho Field First Name

Dialer Field ($first_name), Last Name is ($last_name), Phone is ($primary_phone)

Can someone point me in the direction of how to do this with some examples say for first, last and phone?
