Create a contact

Create a contact

Adds a person, with name, title, emails, phones and URLs, to a lead and returns the new contact.

A contact belongs to exactly one lead: pass its lead_id. Without one, Close creates a new lead named after the contact. Send emails as objects with an email and an optional type.

Set up

Use the first option your agent supports.
