Zuant is able to send leads to Pardot via an HTTP Post. You will need to work with your internal Salesforce Team and with your Zuant Customer Success Manager to get everything up and running.
Our Pardot Integration Guide shows you how this works and the information you will need to get started.
Please Note: Integration with Pardot is only available with the Pro and Enterprise Packages. If you are on a Classic Package and would like to integrate with Pardot, you will need to discuss adding this as a Bolt-On with your dedicated Customer Success Manager.
