To authenticate a MailChimp v3.0 connector instance you must register an app with MailChimp. When you authenticate, use the Client Id, Client Secret, and Redirect URI as the API Key, API Secret, and Callback URL. If you plan to monitor events, also set up webhooks by following the steps in Set Up Events.
