While Calendly's Salesforce integration will automatically create a new lead and event when a Calendly meeting is scheduled and tie it to the Salesforce user by default, the flow is entirely customizable to meet your organizations specific needs.
Note: Customizations should only be made with the support of your organization's Salesforce Administrator.
