将参数传递给Kentico Marketing Automation工作流

如何将参数传递给营销自动化工作流?

我需要将名为“MeetingId”的参数传递到工作流“MeetingInvitation”。我该怎么做?

        ContactInfo contact = ContactInfoProvider.GetContacts()
                                                    .WhereEquals("ContactEmail", "chamara@e.com")
                                                    .TopN(1)
                                                    .FirstOrDefault();

        // Gets the marketing automation process
        WorkflowInfo process = WorkflowInfoProvider.GetWorkflowInfo("MeetingInvitation", WorkflowTypeEnum.Automation);

        if ((contact != null) && (process != null))
        {
            // Creates an automation manager instance
            AutomationManager manager = AutomationManager.GetInstance(MembershipContext.AuthenticatedUser);
           
            // Starts the process for the contact
            manager.StartProcess(contact, process.WorkflowID);
        }
