This n8n workflow streamlines the process of scheduling appointments by combining user-friendly multi-step forms, AI-based inquiry classification, and human approval mechanisms. It begins with a form trigger that collects essential user details and their enquiry. An AI-powered text classifier assesses the enquiry to determine its relevance or need for an appointment. The workflow then guides the user through a second form to specify the preferred date and time, including terms and conditions for booking. Once the user submits all the details, an acknowledgment email is sent, and an approval request is automatically sent to an admin via Gmail’s ‘Wait for Approval’ feature. If approved, the system creates a Google Calendar event for the appointment; if declined, a rejection email is sent to the user. This workflow is ideal for organizations needing manual oversight in scheduling while maintaining a smooth user experience.
