Automated WhatsApp Appointment Notification System

This n8n workflow automates the process of managing WhatsApp-based appointment notifications and responses. It integrates WhatsApp, Google Sheets, and scheduling nodes to streamline communication between users and service providers. The workflow starts with a Schedule Trigger to periodically check for new Google Form responses related to appointments. When a new response is detected, it verifies user consent and logs the data in Google Sheets. Alternatively, it listens for incoming WhatsApp messages via a WhatsApp Trigger, stores user messages, and supports automated replies. The system sends appointment reminders or responses through WhatsApp templates, updating message statuses and ensuring continuous communication. Practical use cases include businesses scheduling appointments, sending reminders, and maintaining chat logs with clients via WhatsApp.
