n8n Clinic Appointment Workflow: WhatsApp AI + Stripe + Sheets

Book, pay, and get reminders automatically—right from WhatsApp

The n8n Clinic Appointment Workflow: WhatsApp AI + Stripe + Sheets automates your clinic’s appointment lifecycle end-to-end. Patients book through an AI chat on WhatsApp, payments are processed with Stripe, and daily WhatsApp reminders help reduce no-shows—all tracked in a simple Google Sheets database.

What this workflow does

• Conversational AI booking: A Google Gemini-powered AI assistant guides patients through booking, rescheduling, and canceling in a natural chat experience.
• Smart scheduling with conflict prevention: The workflow checks available time slots using your working hours and existing appointments stored in Google Sheets, preventing double-bookings.
• Automated daily reminders: A daily trigger sends WhatsApp appointment reminders to patients for that day, improving attendance.
• Seamless payments: When a patient completes an online payment, the workflow integrates with Stripe and sends a confirmation message after successful payment.
• Centralized management in Google Sheets: A single Google Sheet with separate tabs for Patients, Appointments, and Configuration keeps operations transparent.
• Instant updates for rescheduling/cancellations: Any changes made through the WhatsApp chat are reflected immediately in your Google Sheets records.

Use cases

• Independent practitioners who want fewer calls and a smoother booking process.
• Clinics that need reliable appointment reminders without manual outreach.
• SaaS operators and automation engineers building a WhatsApp-based scheduling system with Stripe payments.
