PROJECT OVERVIEW
The Smart Appointment Booking & SMS Automation solution was designed to eliminate manual appointment handling and create a fully automated, real-time confirmation system for clinics and service-based businesses.
By integrating a frontend booking form with n8n, Google Sheets, and Twilio , the entire process, from booking submission to SMS confirmation, runs automatically without human intervention.
This ensures better customer experience, reduced operational workload and accurate centralized record management.
OBJECTIVES
THE CHALLENGE
Before automation, appointment booking involved:
This resulted in:
THE SOLUTION ARCHITECTURE (HOW DOES IT WORK?)
We designed a seamless workflow using n8n as the automation engine.
The system connects:
Frontend Form → Webhook → Data Processing → Google Sheets → SMS Confirmation
Each step is triggered automatically in real time.
How does it work?
Step 1: Booking Form (Frontend – Replit)
A simple, user-friendly booking form was built and hosted on Replit.
The form captures: Full Name, Phone Number, Appointment Date, Appointment Time, Notes (optional)
When the user clicks “Book Appointment”, the data is instantly transmitted to the backend automation system.
This removes the need for phone-based booking and manual data entry.
Step 2: Webhook Trigger (Automation Entry Point)
Upon form submission:
A POST request is sent to the n8n webhook URL
Data is transferred in structure JSON format
The webhook acts as the automation trigger, ensuring real-time processing.
Example data received:
Name: Harsh Purohit
Phone: 919876543210
Appointment Date: 2026-01-16
Appointment Time: 14:00
Status: Pending
Notes: General consultation
This structured input ensures clean and predictable automation execution.
Step 3: Smart Data Storage in Google Sheets
After receiving the webhook data, n8n performs:
Record creation for new bookings
Record updates for existing users
Duplicate prevention using name matching logic
All appointment details are stored in Google Sheets, which acts as a centralized live database.
Stored columns include:
Name | Phone | Appointment Date | Appointment Time | Status | Notes
This allows business owners to track appointments in real time without manual updates.
Step 4: Data Validation & Formatting Layer
A JavaScript processing node inside n8n ensures:
Phone numbers are cleaned and validated
Indian numbers are converted to international format (+91XXXXXXXXXX)
24-hour time format is converted into 12-hour format
Appointment date is transformed into readable format
Personalized SMS message is generated dynamically
Example generated message:
“Dear Harsh, your appointment for Friday, January 16, 2026 at 2:00 PM has been successfully booked. We look forward to seeing you!”
This step ensures professional communication and prevents SMS delivery errors.
Step 5: Instant SMS Confirmation via Twilio
The final step integrates with Twilio SMS API.
Once the data is validated:
The SMS is triggered immediately
The customer receives real-time confirmation
The appointment status can be updated automatically
