Automated Email Verification & Digital Health Card Generator

Overview

Transform your clinic's patient check-in process with this fully automated pre-registration system. When patients submit their appointment information through your website, this workflow instantly verifies their email, generates a professional digital health card with a scannable QR code, stores it securely in Google Drive, and sends personalized notifications to both the patient and your reception team—all in under 20 seconds.

What This Workflow Does

This comprehensive automation handles the entire patient pre-check-in journey:

1. Receives Patient Data - Webhook captures form submissions from your website or app with patient details (name, email, phone, appointment date/time, symptoms, age, gender)

2. Validates & Cleans Data - Automatically validates required fields, cleans input data, and generates a unique patient ID with timestamp for tracking

3. Verifies Email Address - Uses VerifiEmail API to ensure email deliverability by checking RFC compliance, MX records, and filtering out disposable/spoof emails

4. Generates QR Code - Creates a unique verification URL and scannable QR code for instant patient identification at reception

5. Builds Professional Health Card - Generates a beautiful, responsive HTML health card featuring:

   • Patient information grid (name, ID, email, phone, age/gender, appointment)
   • Chief complaints/symptoms section
   • Embedded QR code for quick check-in
   • Important appointment instructions
   • Modern gradient design with mobile-responsive layout

6. Converts to PNG Image - Uses HTMLCSSToImg API to convert the HTML card into a high-quality PNG image (900x1200px)

7. Stores in Google Drive - Uploads the health card to an organized "Patients record" folder with patient ID-based naming for easy retrieval

8. Emails Patient - Sends a beautifully formatted email to the patient containing:

   • Their health card as a PNG attachment
   • Appointment details and confirmation
   • Google Drive link for backup access
   • Check-in instructions and preparation tips

9. Notifies Reception Team - Sends real-time Slack message to clinic reception with patient details, verification status, and Drive link

10. Logs to Database - Records complete patient information, timestamps, verification status, and file links in Google Sheets for tracking and analytics

11. Returns Success Response - Sends JSON response back to the website form with patient ID, confirmation, and Drive link
