When a patient submits their information via a web form, the workflow validates their data, verifies their email using VerifiEmail API, generates a unique patient ID, creates a professional health card (PNG format) with an embedded QR code using HTMLCSSToImg API, uploads the card to Google Drive, emails it to the patient with their appointment details, notifies the clinic reception team via Slack, and logs all information to Google Sheets for record-keeping. The entire process completes in 15-20 seconds with full automation.\n\n### Setup steps\n1. **Add Credentials**: Configure VerifiEmail API, HTMLCSSToImg API, Google Drive OAuth2, Gmail OAuth2, Slack OAuth2, and Google Sheets OAuth2 credentials in n8n\n2. **Create Google Drive Folder**: Create a \"Patients record\" folder in Google Drive and note the folder ID \n3. **Setup Google Sheet**: Create a sheet with columns: Timestamp, Patient ID, Name, Email, Phone, Email Verified, Appointment DateTime, Symptoms, Drive Link, Email Sent, Status\n4. **Configure Slack Channel**: Set up a #clinic-reception channel in your Slack workspace\n5. **Test**: Send a test patient registration and verify all steps complete successfully"
