Send Patient Condition Updates with Google Sheets, Email & WhatsApp Alerts

This automated n8n workflow reads patient data from Google Sheets daily at 8 AM, sends email and WhatsApp reports to doctors, alerts staff for critical patients, and logs activities back to sheets.

Good to Know

• Runs daily at 8 AM via cron trigger.
• Filters active patients only.
• Requires Google service account, Gmail app password, and WhatsApp API token.
• Logs all sent reports in a dedicated sheet.

How It Works

• Cron Trigger - Schedules daily run at 8 AM.
• Google Sheets (Read) - Fetches patient data from "Patients" sheet.
• Filter Node - Selects active patients.
• Code Node - Processes data, creates report content, checks for critical conditions.
• Email Send Node - Sends reports to doctors via Gmail.
• HTTP Request Node - Sends WhatsApp messages.
• Filter Critical - Identifies critical patients.
• Critical Alert Email - Notifies hospital staff.
• Google Sheets (Write) - Logs reports to "Reports_Log" sheet.
