Employee Time Tracking System with GPT-4o Reports & Gmail Notifications

Overview This workflow acts as an AI-powered smart time tracker for employees or personal use.
It records work sessions via a webhook, logs start/end/break times into n8n Data Tables,
and uses OpenAI to automatically summarize working patterns and send reminders or monthly reports via Gmail.

How It Works Webhook /track-time → Receives a POST request with a method (start, break, or end) and duration if applicable.
Switch Logic → Directs the request to create or update the appropriate record in your Data Table.
Data Tables → Store timestamps, break durations, and worker IDs in a secure local table.
Schedule Triggers
Daily (10:00) → Checks if today’s shift was not started and sends a reminder.
Monthly (Day 1, 06:00) → Compiles last month’s working data and sends an AI report to management.
OpenAI Analysis
Summarizes working hours and productivity trends.
Detects missed clock-ins or irregular patterns.
Gmail Integration → Sends formatted daily or monthly reports to both employees and supervisors.

Example Webhook Requests Start work POST /track-time { "method": "start", "headers": { "id": "EMP001" } }

Log a break POST /track-time { "method": "break", "duration": 15, "headers": { "id": "EMP001" } }

End work POST /track-time { "method": "end", "headers": { "id": "EMP001" } }
