This workflow automates the process of tracking construction workers’ check-ins and check-outs using GPS data by employing an n8n webhook, geofence validation, data logging, and notifications. When a worker submits their location via a web form or mobile app, the workflow kicks off with a webhook that captures the input. A function node then validates whether the employee’s GPS coordinates are within a predefined geofenced construction site area using the Google Maps API. If the location is valid, the workflow formats the attendance log, appends it to a Google Sheet for record-keeping, and sends a confirmation email to relevant stakeholders. If the location is outside the geofence, an alert email can be triggered instead. This setup is ideal for construction companies wanting real-time, location-based attendance monitoring.
Key steps include:
1. Webhook receives GPS data and worker info.
2. Validation of location within geofence and proper log formatting.
3. Appending attendance data to Google Sheets.
4. Sending notification emails for confirmation or alert.
This workflow improves accuracy, transparency, and automation in attendance management, reducing manual checks or manual data entry, and ensuring workers are present at the designated site.
