Workflow Overview + +This workflow automates the tracking of construction worker attendance through geofencing technology, integrating GPS check-ins with Google Sheets and email notifications. It is designed to receive check-in/out requests with GPS coordinates, validate whether the worker is within a predefined geofenced construction site area, log the attendance data in a Google Sheet, and send email alerts confirming updates or flagging location issues. + +The workflow’s logic is grouped into these main blocks: + +- **1.1 Input Reception:** Receives HTTP POST requests containing worker check-in/out data, including GPS coordinates and worker details. +- **1.2 Geofence Validation & Log Formatting:** Validates if the GPS location falls within the geofence boundary and formats the attendance record. +- **1.3 Attendance Logging:** Appends the validated attendance record to a Google Sheets document. +- **1.4 Notification:** Sends an email notification summarizing the attendance update. + +--- + +### 2.

General Notes & Resources + +| Note Content | Context or Link | +|---------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------| +| Replace placeholder Google Sheet ID and email addresses with real values before deploying. | Critical for successful data logging and notifications. | +| Ensure Google API credentials have Sheets API enabled and OAuth2 consent configured. | Google Sheets Node requirement. | +| SMTP credentials must allow sending from the specified "from" email address. | Email Send Node requirement. | +| Geofence validation logic must be implemented securely within the Function node to prevent spoofing. | Custom JavaScript code or external API calls can be used; test thoroughly. | +| The webhook endpoint URL must be shared securely with mobile app or form sending attendance data. | Prevent unauthorized data submission. | +| Consider adding authentication or validation on the webhook to improve security (not currently included).| Recommended for production deployments. | + +--- + +**Disclaimer:** +The text provided is exclusively derived from an automated workflow created with n8n, a tool for integration and automation.
