If I build my own GPS tracking software, how can I connect it with greytHR’s attendance or location-based features so that they work together?

Hi @Suheb ,

That’s a very good, practical question :ok_hand:. If you build your own GPS tracking software and want it to integrate with greytHR’s attendance or location-based features, here’s how you can make them work together:

:link: 1. API Integration

  • Check greytHR APIs: greytHR provides APIs for Attendance, Leave, and Employee Data. You’d use these to push location or punch-in/out data from your GPS software into greytHR.

  • Flow example:

    • Your GPS app captures employee location & time.

    • It formats that data (employee ID, timestamp, location coordinates).

    • Through API, you send this to greytHR’s attendance endpoint as a “punch-in” or “punch-out.”

  • Benefit: greytHR continues to be the system of record for attendance, while your GPS app becomes the source of accurate geo-data.

:round_pushpin: 2. Geo-fencing & Validation

  • Your GPS software can validate whether an employee is within the office/site geo-fence at the time of punch.

  • Only after validation, send the attendance punch to greytHR.

  • This way, greytHR’s attendance reports stay accurate without building geo-fencing logic twice.

:gear: 3. Webhook/Automation

  • If greytHR allows webhooks (or scheduled imports), you can set your system to send attendance logs periodically.

  • For example, every hour/day your GPS system pushes attendance records to greytHR.

:bar_chart: 4. Reports & Dashboards

  • greytHR already has reports and dashboards for attendance.

  • By integrating, your custom GPS tracking data flows directly into greytHR’s existing dashboards—no need to rebuild reports separately.

:warning: Things to Keep in Mind

  • API Documentation & Access: You’ll need greytHR’s developer API docs (they are available to customers via request).

  • Employee IDs Matching: Ensure employee IDs in your GPS system match greytHR’s employee master, otherwise syncing will fail.

  • Compliance & Privacy: Since GPS data is sensitive, ensure consent, secure data storage, and GDPR/IT compliance.

  • Fallback: If API is unavailable, you could use CSV uploads to greytHR’s attendance module (semi-automated integration).
