📡 What is eSSL Cloud API?

☁️➡️🖥️

Centralized Attendance Gateway

eSSL Cloud API is a RESTful web service that exposes attendance logs collected from eSSL biometric/face machines installed at different branches (offices, factories, warehouses). The cloud aggregates data in real time and makes it accessible via standard HTTP endpoints (JSON/XML).

Third‑party HRMS software can pull punch-in/out records, user details, and shift logs — or eSSL Cloud can push data to external HRMS by calling their APIs.

🔗🤝

Two‑Way Integration Flexibility

Pull Mode: HRMS fetches attendance on demand or via scheduled cron jobs.
Push Mode: eSSL Cloud instantly sends each punch to your software using webhooks or by consuming your HRMS API endpoints.
Perfect for real‑time absentee alerts and automated payroll.

🚀 Why eSSL Cloud API?

⚡

Eliminate Manual Data Entry

Stop exporting CSV files from devices manually. The API automates attendance sync, reducing human errors and saving dozens of hours every month. Perfect for organisations with 500+ employees across multiple cities.

🌍

Unified Multi‑Location Management

Manage attendance from Pune, Mumbai, Delhi, or any location in one place. The eSSL Cloud aggregates data from all face and fingerprint devices, and the API gives you a unified view – ideal for HR teams and regional admins.

🧾

Real‑time Payroll & Compliance

Integrate with your existing HRMS (SAP, Zoho, Keka, Greythr, custom ERP). Attendance data flows automatically into salary calculations, leave policies, and overtime reports. Reduce discrepancies and improve employee trust.

🔐

Secure & Scalable

API key authentication, HTTPS encryption, rate limiting, and optional IP whitelisting. Designed for enterprises that need reliability and audit trails. Handles thousands of punches per minute without downtime.

✅ Key Benefits of eSSL Cloud API

  • Zero infrastructure maintenance – fully cloud based, no on‑premise middleware.
  • Works with any HRMS – REST API can be consumed by PHP, Java, Python, .NET, Node.js.
  • Real‑time push via webhooks – get instant notifications when employees punch.
  • Historical data sync – retrieve attendance logs from any date range (up to 1 year).
  • Employee master sync – fetch/update user bio-data, department mapping.
  • Cost effective – reduces manual effort, custom integrations and middleware costs.
  • Multi‑tenant ready – manage multiple client organisations from one API dashboard.
  • High availability – 99.9% uptime SLA with redundant servers.
  • Customizable data fields – map your HRMS employee IDs with device userIds.
  • Automatic device health check – API returns device status and connectivity alerts.
  • GDPR & local compliance – audit trails and data retention policies configurable.

❓ Frequently Asked Questions (FAQ)

🔹 What exactly is eSSL Cloud API?
It’s a REST API that allows third‑party HRMS/ERP software to communicate with eSSL’s cloud platform. You can fetch employee attendance from multiple eSSL face/fingerprint devices located at different sites, and also push data to external systems. Designed for automated, real‑time integration.
🔹 How does eSSL Cloud push data to third-party HRMS?
eSSL Cloud can be configured to call external APIs (webhooks) whenever an attendance event occurs. You provide the endpoint URL of your HRMS (e.g., https://yourhrms.com/api/attendance) and the cloud will forward each punch record via POST request. Alternatively, your HRMS can pull data periodically using GET calls.
🔹 Which eSSL biometric devices are compatible?
All eSSL devices with cloud connectivity: eSSL FaceX series (X6, X9, M18, M30), fingerprint terminals (K30, K40, iClock 280/580, C3 series) and any device that supports the eSSL Cloud protocol. Legacy devices can be upgraded with a cloud-enable module.
🔹 Do I need to be a developer to use the API?
Basic REST knowledge helps, but we provide SDK samples for PHP, Python, JavaScript, and Postman collections. Your internal HRMS team or system integrator can implement the connection. We also offer technical support during integration.
🔹 Is there any limit on API calls?
Standard plans include 60,000 API calls per month (more than enough for most midsize enterprises). For large deployments with 20+ devices, we provide custom enterprise quotas and unlimited plans.
🔹 How secure is the attendance data?
All communication is over HTTPS (TLS 1.2+). Authentication uses API keys that can be rotated. Optional IP whitelisting and OAuth2 support available for enterprise clients. Data is encrypted at rest and in transit.
