API and Integration Guide

How to integrate ERP AI with payroll partners, biometric devices, finance tools, reporting layers, and custom internal systems through APIs and exports.

This guide describes integration patterns, authentication expectations, entity mapping, webhook considerations, and safe rollout practices for external systems.

Core integration model

Most integrations work best when ERP AI is treated as the system of record for employee identity, organizational hierarchy, approvals, and operational events. External systems then synchronize only the data they truly own, such as accounting journals, biometric punch streams, or vendor payments.

Use stable IDs for employees, departments, projects, tasks, and financial records to avoid duplicate objects during imports and retry flows.

Common integration scenarios

  • Biometric attendance import and reconciliation
  • Expense or payroll journal export to finance software
  • Project and task synchronization for delivery reporting
  • Employee master sync from identity or HR systems
  • Public careers ingestion and application processing

Implementation safeguards

Always test with a sandbox organization first, validate idempotency for retries, and confirm error messages are understandable for non-technical admins. Integration failures should never silently mutate employee state, payroll values, or approval stages.
