API Documentation

Our API documentation provides the technical information developers need to understand the available endpoints, requests, responses and integration requirements.

The documentation is based on the OpenAPI Specification (OAS), a widely used standard for describing REST APIs. This provides a structured reference that can be used to understand the available API functionality and support the development of integrations.

 

What can you build?

The Crystal Payroll API can support a range of custom integration and automation projects, including:

  • Time and attendance – connect custom timesheet and workforce management applications
  • HR workflows – automate employee and onboarding processes
  • Data synchronisation – exchange authorised employee and payroll information between systems
  • Custom applications – build internal or commercial applications that connect with Crystal Payroll
  • Reporting and data pipelines – move authorised payroll data into other business systems

If you are developing a software product or integration that needs to connect with Crystal Payroll, our developer access process allows us to understand your requirements and provide the appropriate access.
