NEST web services for payroll integration

We know that effective payroll integration will be critical for many thousands of employers. That’s why we’ve developed web services to streamline the data transfer process.

We’ve listened to payroll industry feedback and worked closely with leading suppliers of payroll packages to design an API that allows seamless data transfer between payroll software to NEST. This is a solution that can be used by any payroll provider or employer.

If you’re a payroll software provider or developer, you can use our technical guides to help you build our new web service functionality.
