Payroll Automation

PayRun.io provides a HMRC recognised UK payroll and Auto Enrolment API (Application Programming Interface).

The API enables software providers to deeply integrate UK payroll and auto enrolment functionality within their software products without the ongoing overhead of maintaining compliance year on year.

It has been one of our core aims to make using this API as simple as possible by abstracting away the complexity through providing a clean RESTful architecture.

To get started we suggest first reading Creating Your First App and exploring the API's capabilities using our Open API (swagger) tool.
