SimplePay provides an API to access and modify payroll information. If you have an in-house system you'd like to integrate with SimplePay, just enable API access and use the supplied secret token with your requests.
Use of the SimplePay API is subject to the API terms and conditions
Read our API docs for currently supported API operations, and get in touch if you'd like to give your input on our evolving API roadmap!
