The commercial PaymentEvolution Payroll web services API is available for integration with your custom application or service. From simple payroll deduction calculations to complex benefits and custom earnings - we work with you to implement the set of services you need.
For simple calculations you can embed our skinnable widget in your site. Contact us for details and licensing terms.
You'll need an authorized API account which you can register for by contacting us. Calculations are performed using pre-paid bundles:
If you need a larger bundle, please get in touch. At this time, we do not offer smaller packages.
Bundles are payable online or through terms established with us
Bundles expire after one year, when the bundle term expires, or when the number of calculations have run out.
Unused calculations may not be carried forward
Each call made to the API counts as one calculation, regardless of the number of results returned by the call
You may check the number of calculations remaining in your bundle via the API
