Unified API

One API to unite every provider

Finch standardizes employment data across every provider. So you don't have to.


What percentage of the market uses Insperity?

Given that Insperity serves over 100,000 customers, and there were 6.1 million employers in the United States as of 2019, Insperity is estimated to serve 1.64% of the U.S. market. 

How can I access the employment data in Insperity?

Insperity’s API is only available to their customers. That means third-party developers need a unified API like Finch to access the employment data housed in their system. 

You won’t be disappointed. By building a single integration with Finch, you unlock access to not only the employment data in Insperity but also customer data housed in over 200 other employment systems.

Does Insperity have a public API?

While Insperity has a public API, they only allow their customers to use it. Explore their Developer Portal to learn more.

How long does it take to integrate with Insperity?

If you use Finch’s unified API to access the employment data in Insperity (alongside over 200 other HRIS and payroll systems), it can take as little as a few days. See our quickstart guide for more information.

Where can I find developer documentation and support?

If you’re building a 1:1 integration using Insperity’s API, which is restricted to customers, the company’s Developer Portal is the best place to start. That’s where you can get answers to your frequently asked questions and access their API docs. 

If you’re integrating with Insperity via Finch’s unified API, navigate to our API docs. There, you’ll find a product demo, quickstart guide for developers, integration checklist, and product and developer guides, along with best practices to follow.

Of course, if you have any questions, we’d be happy to help answer them. Send your requests to

When does it make sense to leverage a unified employment API?

Unified employment APIs help developers access data from payroll and HRIS systems employers use. Specifically, these APIs are useful for accessing data from a broad range of employment systems or collecting detailed information about their customers’ payroll and benefits programs. If your use case requires integrations with three or more employment systems, a unified employment API could save you hundreds of engineering hours and developer resources. 

Through a single integration, you can connect with over 200 employment systems (including Insperity)—unlocking up to 88% of the employer market. Once authorized by the employer, you’ll receive fresh data every 24 hours. From enterprise-grade security to read and write capabilities, Finch offers compelling benefits to employer-facing businesses of all shapes and sizes. Visit our website to learn more.
