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 ADP?

As of 2021, ADP was the human capital management (HCM) market leader with 10.8% global market share, according to 

The company currently boasts over 1 million customers worldwide, though it’s unknown how many of those reside in the United States.

How can I access the employment data in ADP?

To access your customers’ employment data in ADP Workforce Now, you have two options: 

  1. Build custom 1:1 integrations with ADP’s robust library of APIs, which enables automatic data sharing between your app and ADP Workforce Now. 
  2. Build a single integration with Finch to access the employment data housed in ADP plus more than 200 other employment systems.

Does ADP Workforce Now have a public API?

ADP offers a robust library of APIs to customers and approved partners. While it’s possible to access the data housed in ADP Workforce Now through the company’s APIs, you must first apply to become an ADP Marketplace partner—making it a gated API. 

Keep in mind that to become an official partner, you may be required to invest resources into business development efforts. You can find more information on ADP’s Marketplace homepage.

How long does it take to integrate with ADP WFN?

That largely depends on the integration method you choose. 

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

If you instead decide to build a 1:1 integration leveraging ADP’s library of APIs, it can take months to receive your production keys. See ADP’s developer resources for more information. 

Where can I find developer documentation and support?

Since day one, security and transparency have always been priorities at Finch. We are committed to protecting the data of our customers, employers, and employees.

If you’re building a 1:1 integration using ADP’s library of APIs, the company’s Developer Resources page 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 ADP Workforce Now 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 plans. 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 ADP Workforce Now)—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. Learn more
