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 QuickBooks Payroll?

Given that QuickBooks Payroll boasts over 1,400,000 customers, and there were 6.1 million employers in the United States as of 2019, QuickBooks Payroll is estimated to serve 22.95% of the U.S. market.

How can I access the employment data in QuickBooks Payroll?

To access your customers’ employment data in QuickBooks Payroll, you have two options: 

(1) Build a custom 1:1 integration with QuickBooks Payroll via its public API, which enables automatic data sharing between two apps. 

(2) Build a single integration with Finch to access the employment data housed in QuickBooks Payroll plus over 200 other employment systems.

Does QuickBooks Payroll have a public API?

QuickBooks Payroll offers the following APIs and SDKs:

  • QuickBooks Online API
  • QuickBooks Payments API
  • QuickBooks Desktop API
  • QuickBooks Time API
  • QuickBooks Lacerte SDK

You can learn more about Intuit’s APIs and SDKs on the company’s Developer Portal

Note that all Intuit APIs and SDKs are gated, meaning you must become an approved partner before you can access production credentials—something that may involve mutual business development efforts. Each year, you must also undergo a comprehensive security assessment. 

How long does it take to build QuickBooks Payroll integration?

That largely depends on the integration method you choose. 

If you use Finch’s unified API to access the employment data in QuickBooks Payroll (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 one of QuickBooks Payroll’s APIs or SDKs, it can take up to two months to receive your production keys. See QuickBooks Payroll’s notes on how to publish your app for more information. 

Where can I find developer documentation and support?

If you’re building a 1:1 integration using QuickBooks Payroll’s external API, the company’s Developer Portal is the best place to start. That’s where you can view Intuit’s API docs, learn about their requirements, and apply for production keys. 

If you’re integrating with QuickBooks Payroll 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 QuickBooks Payroll)—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
