The Unified API for HR and Payroll

Integrate with 200+ HR and payroll systems through a single, unified API. Finch handles complexity behind the scenes, reducing build time and maintenance.

One data model to unite every provider

There are thousands of HR and payroll systems on the market for employers. Our API connects these data providers through a single data model.

Standardized Data

Each provider labels and stores employment data differently. We standardize all data that's returned so you don't have to.

Automatic Typing and Classification

Our API interprets and classifies data into clear, consistent types for earnings, taxes, contributions, and deductions.

Custom Fields

Use custom fields to access supplementary data stored on employee profiles, like t-shirt size, drivers license number, and more.

Request Forwarding

For any data not included in our data model, make a direct call to the underlying provider. Finch acts as your secure authentication layer.

Built for the employment ecosystem

Onboard organizations, track payrolls, and manage deductions through a single API. Our products help you read and write employment data seamlessly.

“Finch is the best solution in its category.”

Payroll integration shouldn’t be your core competency. Like Stripe for payments and Plaid for bank accounts, Finch is the best solution in its category. It would take you longer and cost you more to reinvent the wheel.
