Check Components is one of 4 APIs that [Check](https://apis.io/providers/check-hq/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include React, Embedded UI, Onboarding, Components, and Run Payroll. The published artifact set on APIs.io includes API documentation, a getting-started guide, and an API reference.

Check Components is a library of white-labeled, drop-in React UI elements that handle the highest-friction surfaces of embedded payroll — company onboarding, terms of service, bank linking, employee tax setup, withholdings (W-4), filing authorization, verification documents, and Run Payroll — including the Check Onboard flow. Components are embedded via short-lived component links generated through the API and emit DOM events for lifecycle states.
