Check Payroll API 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 Payroll, REST, Webhook, Tax Filing, and Money Movement. The published artifact set on APIs.io includes API documentation, a getting-started guide, an API reference, authentication docs, and rate-limit docs.

The Check Payroll API is a comprehensive REST API for embedding end-to-end U.S. payroll inside another platform. It models companies, workplaces, employees, contractors, pay schedules, paydays, payroll cycles, payroll items, earnings (regular, overtime, tipped, piece rate, reimbursements), post-tax deductions and garnishments, benefits (pre-tax and post-tax), net pay splits, paystubs, paper checks, money movement, tax parameters and elections, tax deposits, tax filings, employee tax statements (W-2 / W-2C / 1099), tax packages, fulfillments, setup and embedded setup, integration partners, webhook configs, communications, and notifications. All resources are accessed under a versioned, bearer-authenticated REST surface with idempotent writes, bulk operations, pagination, and sandbox simulation endpoints for funding and disbursement.
