Gusto Embedded Payroll API
The Gusto Embedded Payroll API enables platforms to build and embed modern payroll, benefits, and HR tooling into their own products. The API exposes endpoints for company onboarding, employee and contractor management, payroll runs, tax filings, benefits administration, ACH transactions, and compliance reporting. Authentication uses OAuth 2.0; partners must complete commercial, security, and implementation reviews with Gusto's partnerships team before moving from the demo environment to production.
