Insperity
Insperity is a professional employer organization (PEO) headquartered in Kingwood, Texas that provides human resources and business performance solutions to small and medium-sized businesses, including payroll processing, employee benefits, workers' compensation, HR compliance and the Insperity Premier HR technology platform. Insperity Premier exposes a REST Public API at https://api.insperity.com/public organized into four categories — Onboarding, Payroll & Tax, HRIS and Core — covering 45 publicly listed operations that let a client's applicant tracking system, HRIS or payroll application send new-hire records, submit employee change events, retrieve post-payroll general ledger data, and read the company-scoped reference code lists those writes must resolve against. Access is not self-service: a key is issued per customer by an Insperity Integration Specialist after an API Terms of Use Agreement is signed, requests must originate from allow-listed IP addresses, and the developer portal's Swagger documents require a Premier account.
Insperity publishes 4 APIs on the APIs.io network. Tagged areas include Fortune 1000, Human Resources, Payroll, Benefits, and HRIS.
Insperity’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, authentication, sandbox, and 14 more developer resources.
