Factorial
Factorial is an all-in-one HR, payroll, time, talent, finance, and IT management platform headquartered in Barcelona, Spain, used by 16,000+ companies worldwide. The Factorial public API is a date-versioned REST API (current major 2026-04-01 "Legendre") covering employees, contracts, attendance, time off, payroll, ATS, performance, trainings, projects, finance, banking, procurement, IT assets, documents, webhooks, and an Approvals workflow surface. Authentication uses OAuth2 (on behalf of a user) or an x-api-key header (on behalf of the company), with 30+ scopes for granular partner access. Factorial publishes the OpenAPI schema and generated SDKs (Ruby, Python, Java, PHP, TypeScript, Node.js) at github.com/factorialco/oas and exposes an llms.txt index for AI agents.
