**Website:** https://www.salsa.dev/  
**APIs profiled:** 8

Salsa is embedded payroll infrastructure that lets SaaS platforms add native, multi-country (US and Canada) payroll to their products through REST and GraphQL APIs, embeddable UI components (Salsa Express), and real-time webhooks. Partner platforms provision employers and workers, run payroll, disburse worker payments, and handle tax setup and filings without leaving their own app. API access is partner-gated - Salsa issues sandbox and production Bearer API keys to approved platform partners.
