Merge HRIS & Payroll API
Unified API aggregating 80+ HR and payroll systems (ADP, Workday, Gusto, BambooHR) into a single normalized integration layer for agent-driven workflows
Viable option — review the tradeoffs
You need to pull employee data, payroll runs, and benefits from 80+ disparate HRIS systems like ADP, Workday, and Gusto without building and maintaining separate integrations for each.
Days to integrate vs quarters; fresh API-based data with auto issue detection; rate limits 100-600/min per account; sync frequency up to automatic but varies by provider; full coverage not universal per integration.
Your agent workflows require real-time HR data syncing for onboarding, payroll automation, or compliance checks across customer HR stacks.
Reliable for leaders like Ramp/Drata; historical employment tracking where supported; quirks include per-integration feature gaps (check coverage matrix) and sync credits for manual resyncs.
Per-Integration Feature Gaps
Not every HRIS supports all models (e.g., deleted data, third-party webhooks); sync every 3 days standard, premium for faster; check supported features matrix.
Rate Limits Per Linked Account
100-600 requests/min per customer account (Launch/Pro/Ent); bursts ok but sustained high volume hits limits—monitor via dashboard and use modified_after polling to optimize.
