Unified API for HR, ATS and payroll system integrations.

kombo.dev ↗

Kombo expands its unified HR API into Payroll data models, opening a new data category for integration builders.

◆Current state
Kombo is a unified HR integration API shipping on a weekly changelog cadence, covering ATS, HRIS, LMS, and — as of August 30 — Payroll data models. Recent releases have a dual rhythm: graduating integrations from beta to General Availability in bulk while simultaneously adding new ones (Atlas, Skello, Zellis, Talent360). Integration depth is also growing, with Workday performance overhauls, Lever high-performance sync modes, and Greenhouse scorecard sync all landing in August.
◆Where it's heading
The product is expanding its data model surface area (Payroll is the newest) while tightening the reliability of existing connections. AI-assisted formula generation for custom field mapping reduces the configuration burden for complex data transformations. The trajectory is toward a comprehensive HR data fabric that covers the full employment data stack rather than just ATS/HRIS connectors.
◆Prediction
Payroll data model launch typically precedes specific payroll integrations — expect Gusto, ADP, or Paychex connectors in the next 30-60 days. Advanced Mappings AI assistance will likely expand to more formula types and field contexts as adoption grows.

    ATS API Updates - September 6, 2026

    Atlas launches as a new ATS integration in Open Beta, Spott gets webhook support for real-time events, and both Bullhorn and Teamtailor gain candidate notes. Three distinct integration expansions in a single weekly release, consistent with Kombo's pattern of shipping integration breadth and depth simultaneously.

    HRIS API Updates - September 6, 2026

    HR4YOU and SD Worx get full absence management coverage, Workday gains support for future-dated terminations, and live data previews for custom field mapping expand significantly. Each deepens integration fidelity for specific HRIS customers rather than adding net-new surface area.

    Kombo launches Payroll data models, adds Skello and Zellis integrations

    ⚡ SPARK

    New Payroll data models launch alongside two new integrations (Skello, Zellis) and major Workday performance upgrades, with many integrations graduating to GA. The Payroll data models expand Kombo's API surface into a new data category — previously it covered ATS, HRIS, LMS, and Assessment, but payroll data has different compliance and data access requirements that Kombo is now formalizing.

    ATS API Updates - August 30, 2026

    Multiple ATS integrations graduate to General Availability, Emply People gains create-candidate support, Greenhouse gets scorecard sync, and Lever gets a new high-performance sync mode for large datasets. The GA graduations signal that Kombo's integration quality bar has standardized — moving betas to production-ready en masse.

    Platform: AI formula assist, Candidate Sync page, webhook performance

    AI-assisted formula generation for Advanced Mappings reduces the TypeScript expertise required to transform custom field data, the Candidate Sync page gives customers visibility into their ATS sync state, and webhook performance improvements harden real-time event delivery. The AI formula assist is the most notable: it extends the Advanced Mappings feature launched the prior week to non-technical users.
