Trusted by the world’s leading B2B companies

Why leading HR Tech players choose Kombo

One standardized model
Read and write data across any HRIS using the same set of endpoints. Whether it's Workday, SAP SuccessFactors, or UKG Pro, you work with the same data model.
Seamless authentication
Embed our white-labeled connection guide into your product to easily let your customers connect their systems.
Access any data
Map custom fields from any system to your own unified schema. Use remote data to access raw data when you need to access niche fields.
Full visibility
Track sync status, spot authentication issues, and debug problems from the dashboard. Get webhook notifications when things change or need attention.

One data model for every integration

Build to Kombo once and connect to any HRIS. Reading employees, employments, and absences and writing back time off requests, documents, and employee updates works the same whether you're connected to Paycor, Oracle HCM, Personio or BambooHR - same endpoints, same fields, same format.

Same granularity as a direct integration

Our unified API covers most use cases, but every system has its quirks. Use custom fields to map tool-specific data to your schema. Access raw data from the source with remote data. Call the underlying API directly with passthrough for edge cases. All in real-time if needed.

Monitor all your integrations from one place

See sync status, authentication issues, and errors across every customer connection in the dashboard. Searchable logs show you exactly what happened with each API request. Set up webhooks to get notified when errors occur or credentials need attention, so your support team can resolve issues without always having to pull in engineering.
