Why leading HR Tech players choose Kombo
One standardized model
Read and write data across every supported system using the same set of endpoints. Whatever system your customer is on, 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, then transform the values in the dashboard when the source format doesn't match what your product expects.
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 or payroll system. 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 HRIS or payroll data to your schema. Call the underlying API directly with passthrough for edge cases. All in real-time if needed.
Transform values into the shape your product expects
Advanced mapping transforms a value before it lands in your custom field - calculate an FTE from weekly contract hours, or reach into a nested Workday response for a field the unified model doesn't carry. You build it in the dashboard against a real record, preview the output, and save. Changing a mapping needs no release on your side.
Spot broken syncs before your customer does
Kombo shows sync status, authentication issues, and errors across every customer connection in our dashboard, with searchable logs for every API request. Webhooks fire when a sync fails or a credential needs attention, so support can handle most of it without pulling in engineering.
See what a customer's data actually looks like
The Data Explorer lets you search everything Kombo has synced - employees, absences, groups, legal entities, and the relations between them. Every write action the API supports runs from the same UI, so you can write against a sandbox and watch how a system handles it before you run it in production.
