Trusted by leading TA tech companies
Why leading Talent Acquisition Software 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 ATS. Reading jobs, candidates, and applications and writing back new applications, stage changes, and attachments works the same whether you're connected to Greenhouse, Ashby, Oracle RC, or SmartRecruiters - same endpoints, same fields, same format.
Same granularity as a direct integration
Our unified API is built to cover all 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.
Optimized syncing for ATS instances with millions of candidates
Candidate packages sync large ATS instances one candidate at a time. Kombo first indexes every candidate, then fetches each one with its applications, interviews, notes and scorecards, starting with the newest and most recently updated. Your AI screening can score this week's applicants while years of history fill in behind them. If a sync stops, the next one picks up where it left off.
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.
Transform values into the shape your product expects
Advanced mapping transforms a value before it lands in your custom field. Combine a job's description, benefits and qualifications into one posting-ready text, or turn a location spelled ten different ways into codes your search filters can rely on. You build it in the dashboard against a real record, preview the output and save. Changing a mapping needs no release on your side.
