# Introduction

> Learn how you can put integrations on autopilot through Kombo’s unified APIs.

Welcome to the Kombo docs! You’ve come to the right place to learn more about how Kombo can help you build integrations faster and more reliably.

### **What is Kombo?**

Kombo offers unified APIs for HR Tech. We allow our customers to build a single integration to Kombo and instantly launch all the HRIS and ATS integrations in **[Kombo’s ever-growing portfolio](https://www.kombo.dev/categories/all)** to their customers.

We do this by standardizing the data models exposed by the integrations we support and allowing you to interact with the unified models using a set of clearly defined endpoints.

This way, reading employees from an enterprise HR solution like **[SAP SuccessFactors](https://www.kombo.dev/integrations/successfactors)** will look the same as reading employees from a more SMB-focused tool like **[Personio](https://www.kombo.dev/integrations/personio)**. It’s the same set of data models and fields you can rely on.

### Unified APIs

When building multiple integrations for different tools, the effort and time spent both to build and maintain these integrations can quickly rack up. With Kombo, you don’t have to worry about the complexity of the tool; you’ll receive data in the same format for every tool you choose to support.

We offer a separate unified interface per software category. Click on one of the buttons below to learn more about the data models and write-actions we provide per category.
