KVK Developers Portal

Reliable business data, straight from the source, automatically integrated into your systems.

How does it work?

Add current data from the Business Register to your own systems with our APIs. An API (Application Programming Interface) enables two systems to communicate with each other. Data from the KVK is automatically retrieved and integrated into your systems. You do not need to configure anything manually. This prevents errors and ensures that data remains consistent across all systems. 

Try our APIs for free! No implementation or registration required. With a small set of fictitious data, you run various test scenarios.
