OpenZaak is a production-ready API platform that implements the Dutch national standard for case-oriented working (also known as the ZGW-API’s). OpenZaak makes it possible for municipalities to offer safe and reliable online services to its citizens. Because OpenZaak relies on the case-oriented working standard, it becomes easier to securely exchange data with other municipalities and / or applications. OpenZaak is open source software. This means that everyone is free to reuse this software or adapt it to their needs.

Cases, Decisions, Documents and Open Notifications

OpenZaak implements the ZGW-API’s and combines them with a user-friendly management interface. By using the open notifications standard, updates on citizens cases can be published to different systems. In this way, every system is automatically informed about the status of a case.

Catalog & municipal selection lists

OpenZaak includes a management interface for catalogs and municipal selection lists. For example, you can use standard selection lists when implementing your business process and adjust or supplement them where necessary.

API Dashboard

OpenZaak includes an API dashboard that provides insight into the use of OpenZaak. This will give you a better insight into the usage of OpenZaak. This can help adjust and prioritize the handling of cases.
