Issue reporting / Open311API

Empowering Citizens

The Issue reporting API / Open311 API enables sending service requests to the city’s feedback system. It can be used to report for example broken street signs, potholes, etc. It can be used for reporting on other issues as well.

The issue reporting API is based on GeoReporting version 2, which is better known as Open311. The interface is designed in such a way that any GeoReporting version 2 compatible client is able to use the interface.
