CSB API Documentation

Citizen Service Bureau API methods, using the Open311 spec


The Citizens' Service Bureau (CSB) is the customer service department for the City of St. Louis. This API provides access to some of the data collected when services are requested.

Please request an API key to use this API.


This API uses the Open311 GeoReport v2 specs, with the exception of the POST method. 

This means that applications are unable to post requests to our database, just pull information out. 

See the Open311 GeoReport v2 wiki page for details on each method.
