City of Chicago 311 API MASTER RECORD


The City of Chicago 311 API allows developers to make requests directly to 311. When citizens contact 311, they can get information of animals, consumer and employee protection, disability, garbage and recycling, health, home and buildings, parks, trees, and environment, public safety, seniors, and transportation and streets.

Developers can authenticate with an API Key and use two different endpoints, one for testing, and one for production. GET methods enable requests to the city database.

By calling 311, residents can request city services, report non-emergency issues, and get updates on city work. Use this API for a city service, study the app that the City of Chicago provides, and contact the director of analytics, Tom Schenk Jr for additional information@tomschenkjr
