2020 U.S. Election API Resource Center

During this election season, citizens and officials at all levels need quick, easy access to real-time data from a wide range of sources. This type of information exchange is what APIs do best, and as an API-first company, Postman is committed to providing whatever assistance we can in this area. This resource center is a toolbox of API collections, visualizations, and tooling to help you make sense of the 2020 U.S. election.

Featured API Collections

U.S. Census Bureau

In alignment with the Digital Government Strategy, the Census Bureau is offering the public wider access to key U.S. statistics. The Census application programming interface (API) lets developers create custom apps to reach new users and makes key demographic, socio-economic and housing statistics more accessible than ever before. The Census Bureau’s API allows developers to design web and mobile apps to explore or learn more about America's changing population and economy.
