NationBuilder is an open platform for users to create online communities centered around issues relevant to them. Users can create community organization websites, access a people database, and use communication tools such as email, text messaging and social media.
The NationBuilder Election Center API uses REST calls and returns JSON. The service offers access to a database of voter data, political and geographic regions, and other campaign information. This data can be integrated into third party applications to facilitate the design of campaign centered applications.
