Gingko is a personal information management system that incorporates "card-trees," a kind of document that's part outliner, part mindmap. The web interface is a tree structure of cards, used for note-taking, productivity systems, writing, and/or group collaboration. The API documentation, outlined using Gingko's own information management system, lists the possible API GET and POST calls that enable a user to programmatically obtain user cards and information, create and modify existing cards, create new card trees, and trigger events manually. The Gingko API works with JSON formatted requests and responses.
