Draft is writing tool boasting an array of features, but largely built around improved version control for collaborative writing. In Draft collaborators work on their own copies of a document, allowing the owner to accept or ignore individual changes.
The Draft API provides a RESTful interface for managing documents and collaborators. Supported calls include creating, updating, and deleting documents, comparing document versions, merging changes, managing manual savepoints, and much more. The API supports SSL, returns JSON formatted responses and authenticates using OAuth 2.
