Last week, OneNote launched the initial version of their API. The first set of features are focused on scenarios for creating pages in OneNote: mobile app scanners, hardware scanners, save-it-for-later for newsreaders, etc. The team has already started working on the next set of features. Here is a list of the capabilities and features that OneNote is planning to deliver over the next 3 to 6 months.

A OneNote API feedback site has been created to vote on features and submit ideas.
