The Google Keep API is a RESTful API used to create apps allowing enterprise administrators to manage Google Keep notes, including creating, listing, deleting, downloading note attachments, and mutating permissions of a note. An example use case for the API would be to resolve issues identified by cloud access security broker (CASB) software. For example, if your CASB software identified a note with sensitive information, the Google Keep API could be used to restrict permissions on that note, or even delete the note.
