O365 Graph to pull Calendar, mail, contacts and more (reminders, birthdays, tomorrows first meeting :))

Hi All,
I’m learning as fast as I can but sadly i’m not well versed in JSON or REST - if someone fancies having a crack at creating a smartapp that can authenticate to Office 365 and then parse the JSON response? Ideally i’d love to have this integrate with WebCoRE :wink:

[on the left show more samples and enable calendar and many more]

Or if anyone can share a good REST resource to learn how to structure the authorize, token and actual query that would be great!
