Hi Arun,
Its an interesting question, thanks for posting it on the community!
I was going through the box.com site and see they have some cool RESTFUL APIs setup for integrating with the platform.
You can do a simple callout from the Apigee Platform to call the box.com APIs. Again I havent tried it but dont see it be any different from other REST based platforms/backends.
Have fun building some cool Apps!
