I'm sure someone has done this before and I'm just not searching correctly to find the answer, but I have an application that allows people to provide links to files they have shared via box. My application needs to authenticate against Box as a user within the company to validate that the link the person has provided has been shared correctly such that people within the company have access to it. There must be a way to perform the necessary auth and attempt to access the shared url to validate that company users can access the file. Oh, and did I mention my company uses Enterprise SSO to access Box? Any guidance and/or sample code would be greatly appreciated.
