+If you have an admin token with appropriate permissions, you can make API calls in the context of a managed user. In order to do this you must request Box.com to activate As-User functionality for your API key (see developer site for instructions). 
+```c#
+var config = new BoxConfig(<Client_Id>, <Client_Secret>, <Redirect_Uri);
+var auth = new OAuthSession(<Your_Access_Token>, <Your_Refresh_Token>, 3600, "bearer");
