There are two folders in the ZIP. 

VitriumClasses folder defines classes used by Vitrium APIs, and HttpClient folder defines the client functionality for calling the APIs. 

The piece you will most interested in is HttpClient/VitriumClient.php – everything else is there to support the functionality of this class. 

It has several methods already implemented: 

	login() will perform the login challenge/response handshake; 
	
	getOrCreateFolder() retrieves a folder by name if it exists or creates it if it doesn’t; 
	
	getContentSettingIdByName() looks for a content setting by name and returns its ID; 
	
	protectContent() uploads a file. 
	
Some of these may be applicable to you project and others may be irrelevant but all show the process of calling our APIs and can be modified to suit your needs.
