Quickbooks online sandbox using ODI

Hi all, Has anyone used ODI or any other tool/SOAP api to set up a direct connection to the quickbooks online API? Trying to use the developers sandbox to test connections and cardinality. Intuit's documentation is too outdated and no clear way to use any jdbc or any api directly to set up connection. People at Intuit kindly add documentations on your developers website. Although you use qodbc as a primary language which keeps it secure, it becomes unnecessarily hard for developing other apps or extracting data on the backend!
