Conversion assistance in an existing Quickbooks connected application. Our existing application uses the QB API to connect to a local copy Quickbooks 2013. We've updated QB to QB Online and need assistance in connecting to the Online API using OAuth from a stand alone Windows Form application. Progress has been made but there is something missing causing authentication errors. Look at the "[login to view URL]" file that shows the code we are using and the error message. After we can connect, we'll be able to complete the project or may opt to outsource the conversion.
