Sage 50 Quantum Accounting ODBC or API

[Corry]

In the past I wrote an interface that interacted with Sage Businessworks.  It was a file based data exchange.

Is there a method to interact via ODBC or another type of API for Sage 50 Quantum Accounting?

I have a new customer for the software I created that is using this accounting package and need to know where to start finding information to exchange customer data and create invoices from my system to this one.

Any guidance would be great.
