Quickbooks Integration with nuSOAP

I’ve been working on integrating an online shopping cart with in-house Quickbooks. I’m using SOAP (nuSOAP) and cURL / SSL to pass QBXML (Quickbooks XML) data through a port. Muchas gracias to Ryan Szrama of the open source project Ubercart for his extensive notes on Quickbooks / SOAP integration.I developed a pretty nice php class to pass data to the Quickbooks RDS server but the cURL requests kept failing, even though I opened the ports through the router and I had the computer they were passing data to on an FQDN DNS IP. It turns out I had to pass the IP through the server as well (SSH tunnel to: etc/hosts). It’s all good though, I would have liked to wrap up this project today, but it will have to wait for tomorrow.
