I've been researching this for a while, and I really can't find the right solution. I found this PHP API that is supposed to help solve all these issues, but it doesn't work - or it's not clear how to set it up correctly. 

This is the PHP api I've tried to use

* Updated quick-start guide: <http://www.consolibyte.com/docs/index.php/PHP_DevKit_for_QuickBooks_-_Intuit_Partner_Platform_Quick-Start>

I was able to get OAUTH to connect on the ipp developer site, so that's nice. But I can't get any data.

I'm just trying to automate some processes for my company with our quickbooks - online store integration.

Basically I just don't understand what to do to get say a list of POs from quickbooks online. Could anyone shed some light on this?

Thanks!
