Thank you for your interest in integrating a third-party app to your QBO company. However, I'm unable to check the app you mentioned using only acronym information. Can you please comment the full name of the app so I can find it for you? You can also try finding it on the Apps Store page for QBO Global.
On the other hand, if you're creating an app for QBO, you'll want to repost your question to the Intuit Developers Community. They are more than capable of answering questions about developing a system to integrate with QuickBooks. Here, our expertise is more about customer service support and not about app development.
