Welcome to the QuickBooks Community, tzisopoulos!
We have a different Community for app developers. I'd suggest posting your question in there. You can follow this link: https://help.developer.intuit.com/s/. Then, to post a question, you can click the Questions header beside TOPICS and click the ASK A QUESTION button.
Here, we answer questions about QuickBooks, but not at a developer level.
If you need anything else, please don't hesitate to go back to this thread.
