Hi there, @jecalderon,

We have another forum called Intuit Developers. There is where you can find help with establishing a connection between your third-party website or applications with QuickBooks Point of Sale. You can interact with users, engineers, programmers, and developers who are willing to share their insights and best practices with your concern.
