Let me route you in the right direction for assistance integrating your website to QuickBooks Online (QBO), b8831u.
While the QuickBooks Community can offer solutions and help with particular inquiries, there are certain aspects that only our Intuit Developers are equipped to address with specific details related to your issue.
We have a dedicated forum for engaging with other developers, product experts, and engineers on software, QuickBooks API issues, or developer license queries. Therefore, I recommend posting this question in our Intuit Developer Community, where they have the necessary tools and resources to help you with your concerns.
