Hi there, @AK112. I'll point you in the right direction to sort this out and fix program integration with QuickBooks Online (QBO).
We have a separate forum where developers, engineers, and other program specialists can interact and provide the details needed to address the error encountered with QuickBooks API and to fetch those specific items to have them available in another program. We'll write down the steps to help post your query:
