Let me route you to the best support available who can verify if limiting the APIs in pulling up data from QBO is possible.
We have a separate online forum called Intuit Developer Community where you can post system development type of questions.
I'd suggest contacting our Intuit Developer's team through this link: https://developer.intuit.com/. From there, one of our developers will answer your inquiry and be able to receive clarification regarding the matter.
Please let me know if there's anything else I can help you with. I'm always here to further assist.
