Hello, zodgevaibhav.

Thanks for getting back to us! I'll point us to right direction to help us fix the API for the Banking feature. 

We may need to do some tweaking on the API tools for the rules to work with it. The same can be said for the flag that tells the transaction to go to the For review section. 

It would be best to post these questions in our Intuit Developers Community page. The dedicated support agents and fellow programmers would be able to provide more details and ideas about how to resolve the API issues for the Banking feature. 

We can post the questions here: Intuit Developer Help page for QuickBooks Online. 

Aside from the tools you've mentioned, I'll also share this document in case you need help with the functions in the future: https://developer.intuit.com/app/developer/qbo/docs/get-started.

After getting all of the transactions in, I'm sure you'll also need to review how they affect your overall financials. We can run reports to do this, and if you need help with it, I'll share this article with you: Run reports in QuickBooks Online.

You can always drop by if you have questions about managing your transactions in QuickBooks Online. Aside from that, do you also need help with certain reports or entries? Let me know and I'll help you out.
