thank you for the response @Maybelle_S 

I should have clarified that we are using the Payments API and we can't find a way to know when a charge is being disputed. there is no way to be notified, or any change in the information coming about the transaction in the API. the balance won't change and QBO API is not providing a transaction status (which is a whole issue on its own). How do we, the developers of businesses who build our products' finances directly into QBO via the API can be notified of disputes? 

Today we relay on the Balance section of the JSON, which is entirely inadequate and lacking ion accuracy. With credit card transactions the balance updates to 0 and stays that way even when later the transaction status changes. In ACH the Balance is showing 0 (Paid) before the money is leaving the payer's bank and before the time that the payer can cancel that transaction.

You have a lot to learn from Stripe and we are seriously considering changing our merchant provider because of QBO's lack of attention to the intricacies of managing a healthy balance sheet.
