We are using payment api for fetching payment information. But when I deleted a payment from QBO than api will not going to provide any details regarding deleted payment

Thanks for reaching out to us through the QuickBooks Community, @vipul-exactitsol.

We want to make sure you're able to log your payment properly in QuickBooks. While QuickBooks is only a receiver of the info from your API, you still need to work with them with the modifications made to your payments.

We can only help you record your payment manually, in case they will not forward it again. Here's how to record payment for a single invoice:

1. Select + New.
2. Click on Receive payment.
3. From the Customer dropdown, select the name of the customer.
4. From the Payment method dropdown, select the payment method.
5. From the Deposit to dropdown, select the account you put the payment into. Tip: You can put the money directly into an account, like your checking account, or select Undeposited Funds if you need to group the payment with others. 
6. In the Outstanding Transactions section, select the checkbox for the invoice you're recording the payment for.
7. Enter the Reference no. and Memo if needed. This is optional.
8. When you're done, select Save and close.

To clear the confusion, I want to tell one thing:

We are accepting payment in QBO and after that we read payment from QBO and record it in other personnel server. That flow working fine.

But the main issue comes after that, Suppose someone delete the payment from QBO, In payment api we don't get any update or able to read deleted payment information.

Any idea or suggestion will be helpful.

Great, Thanks
