Thanks @Rubielyn_J for your response I really appreciate it.
But if I have to get Account type list from our Application then which query I have to execute for that.
For example : To get list of Chart of Accounts I execute "select * from Account" query so, If I have to get list of Account Type then query I have to use?
The information sent to QuickBooks Online (QBO) depends on what your third-party application shares with us. I'd recommend contacting their support on what Account Type you'll need to use to match with it in QBO. Here's an article you can refer to about using account types and detail types in your chart of accounts.
Once done with importing the transactions and when you're ready to reconcile your accounts to keep your QuickBooks accounts accurate. follow the steps below:
Go to the Gear icon in the upper-right.
Click Reconcile under Tools.
Select the correct account and add the following information that's shown in your bank statement.
