I'm developing an Java web application in which users have an opportunity to see and download their transactions. I would like to have a feature to download transaction into QuickBooks. I know that I can import transactions into .OFX format, but I'm wondering if it is possible to download transactions into QuickBooks Online via QuickBooks API? Any suggestions? Examples are appreciated.
I have took a look on the API and I have seen customers, invoices, payment and other things that can be done using API, but I haven't seen nothing about transactions.
And one more question. In which way do the QuickBooks adds financial institution and how is it possible to be QuickBooks supported financial institution? Thank you.
