I came to you site via suggesting from the Program GNUCash (gnucash . org) after trying to set details
from dialogues.

The account I was trying to setup,
Ulster Bank Ltd Ireland, 'allows' the export of OFX data manually at accounts
from:
https://www.ulsterbankanytimebanking.ie

The Database Fields on your website for entering new data, give no guidance
as to what they meant, or where to find such information.

Also the bank in question also gives no guidance for using another verifiable access interface.

Where do I go from here ?

Thanks
