Like the Capitol One Topic, I also couldn't get OFXget to work. I did get it to return "Dicsover Card" by entering Discover in the search field, After selecting Discover Card a new screen appeared.
Entering account and password and clicking 'download' resulted in an
Server returned HTTP response code: 400 for URL: https://ofx.discovercard.com
The data field remained empty.
Google for 'HTTP response code 400' finds a page with
HTTP Status Code - 400 Bad Request. The request could not be understood by the server due to malformed syntax.
Any advice or help would be appreciated.
