I am using Dwolla’s IAV flow.
It works when I use my login credentials for some banks e.g. Alaska USA Federal Credit Union but doesn’t work when I use my login credentials for other banks e.g. KeyBank, Novo.
I’ve verified by going to the respective bank websites that the login credentials are correct, but I still see the error message:
“Please make sure your login or security information is correct.”
Is there any restriction when using the IAV flow? and is there a way to get another error message for our users?
