In the end I could, but not before Paypal attempted to convince me to couple my whole bank account with their systems, twice.

The second ‘attempt’/flow allowed me to enter my IBAN. I will change my original comment to reflect that.

I remember going through something like that with Plaid. That one actually asks for your online banking password, it's not using some API access... very bad.

I had to convince it that it didn't recognize my bank to eventually put in account numbers rather than give it credentials to your bank's online account. I think I put in the wrong routing numbers to get to that form. Definitely a bad experience!
