I know that banks in Europe are bound by law to follow PSD2, which is a set of guidelines to propose APIs. I found a stackoverflow post to generate the required certificates for that but those are only supposed to be for testing purposes stackoverflow.com/…/how-to-create-eidas-certifica…

You can use the PSD2 api to fetch the transactions from your account directly, that would be a lot less troublesome. There is also the woob (formerly weboob) project that has web scraping for a lot of banks (specifically french but also some American ones like amex)
