Because these API are not meant to be public for the end user to use.

Access to that kind of data requires regulation, a lot of it and that's why Third Party Providers exist. There are a lot of them in Europe and they're not expensive.

I actually didn't expect to find anything about bunq around here but I have to say they're the worst bank I've worked with. When we started working with them, their API were broken and the devs had no idea why. It seems to have improved recently but it's definitely not a bank to praise for their API.

Bunq… It’s great that they have an API, but to use it, I had to clone their SDK, and manually fix everything that was broken, add some workarounds, and now it works. Documentation was all from the announcement in 2016, me using it was ~2022, and some undocumented things changed since. Still, better than no API, which is what everyone else seems to offer.

And now we have a paypal-like shopping experience via SEPA Instant Payments, all our PayPal hating customers are happy ;)

I know, that's my point. It's a stupid decision.

> Access to that kind of data requires regulation

It's my data. I want to access it how I see fit.

I already have a bank and I already pay them. I don't want to pay anyone else to be able to use my bank account in a way that suits me. Sadly, there aren't many good options.

Someone mentioned Wise, and they do seem pretty interesting. But it makes no sense why common high strees banks refuse to cater to power users, or even to users who aren't using mainstream devices.

It ain't your data, it's the bank's data about you. Banks are shitty about access, APIs because they are perpetually in CYA mode from KYC/AML rules from the US (also on most foreign banks) and GDPR and cousins in Europe.

I was actually surprised how many bank apps will work under GrapheneOS even if only partially.

"Power users" don't make them more money. In fact, from their POV, you're a legal, reputational, and security liability.

reply
Reputational and security liability is highly debatable. Legal is highly jurisdiction dependant.

They often act as marketing and can find and report security vulnerabilities rather than the criminal element doing so first.

> Reputational and security liability is highly debatable

Hmmm then why are banks telling people to not use AI systems to log into their bank?

Whilst not PSD2/PSD3, I've been super happy with Wise; an excellent API, good quality docs. A _proper_ test environment that you can drive using hooks they expose. Nothing but praise for them, including their support, which has helped me around the clock even on weird questions such as why my custom integration fails to send a transaction (mismatched currency between recipient and transfer in my code).

Not going to be a good day when Wise or Plaid are breached and accounts start being drained. Adding middlemen is not a solution to poor banking services.
reply
Wise is not a bank, is not licensed as a bank, and is thus not insured like a bank is.

Balances are held in Wise at your own risk.

In Hungary you don't get documentation for these APIs only in pdfs via email, and if you get it the APIs are not stable, constantly breaking. I was always dreaming about creating an automated testing suite and report all of the issues automatically to the national bank, which is the supervisor of all commercial banks in HU, in a hope to punish them.
reply
You guys get APIs??

Seriously, count your blessings man. In America we only get Plaid, which only works right or reliably for big banks (which are also the worst ones), and it isn’t an API for humans, just a paid SaaS product that a company who wants to offer integration with banks has to pay (i assume a lot) for.

> "Open banking" is kind of a thing with PSD2/PSD3, but in name only. In reality, it's impossible to build anything useful

You mean the step from sandbox to production application, or you're not even getting access to the sandbox itself? I managed to get sandbox access with ease via two separate banks (both Spanish though), with no problems, think it took them one (working) day or something to review my "application". I never tried to get anything into the production environments though, but makes sense they'd be a bit tighter on that tbh.

Not sure why you'd claim it's impossible, it's in wide use already by banks, fintech and payment service providers across the union.

reply
I should have added that it's impossible for individuals, not for fintech providers.
reply
I guess I should have clarified too, I'm an individual, not a fintech provider.
