FinTS Dummy Server for Testing SEPA Flows

[leobeal]

Hi everyone,

After once again making a change to my SEPA flow and being scared to deploy since I could not test it properly, I decided to vibe-code a FinTS server. Feel free to use and test it.

Instructions

Available at:
https://plannino.com/

FinTS endpoint

https://plannino.com/fints

Error simulation

Some errors can be simulated via query parameters, for example:

https://plannino.com/fints?error=limit

Future

I honestly don't know how much this will be maintained, if I will open-source it, or even if it will become a small paid product.
It's already serving 95% of my needs. It still does not return TAN media properly, but I want to work on it. (It works correctly if you send any TAN medium, though.)
That being said, use it as much as you want, but please don't use this in any critical automated workflow.

Security

I DO NOT store any logs. Still, you SHOULD NOT pass real bank credentials to these APIs. The instructions provide usernames and PINs that can be used for testing.
