I would like to put all bunq bank transactions in real time in an Excel file. The free version of Zapier is insufficient, the paid version is quite expensive. That is why I now run n8n (free and open source automation software) on my own server. The idea of ​​keeping my own data on my own server also appeals to me very much!

Unfortunately, I am unable to set up the connection with n8n via Oauth2.

First of all, I am unable to log in to the developer portal to create an app. (I've tried multiple browsers including Firefox and Chrome, and multiple laptops on different networks.) When I enter my code, I get an error message that additional information would be required. Was anyone else able to solve this issue? I've contacted Bunq, but no response so far..

Despite the error message, I can still retrieve a user ID and secret in the Bunq app on my phone. I have tried to set up a connection in n8n with this, see all other screenshots. Unfortunately, I get an error message as shown below.

Has anyone else succeeded? I would really appreciate it if you could share a step-by-step plan for this!

If anyone knows of another way to get the transactions into Excel in real time (preferably for free), I'd love to hear about it too!

Thanks!
