Folkesparekassen API Access & Open Banking Data

Folkesparekassen is a Silkeborg-based ethical cooperative bank (andelskasse) whose customers increasingly want their account data in their own tools — budgeting apps, spreadsheets, or bespoke scripts. open-banking.io gives you that reach without certificates, sandbox paperwork, or a bank developer programme. It is a zero-knowledge service covering 2,600+ EU and UK banks, where every figure is decrypted on your own device with a key nobody else holds — not even open-banking.io.

Both business and personal Folkesparekassen accounts are supported. Access is granted under PSD2 for up to 180 days per consent before you re-approve, and no BIC is required to set the connection up.

How to connect Folkesparekassen

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key involved in this step.

  1. Sign up for open-banking.io and set an encryption passphrase. Your keys are generated locally on your device, so the passphrase never leaves your machine.
  2. In the dashboard, search for Folkesparekassen and choose the account type you need (business or personal).
  3. You are redirected to Folkesparekassen's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Once you confirm, your accounts sync back into your dashboard, ready to view or export.

Because you authorise directly with Folkesparekassen, your credentials are only ever entered on the bank's site.

Access your data

Programmatic access is an optional step after the connection exists. On the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. From there you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly.

Every request sends the X-Api-Key header, and every response is decrypted locally with your own key. An API key on its own only ever returns ciphertext — without your private key, no one (including open-banking.io's servers, which hold only your public key) can read a single balance.

All of this runs for around EUR 3/month.

FAQ

Do I need a BIC to connect Folkesparekassen?

No. No BIC is required — pick Folkesparekassen in the dashboard and approve access on the bank's login page.

Can the CLI connect my Folkesparekassen account?

No. The CLI and SDK only read and sync connections you have already approved in the dashboard; there is no connect command.

Can open-banking.io see my transactions?

No. It is zero-knowledge and stores only your public key. Data is decrypted on your device with a private key that never leaves it.
