N26 Slovakia API Access & Open Banking | open-banking.io

Reaching your N26 (Slovakia) account data no longer means wrestling with eIDAS certificates or a bank sandbox. open-banking.io is a certificate-free bridge to 2,600+ EU and UK banks that hands you a single, consistent view of your finances — while keeping the raw data encrypted under a key that never leaves your device. Whether you hold an N26 personal or business account in Slovakia, the path is the same: connect once in the dashboard, then read the data however suits you.

Because the platform is zero-knowledge, our servers only ever store your public key. Every balance and transaction is decrypted locally, so nobody at open-banking.io — or anyone who breached us — could read your N26 statements. All of this runs for roughly EUR 3/month.

How to connect N26

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 your encryption passphrase. Your keys are generated right there on your own device.
  2. In the dashboard, search for N26 and choose your account type — business or personal.
  3. You're redirected to N26's own secure login, where you approve access under PSD2. open-banking.io never sees your credentials.
  4. Your accounts sync back into the dashboard. Your consent lasts up to 180 days, after which you simply re-approve on N26's screen.

N26 does not publish a public BIC for this connection, so none is required — selecting the bank in the dashboard is all you need.

Access your data

Once N26 is connected, developers can optionally read it programmatically. 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 use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests carry your key in the X-Api-Key header, and every response is decrypted locally with your own key. Without that private key, an API key alone returns nothing but ciphertext. Note these tools only read and sync existing connections — the initial connect always happens in the dashboard.

FAQ

Do I need an eIDAS certificate for N26?

No. open-banking.io is certificate-free. You approve access directly on N26's login screen, and we handle the PSD2 plumbing.

Can open-banking.io read my N26 transactions?

No. The service is zero-knowledge and holds only your public key. Data is decrypted on your device with a private key only you possess.

How often do I re-authorise?

N26 grants consent for up to 180 days. When it lapses, re-approve on N26's own screen from the dashboard.
