Nordea Denmark API Access & Open Banking Data

Reaching your Nordea (Denmark) account data no longer means wrestling with eIDAS certificates or a bank-hosted sandbox. open-banking.io gives you PSD2 access to Nordea across the EU and UK — 2,600+ banks in one place — while keeping the raw data encrypted under a key that never leaves your device. Nordea Denmark (BIC NDEADKKK) is supported for both business and personal accounts, with consent lasting up to 180 days before you re-approve.

Because the platform is zero-knowledge, our servers only ever hold your public key. Balances and transactions are decrypted locally, so no employee, subpoena, or breach on our side can expose what's in your Nordea accounts.

How to connect Nordea

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 key pair is generated right there on your own device.
  2. In the dashboard, search for Nordea (Denmark) and choose the account type you need — personal or business.
  3. You're redirected to Nordea's own secure login, where you approve access on the bank's PSD2 consent screen. Your credentials are only ever seen by Nordea.
  4. Once approved, your Nordea accounts sync into the dashboard, refreshed automatically until the 180-day consent expires.

That's the whole flow — pick the bank, approve at Nordea, done.

Access your data

Want the data programmatically? That's an optional developer step, only after a Nordea connection already exists. Open the Developers page, create an API key, and export a credentials.json — it 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 directly. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. Note that the API key alone returns only ciphertext — without your private key there's nothing readable, which is exactly the point.

All of this runs for roughly EUR 3/month, with no certificate paperwork.

Does open-banking.io ever see my Nordea data?

No. It's zero-knowledge — we store only your public key, and decryption happens on your device.

Can the CLI connect my Nordea account?

No. The CLI and SDK only read and sync connections you've already approved in the dashboard. There is no connect command.

How long does Nordea access last?

Up to 180 days per consent, after which you re-approve on Nordea's login screen.
