Nordea (Sweden) API Access & Open Banking Data

Reaching your Nordea (Sweden) accounts programmatically usually means chasing eIDAS certificates, sandbox registrations and OAuth scopes. open-banking.io removes all of that. It is a certificate-free, zero-knowledge bridge to 2,600+ European banks, and Nordea (BIC NDEASESS) is one of them. Both business and personal accounts are supported, and a single PSD2 consent stays valid for up to 180 days before you re-approve.

The key idea: your data is encrypted with a key generated on your device. open-banking.io's servers only ever hold your public key, so they can relay ciphertext but can never read your balances or transactions.

How to connect Nordea

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

  1. Sign up for an account and set your encryption passphrase. Your key pair is created locally, in your browser, and never leaves your device.
  2. In the dashboard, search for Nordea (Sweden) and choose the account type you need — business or personal.
  3. You are redirected to Nordea's own secure login, where you authenticate and approve access on the bank's official PSD2 consent screen.
  4. Once approved, your Nordea accounts sync straight into your dashboard, ready to view.

That's the whole flow — you authorise Nordea directly, and nobody at open-banking.io ever sees your credentials.

Access your data

Want to pull the data into your own code? That's an optional step you take after connecting. On the Developers page, create an API key and export a credentials.json — it bundles your 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 authenticate with the X-Api-Key header, and every response is decrypted locally with your private key. The API key alone only ever returns ciphertext — without your key, the data stays unreadable. The CLI and SDK read and sync existing connections; they never create them.

All of this runs on the flat ~EUR 3/month plan.

FAQ

Do I need an eIDAS certificate for Nordea?

No. open-banking.io is certificate-free — you approve access on Nordea's consent screen and skip the certificate process entirely.

Can open-banking.io see my Nordea transactions?

No. It is zero-knowledge and holds only your public key. Decryption happens locally with a private key only you have.

How often do I re-authorise?

Nordea consent lasts up to 180 days, after which you simply re-approve in the dashboard.
