Nordea First Card API Access & Open Banking (DK)

Nordea First Card is a corporate charge card used by Danish businesses to manage travel, expense and procurement spending. If you need that card data outside the issuer's own portal — in a reconciliation tool, an accounting pipeline or a custom dashboard — open-banking.io gives you a single, standardised way to reach it under PSD2, without certificates, eIDAS keys or a bank-by-bank integration project.

open-banking.io covers 2,600+ EU and UK banks and card issuers. Nordea First Card in Denmark carries the BIC NDEADKKK and issues business accounts, so this page is aimed at company card programmes rather than personal cards. Every consent you grant is valid for up to 180 days before the bank asks you to re-authorise.

How to connect Nordea First Card

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 an open-banking.io account.
  2. Set your encryption passphrase. Your keys are generated on your own device, so only you can later unlock the data.
  3. In the dashboard, search for Nordea First Card and choose the business account type.
  4. You are redirected to Nordea First Card's own secure login and consent screen, where you approve access directly with the issuer.
  5. Your card accounts and transactions sync back into your dashboard.

That's the whole flow — you authenticate on Nordea's side, never by handing credentials to us.

Access your data

Reading the data programmatically is an optional step that comes after the connection exists. On 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 you can 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 own key. The API key alone only ever returns ciphertext.

This is what zero-knowledge means here: open-banking.io stores only your public key and can never read your Nordea First Card data. All of it for around EUR 3/month.

Does connecting require an API key?

No. You connect entirely in the dashboard by approving access on Nordea First Card's own login. API keys are only for reading data afterwards.

Can the CLI connect the card for me?

No. The CLI and SDK only read and sync connections that already exist — there is no connect command. The initial consent must be granted in the dashboard.

Can open-banking.io see my transactions?

No. Data is encrypted with a key held only on your device, so our servers hold ciphertext they cannot decrypt.
