Nordfyns Bank API Access & Open Banking | open-banking.io

Nordfyns Bank, the independent Danish bank rooted in Otterup on the island of Funen, serves both households and local enterprises. If you want your Nordfyns Bank balances and transactions in one programmable place, open-banking.io gives you PSD2-based access without certificates, eIDAS registration, or building your own connector. It covers 2,600+ European banks under a single account, and everything decrypts locally with a key that never leaves your device.

Both business and personal Nordfyns Bank accounts are supported, and a single approval keeps data flowing for up to 180 days before you need to renew consent. Nordfyns Bank does not publish a public BIC in our reference data, so you simply select it by name in the dashboard — no bank code to look up.

How to connect Nordfyns Bank

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 Nordfyns Bank and choose the account type you need (business or personal).
  3. You are redirected to Nordfyns Bank's own secure login, where you authenticate and approve access (standard PSD2 consent).
  4. Once approved, your accounts sync back into the dashboard automatically.

That's the whole flow. You never hand credentials to open-banking.io — the bank authenticates you directly.

Access your data

Reading the data programmatically is an optional developer 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 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 private key. The CLI and SDK only read and sync connections you already made — they cannot connect a bank.

Because open-banking.io is zero-knowledge, its servers hold only your public key. An API key alone returns ciphertext; without your private key, nobody — including open-banking.io — can read it. All of this runs for around EUR 3/month.

Does open-banking.io need an eIDAS certificate?

No. It is certificate-free — you approve access directly on Nordfyns Bank's login screen.

Can I connect both my business and personal accounts?

Yes. Both account types are supported; add each one from the dashboard.

How often do I re-authorize?

Each consent lasts up to 180 days, after which you renew it from the dashboard.
