Nidaros Sparebank API Access & Open Banking Data

Nidaros Sparebank customers in Norway can bring their account data into a single, privacy-first workspace with open-banking.io. Whether you run a business or manage personal finances, the service reads your Nidaros Sparebank balances and transactions under PSD2 — and because it is zero-knowledge and certificate-free, everything is decrypted on your own device with a key only you hold. No eIDAS certificate, no bank-specific paperwork, and nothing readable ever sits on our servers.

How to connect Nidaros Sparebank

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 locally on your device, so only you can unlock your data later.
  2. In the dashboard, search for and select Nidaros Sparebank, then choose the account type you want to link — business or personal.
  3. You are redirected to Nidaros Sparebank's own secure login and consent screen, where you approve access directly with the bank. open-banking.io never sees your credentials.
  4. Once approved, your accounts sync into the dashboard. Your Nidaros Sparebank consent stays valid for up to 180 days, after which you simply re-approve.

Access your data

Reading your data programmatically is an optional developer step you take after connecting. On the Developers page, create an API key and export a credentials.json — this 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. An API key alone only ever returns ciphertext, keeping the zero-knowledge guarantee intact. The CLI and SDK read and sync existing connections — they never connect a bank themselves.

All of this runs on flat pricing of around EUR 3/month, with no per-bank fees.

Does Nidaros Sparebank have a BIC on open-banking.io?

No BIC is listed for Nidaros Sparebank here — you select the bank by name in the dashboard, so a BIC is not needed to connect.

Yes. Nidaros Sparebank supports both business and personal account types; add each one through the dashboard connect flow.

Can open-banking.io read my transactions?

No. The service holds only your public key, so stored data stays encrypted. Only your local device, using your private key, can decrypt it.
