Oppdalsbanken API Access & Open Banking Data

Pulling your Oppdalsbanken balances and transactions into your own tools no longer means chasing PSD2 certificates or maintaining a bespoke integration. open-banking.io gives you a single, standardised route to Oppdalsbanken data across the bank's business and personal accounts, and it works the same way for every one of the 2,600+ EU and UK institutions on the network. There is nothing to register with a regulator and no certificate to renew — you set up an account, grant consent, and your data flows in encrypted.

The privacy model is the point of difference. Your encryption keys are generated locally on your device, and open-banking.io only ever holds your public key. That means the service is zero-knowledge: it stores and moves ciphertext it cannot read, and every payload is decrypted on your machine with a key only you hold.

How to connect Oppdalsbanken

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 keys are created on your own device at this moment.
  2. In the dashboard, choose Oppdalsbanken and pick the account type you need — business or personal.
  3. You are redirected to Oppdalsbanken's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Once approved, your accounts sync back into your dashboard and stay refreshed for the life of the consent — up to 180 days, after which you simply re-approve.

Oppdalsbanken does not publish a BIC on the network (BIC: n/a), so just select it by name in the dashboard list.

Access your data

Once Oppdalsbanken is connected, developers can optionally read the data programmatically. On the Developers page, create an API key and export a credentials.json — this 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. Requests authenticate with the X-Api-Key header, and each response is decrypted locally with your own key — the API key alone only ever returns ciphertext. Note that these tools read and sync existing connections; the bank link itself is always made in the dashboard.

All of this runs at roughly EUR 3/month.

Do I need an eIDAS certificate for Oppdalsbanken?

No. open-banking.io is certificate-free — you authorise access on Oppdalsbanken's consent screen and never touch PSD2 certificates.

Can open-banking.io see my Oppdalsbanken transactions?

No. It holds only your public key and stores encrypted data. Decryption happens on your device, so the service cannot read your accounts.

Up to 180 days per approval. When it expires, re-approve Oppdalsbanken in the dashboard to keep syncing.
