Sparebanken Sør API Access & Open Banking Data

Sparebanken Sør is one of southern Norway's largest regional savings banks, and open-banking.io lets you reach its account and transaction data without wrestling with PSD2 certificates or a sandbox. open-banking.io is a zero-knowledge service covering 2,600+ banks across the EU and UK: your data is decrypted locally with a key that only you hold, so nobody else — not even open-banking.io's servers — can read it.

Both business and personal Sparebanken Sør accounts are supported. A single access approval stays valid for up to 180 days before Sparebanken Sør asks you to re-confirm, and no BIC is required to get started.

How to connect Sparebanken Sør

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 open-banking.io and set your encryption passphrase. Your keys are generated right on your own device.
  2. In the dashboard, pick Sparebanken Sør and choose the account type you need (business or personal).
  3. You're redirected to Sparebanken Sør's own secure login, where you approve access under PSD2.
  4. Once you confirm on the bank's consent screen, your accounts sync straight into your open-banking.io dashboard.

That's it — no manual paperwork, no eIDAS certificate, and nothing to configure with the bank directly.

Access your data

After your Sparebanken Sør accounts are 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. 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, so your data stays private end to end.

All of this runs for roughly EUR 3/month.
