Aasen Sparebank API Access & Open Banking Data

Pulling your Aasen Sparebank balances and transactions into your own tools normally means wrestling with PSD2 certificates and sandbox paperwork. open-banking.io removes that entirely. It gives you a single, certificate-free path to your Aasen Sparebank data across both business and personal accounts, and it does so without ever being able to read what flows through it. Your data is decrypted locally with an encryption key that only you hold — the service is genuinely zero-knowledge and keeps nothing but your public key.

Aasen Sparebank is one of 2,600+ European banks reachable this way. There is no published BIC on file for this bank, so you simply select it by name when you connect.

How to connect Aasen 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 an encryption passphrase. Your keys are generated right there on your own device, so the service never sees them.
  2. In the dashboard, pick Aasen Sparebank from the bank list and choose the account type you want — business or personal.
  3. You are redirected to Aasen Sparebank's own secure login, where you approve access under PSD2. Your consent stays valid for up to 180 days before you renew it.
  4. Once approved, your accounts sync straight into your dashboard, ready to view.

That is the whole flow. You authorise directly with the bank, not through any third-party redirect you have to build yourself.

Access your data

Want to read Aasen Sparebank data programmatically? That is an optional step, and only after the connection above exists. Open 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:

  • Use the CLI: openbanking accounts, openbanking transactions, openbanking sync.
  • Or reach for an SDK or the REST API directly.

Every request carries the X-Api-Key header, and every response is decrypted locally with your own key. An API key on its own only returns ciphertext — without your private key there is nothing readable to see. The CLI and SDKs only read and sync connections that already exist; they cannot create one.

All of this runs for about EUR 3 per month.

Does open-banking.io need an eIDAS certificate?

No. The service is certificate-free — you never generate or upload a PSD2 certificate to reach Aasen Sparebank.

Can open-banking.io see my Aasen Sparebank transactions?

No. It holds only your public key. Decryption happens on your device, so the servers only ever store ciphertext.

Up to 180 days per approval. After that you re-approve on Aasen Sparebank's own login screen to keep syncing.
