Íslandsbanki API Access & Open Banking Data | open-banking.io

Reaching your Íslandsbanki account data no longer requires a bank-issued certificate or a stack of eIDAS paperwork. open-banking.io links to Íslandsbanki through regulated PSD2 access and streams your balances and transactions into a single dashboard — while keeping the data encrypted with a key that never leaves your device. That means open-banking.io's servers hold only your public key and can never read what syncs through them.

Both personal and business Íslandsbanki accounts are supported. Íslandsbanki does not publish a public BIC for this route (marked n/a), and each authorisation you grant stays valid for up to 180 days before Íslandsbanki asks you to re-confirm. With more than 2,600 European banks reachable the same way, one workflow covers Íslandsbanki alongside the rest of your institutions.

How to connect Íslandsbanki

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 own device.
  2. In the dashboard, choose Íslandsbanki and select whether you're linking a personal or business account.
  3. You're redirected to Íslandsbanki's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Once Íslandsbanki confirms, your accounts sync back into your dashboard and stay refreshed for the 180-day consent window.

Access your data

Reading the data programmatically is an optional developer step you take after the connection exists. Open 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. 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 — without your private key, there's nothing readable to see.

Is there a connect command in the CLI?

No. The CLI and SDKs only read or sync connections that already exist. Linking Íslandsbanki always happens in the dashboard via the bank's consent screen.

Can open-banking.io staff see my Íslandsbanki transactions?

No. The design is zero-knowledge — servers hold only your public key, so data is decrypted exclusively on your device.

How much does it cost?

Access is roughly EUR 3 per month, covering Íslandsbanki and every other supported bank.
