Addiko Bank Slovenia API Access & Open Banking

Addiko Bank is a retail-focused lender operating across Slovenia and the wider Adriatic region, and open-banking.io lets you reach its account data without wrestling with PSD2 certificates or eIDAS onboarding. Whether you bank with Addiko for a business or a personal account, you can bring balances and transactions into one encrypted dashboard and, if you code, pull them programmatically afterwards. Everything stays private: open-banking.io is zero-knowledge, so your financial data is decrypted only on your own device with a key that never leaves your hands.

How to connect Addiko Bank

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, key, or code involved in linking your bank:

  1. Sign up for an open-banking.io account.
  2. Set an encryption passphrase. Your keys are generated locally on your device, so only you can later decrypt what you sync.
  3. In the dashboard, choose Addiko Bank (Slovenia) and select the account type — business or personal.
  4. You are redirected to Addiko Bank's own secure login to approve access (standard PSD2 consent). You authenticate directly with the bank; open-banking.io never sees your credentials.
  5. Once approved, your Addiko accounts sync into the dashboard. Consent lasts up to 180 days, after which you simply re-approve on Addiko's screen.

Addiko Bank Slovenia has no published BIC in our records, so selecting it by name in the dashboard is the reliable route.

Access your data

After your Addiko connection is live, developers can optionally read it in code. 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command, and an API key alone returns nothing but ciphertext without your private key.

All of this runs for around EUR 3/month, with no certificate or license application to file.

Does open-banking.io store my Addiko login or data?

No. You log in on Addiko Bank's own consent screen, and your synced data is encrypted so that only your device holds the key. The service keeps just your public key.

Can I connect an Addiko business account?

Yes. Both business and personal Addiko Bank accounts are supported — pick the type when you select the bank in the dashboard.

How long does access last?

Up to 180 days per consent. When it expires, re-approve access on Addiko Bank's login screen to keep syncing.
