UniCredit Bank Slovenia API Access & Open Banking

Reaching your UniCredit Bank Slovenia accounts programmatically usually means wrestling with PSD2 certificates, sandbox registrations and per-bank paperwork. open-banking.io removes all of that. It is a certificate-free, zero-knowledge gateway to 2,600+ banks across the EU and UK, so a single account lets you pull balances and transactions from UniCredit Bank Slovenia the same way you would from any other supported institution — without ever handing your financial data to a third party in readable form.

UniCredit Bank Slovenia (Ljubljana) supports both business and personal accounts through open-banking.io, and a single consent stays valid for up to 180 days before you renew it. No BIC is required on your side to get started.

How to connect UniCredit Bank Slovenia

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 an open-banking.io account.
  2. Set your encryption passphrase. Your cryptographic keys are generated locally on your own device, so only you ever hold the private key.
  3. In the dashboard, search for and select UniCredit Bank Slovenia, then choose the account type (business or personal).
  4. You are redirected to UniCredit Bank Slovenia's own secure login and consent screen, where you approve access directly with the bank (standard PSD2 authorisation).
  5. Your approved accounts then sync back into your dashboard, ready to view.

Access your data

Reading the data programmatically is an optional developer step you take after the connection exists. On the Developers page, create an API key and export a credentials.json file — this bundles the API key with your private decryption key. From there you can 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.

Because open-banking.io is zero-knowledge, its servers only ever hold your public key — they cannot read or decrypt your UniCredit Bank Slovenia data. An API key alone returns nothing but ciphertext without your private key. All of this runs at roughly EUR 3/month.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free; you authorise access directly on UniCredit Bank Slovenia's login screen.

Can open-banking.io see my transactions?

No. Data is decrypted only on your device with a key that never leaves it. The service is zero-knowledge by design.

How long does one authorisation last?

Up to 180 days for UniCredit Bank Slovenia, after which you re-approve access to keep syncing.
