LON API Access & Open Banking Integration (Slovenia)

Reaching your LON account data no longer means wrestling with eIDAS certificates or a bespoke bank integration. open-banking.io gives you a single, certificate-free path to LON (Hranilnica LON, Slovenia) alongside 2,600+ other EU and UK banks. You approve access once on LON's own login, and your accounts flow into a dashboard where everything is decrypted locally with a key only you hold.

LON supports both business and personal accounts, and a single PSD2 consent stays valid for up to 180 days before you re-approve. Note that LON does not publish a BIC in our reference data, so you select it by name rather than by bank identifier.

How to connect LON

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 cryptographic keys are generated on your own device.
  2. In the dashboard, search for and pick LON, then choose the account type (business or personal).
  3. You are redirected to LON's own secure login, where you approve access under PSD2 — your credentials are only ever entered on the bank's page.
  4. Your LON accounts and transactions sync back into your dashboard automatically.

That's the whole flow. No developer setup is required to simply view your data.

Access your data

Once LON is 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:

  • CLI: run openbanking accounts, openbanking transactions, or openbanking sync.
  • SDK / REST API: send requests with the X-Api-Key header.

Every response is decrypted locally with your own key. The CLI and SDK only read and sync connections that already exist — they never connect a bank. Because open-banking.io is zero-knowledge, its servers hold only your public key: an API key alone returns ciphertext, never readable data.

All of this runs on flat pricing of roughly EUR 3/month, with no per-bank certificates to buy or maintain.

FAQ

Do I need a developer account to use LON?

No. Connecting and viewing LON accounts is done in the dashboard. Credentials.json and the CLI/API are optional extras for programmatic access.

Can open-banking.io read my LON transactions?

No. Data is decrypted on your device with a key only you hold. The servers store only your public key.

Up to 180 days, after which you re-approve access on LON's login screen.
