OTP banka API Access & Open Banking in Slovenia

Want to read your OTP banka (Slovenia) balances and transactions from software you control? open-banking.io gives you a single, private route to your Slovenian banking data — no certificates to request, no PSD2 sandbox paperwork, and no server that can ever read what you download. OTP banka supports both business and personal accounts, and a single consent stays valid for up to 180 days before you re-approve. Note that OTP banka has no BIC listed in our directory, so you select it by name rather than by identifier.

How to connect OTP banka

Connecting happens entirely inside the open-banking.io dashboard — there is no code or API call in this step:

  1. Sign up for an open-banking.io account.
  2. Set an encryption passphrase. Your keys are generated locally on your own device, so only you ever hold the private key.
  3. In the dashboard, search for OTP banka and choose whether you're linking a business or personal account.
  4. You're redirected to OTP banka's own secure login, where you approve access on the bank's PSD2 consent screen.
  5. Your accounts sync back into the dashboard, ready to view.

That's it — the whole authorization is handled by OTP banka directly, and open-banking.io never sees your banking credentials.

Access your data

Once OTP banka is connected, developers can optionally pull the same data programmatically. On the Developers page, create an API key and export a credentials.json — this bundles your API key together with your private decryption key. From there you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. An API key on its own only ever returns ciphertext — without your private key, nobody, including open-banking.io, can read it. The CLI and SDK only read and sync connections you've already made; there's no connect command.
