Oberbank Slovakia API Access & Open Banking Guide

Reaching your Oberbank (Slovakia) accounts programmatically usually means TPP licensing, eIDAS certificates and a sandbox onboarding. open-banking.io removes that overhead. It is a certificate-free PSD2 layer covering 2,600+ European banks, and it lets you view and export your Oberbank data without ever handing a third party the ability to read it. Every balance and transaction is encrypted and only decrypted on your own device, with a key that never leaves it.

Oberbank in Slovakia operates under BIC OBKLAT2LXXX and supports both business and personal accounts. A single approved consent stays valid for up to 180 days before Oberbank asks you to re-authorise, so once linked your data keeps flowing with minimal friction.

How to connect Oberbank

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 choose an encryption passphrase. Your cryptographic keys are generated locally on your device; the service only ever sees your public key.
  2. In the dashboard, search for Oberbank (Slovakia) and select whether you're linking a business or personal account.
  3. You are redirected to Oberbank's own secure login, where you approve the access request under PSD2 — your credentials go only to the bank.
  4. Once you confirm, your Oberbank accounts sync into the dashboard, ready to view.

That's the whole connection flow. No developer setup is required unless you want programmatic access afterwards.

Access your data

If you're a developer, reading the data is an optional step that comes after the account is already linked. 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 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. The API key alone only ever returns ciphertext — without your private key, nobody, including open-banking.io's servers, can turn it into readable data.
