VÚB banka API Access & Open Banking Data | open-banking.io

Whether you run a company or manage personal finances in Slovakia, open-banking.io gives you a single, private place to pull your VÚB banka balances and transactions together. There is nothing to install on VÚB banka's side and no certificate to register — you approve access once through the bank's own login, and your data streams into a dashboard where only you hold the decryption key.

open-banking.io covers 2,600+ banks across the EU and UK under PSD2, so VÚB banka can sit alongside every other account you hold. Both business and personal account types are supported, and each consent you grant stays valid for up to 180 days before VÚB banka asks you to renew it.

How to connect VÚB banka

Connecting happens entirely inside the open-banking.io dashboard — no API call, key, or code is part of this step:

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally on your own device, so the passphrase never leaves it.
  2. In the dashboard, choose VÚB banka from the bank list and select the account type you want to link (business or personal).
  3. You are redirected to VÚB banka's own secure login, where you authenticate and approve the PSD2 consent directly with the bank.
  4. Once approved, your VÚB banka accounts sync into your dashboard and refresh automatically for the life of the consent.

Because the flow runs through VÚB banka's genuine login, open-banking.io never sees your banking credentials.

Access your data

Want your VÚB banka data in code? That is an optional developer step you take after connecting. On the Developers page, create an API key and export a credentials.json — it 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. An API key on its own only ever returns ciphertext.

This is what zero-knowledge means here: open-banking.io stores only your public key and can never read your VÚB banka data. All of it for roughly EUR 3/month.

Does connecting VÚB banka need a certificate or developer account?

No. You approve access in the dashboard through VÚB banka's login. The Developers page and API keys are optional extras for reading data later.

Can the CLI connect my VÚB banka account?

No. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command.

How long does my VÚB banka access last?

Up to 180 days per consent, after which VÚB banka prompts you to reauthorise.
