BKS Bank Slovakia API Access & Open Banking

Reaching your BKS Bank data in Slovakia used to mean chasing eIDAS certificates and PSD2 sandbox paperwork. open-banking.io removes all of that. It is a certificate-free bridge to 2,600+ EU and UK institutions, and every balance and transaction that lands in your dashboard is decrypted on your own device with a key that never leaves it.

BKS Bank in Slovakia — the local branch of the Austrian BKS Bank AG — is fully covered. Both business and personal accounts are supported, and a single approval keeps your access live for up to 180 days before you renew. There is no published BIC for this branch, so open-banking.io identifies it by name in the dashboard rather than by SWIFT code.

How to connect BKS Bank

Connecting happens entirely inside the open-banking.io dashboard — there is no code, endpoint, or key involved in this step.

  1. Sign up for an account and set an encryption passphrase. Your key pair is generated locally at this moment, so only you ever hold the private half.
  2. In the dashboard, search for BKS Bank and choose whether you are linking a business or personal account.
  3. You are redirected to BKS Bank's own secure login, where you confirm the PSD2 consent directly with the bank.
  4. Once approved, your accounts flow back into the dashboard and begin syncing.

Because open-banking.io is zero-knowledge, its servers only ever store your public key. They relay ciphertext — they cannot read a cent of your BKS Bank activity.

Access your data

Want to work with the data in code? That is an optional developer step you take after the connection exists. On the Developers page, create an API key and export a credentials.json bundling that key together with your private decryption key. Then reach for 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 key — an API key alone returns only ciphertext.

All of this runs for around EUR 3/month.

Do I need a certificate to access BKS Bank?

No. open-banking.io handles PSD2 access for you, so no eIDAS certificate or sandbox registration is required.

Can the CLI connect my BKS Bank account?

No. The CLI and SDK only read and sync connections that already exist. Linking BKS Bank always happens in the dashboard via the bank's consent screen.

Who can read my transaction data?

Only you. Decryption uses a private key held on your device; open-banking.io stores just your public key and can never see your data.
