ČSOB Slovakia API Access & Open Banking | open-banking.io

Reaching your ČSOB (Slovakia) accounts programmatically usually means wrestling with eIDAS certificates, sandbox registration, and PSD2 paperwork. open-banking.io removes all of that. It gives you one consistent way to view and export ČSOB data across 2,600+ EU and UK banks, without ever handling a certificate or trusting a server with your keys.

ČSOB in Slovakia supports both business and personal accounts, and a single approval keeps your access live for up to 180 days before you renew. No published BIC is required to set up the connection here.

How to connect ČSOB

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your encryption keys are generated locally on your own device, so only you can ever unlock your data.
  2. Open the dashboard and choose ČSOB (Slovakia) from the bank list, then pick the account type — business or personal.
  3. You are redirected to ČSOB's own secure login, where you approve access under PSD2 on the bank's consent screen. Your credentials go only to ČSOB.
  4. Once approved, your accounts sync straight into your open-banking.io dashboard, ready to view.

That is the whole flow. You are always the account holder approving your own access directly with ČSOB.

Access your data

After your ČSOB connection is live, developers can optionally read it 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.

Every request authenticates with the X-Api-Key header, and each response is decrypted locally with your own key. open-banking.io stores only your public key, so its servers physically cannot read your ČSOB data. An API key alone returns nothing but ciphertext without your private key — true zero-knowledge access.

FAQ

Do I need an eIDAS certificate for ČSOB?

No. open-banking.io is certificate-free. You approve access on ČSOB's own consent screen and never manage certificates yourself.

Up to 180 days per approval. When it lapses, simply re-approve in the dashboard to keep your data syncing.

Can open-banking.io see my ČSOB balances?

No. Decryption happens on your device with a key only you hold. The service stores just your public key and can never read your data.

Pricing is around EUR 3/month. Start at open-banking.io.
