Access bunq Slovakia Data — bunq Open Banking API

bunq operates across Slovakia as a mobile-first European bank, and many of its users eventually want their balances and transactions somewhere other than the app — a spreadsheet, an accounting tool, or a script. open-banking.io gives you that reach without wrestling with PSD2 certificates or provider onboarding. It links to bunq under the same regulated open-banking rules the app already uses, then hands the raw data back to you in a form only you can unlock. Because the platform is zero-knowledge, it never holds a readable copy of anything: your encryption keys are generated on your own device, and open-banking.io stores only your public key.

How to connect bunq

Connecting happens entirely inside the open-banking.io dashboard — there is no code, endpoint, or key involved in this step. First, sign up and set an encryption passphrase; this creates the key pair that keeps your data private. Next, open the dashboard, search for bunq (Slovakia), and choose the account type you hold — both personal and business are supported. You are then redirected to bunq's own secure login, where you approve access on the bank's consent screen exactly as PSD2 requires. Once confirmed, your bunq accounts sync straight into your dashboard. Consent lasts up to 180 days, after which a quick re-approval on bunq's screen renews it. bunq does not publish a single fixed BIC for this connection, so none is needed here.

Access your data

After bunq is connected, developers can optionally read the data programmatically. On the Developers page, generate an API key and export a credentials.json — this bundles the API key together with your private decryption key. From there the CLI (openbanking accounts, openbanking transactions, openbanking sync), the SDKs, and the REST API all work the same way: every request carries an X-Api-Key header, and each response is decrypted locally with your own key. These tools only read and sync connections you already made in the dashboard — they cannot create one. An API key on its own returns nothing but ciphertext without your private key.

Does open-banking.io ever see my bunq data?

No. It is zero-knowledge and holds only your public key; decryption happens on your device with a key you alone control.

Can I connect bunq from the command line?

No. Connecting is a dashboard-only flow via bunq's consent screen. The CLI and SDKs only read existing connections.

What does it cost?

Around EUR 3 per month, covering access to bunq and 2,600+ other EU and UK banks — no certificates required.
