bunq API Access in Slovakia | Open Banking Connection

Bringing your bunq data into your own tools no longer means wrestling with raw bank APIs or eIDAS certificates. With open-banking.io, a bunq account held in Slovakia connects to a single, unified endpoint that streams account details, live balances and full transaction history straight into whatever you're building — a dashboard, an accounting workflow or a personal finance tracker.

bunq is a mobile-first European bank, and its Slovak customers fall under the same PSD2 access rules as the rest of the EU. That means read access is available to both the money you can see in-app and the movements behind it.

How to connect bunq

1. Create an account at open-banking.io and open the connection wizard.
2. Search the 2,600+ supported institutions and pick bunq (Slovakia).
3. You're redirected to bunq to authenticate and approve the access request.
4. Choose whether you're linking a personal or business profile.
5. The API returns a token, and your data begins syncing immediately.

What data you can access

• Accounts — identifiers, currency and account metadata
• Balances — current and available amounts in real time
• Transactions — historical and incoming entries with counterparties and references

Consent and coverage

bunq supports both personal and business account types through the API. Each authorisation lasts up to 180 days before bunq asks you to re-confirm — the longest window PSD2 permits — so refreshes are infrequent. No BIC is required to establish the connection.

Privacy by design

open-banking.io runs on a zero-knowledge model: your banking credentials go only to bunq, never to us, and we don't retain copies of your financial records. There are no QWAC or QSEAL certificates to purchase, register or renew — the platform handles the regulatory plumbing so you don't touch a certificate at all.

Pricing

One flat subscription of roughly EUR 3 per month covers bunq access alongside every other bank in the network. No per-call metering, no tiered add-ons.

Does bunq in Slovakia need a special setup?

No. bunq operates EU-wide on one licence, so the Slovak connection uses the same flow as any other bunq market.

Can I link a business bunq profile?

Yes. Both personal and business bunq accounts are supported through the same API.

How often will I re-authorise?

At most every 180 days, in line with PSD2's maximum consent duration.
