bunq (Poland) API Access — Connect Your Data | open-banking.io

Bring your bunq (Poland) account into any app or dashboard you build. open-banking.io gives you a single, standardised way to read live account, balance, and transaction data from bunq — no certificates to provision, no bank-by-bank contracts, and no infrastructure to maintain. Whether you are reconciling business payments or building a personal finance view, the connection stays consistent across every institution you add.

How to connect bunq

  1. Create an open-banking.io account and grab your API key.
  2. Call the connect endpoint and select bunq from the Polish institution list.
  3. Approve access in bunq's own secure login — your credentials go straight to the bank, never to us.
  4. Receive a consent token and start pulling data instantly.

What data you can access

  • Accounts — personal and business bunq accounts, with identifiers and metadata.
  • Balances — current and available amounts, refreshed on demand.
  • Transactions — dated entries with counterparties, amounts, and references for reconciliation or categorisation.

bunq offers both personal and business account types through the API. Consent under PSD2 runs for a maximum of 180 days, after which the account holder simply re-authorises. bunq does not expose a routable BIC for this connection, so you identify accounts through the standard bunq identifiers returned in each response. open-banking.io connects 2,600+ banks across the EU and UK, so bunq sits alongside every other institution behind one integration.

Privacy by design

The platform is zero-knowledge: we relay your authorised requests without storing or reading your banking data. There are no eIDAS certificates or QWAC files to obtain — the certificate-free model removes the biggest hurdle to open-banking integration, so you go from sign-up to live data in minutes rather than weeks.

Pricing

One flat plan of roughly EUR 3/month covers your access — no per-call surcharges, no setup fees, no per-bank pricing tiers.

FAQ

Does bunq in Poland need a separate agreement?

No. Your open-banking.io subscription already covers bunq alongside every other supported institution. Just select it and authorise.

How often can I refresh bunq balances and transactions?

You can request fresh data on demand for the life of the consent, up to the 180-day maximum before re-authorisation is required.

Can I connect both personal and business bunq accounts?

Yes. bunq exposes personal and business account types, and both are available through the same API flow.
