bunq API Access — Sync Your Dutch bunq Accounts

Founded in Amsterdam, bunq is one of Europe's best-known neobanks — and open-banking.io lets you pull its data into your own tools without touching a single certificate. Through one unified endpoint you can keep bunq balances and transaction history in sync with your app, spreadsheet, or accounting stack in near real time.

bunq runs on a fully digital model, and our integration mirrors that: a clean API call replaces manual CSV exports and screen-scraping. Whether you hold a personal or a business account, the same connection covers it.

How to connect bunq

  1. Register for an open-banking.io account and grab your API key.
  2. Call the connect endpoint and select bunq (Netherlands) as the institution.
  3. Approve access in the bunq app using your usual strong customer authentication.
  4. Receive your token and start requesting account data straight away.

What data you can access

  • Accounts — identifiers, currency, and IBAN details (BIC BUNQNL2AXXX).
  • Balances — current and available amounts, refreshed on demand.
  • Transactions — dated entries with counterparties, amounts, and descriptions.

both personal and business account types are supported.

A single bunq authorisation stays valid for up to 180 days before the account holder re-approves. open-banking.io reaches beyond bunq to 2,600+ banks across the EU and UK, so one integration scales to every institution your users bank with.

Privacy by design

We operate on a zero-knowledge basis: credentials flow directly between you and bunq, never stored on our side. There are no eIDAS certificates to buy, renew, or manage — the compliance overhead that usually blocks smaller teams simply disappears.

Pricing

Flat access from roughly EUR 3/month, with no per-call surcharges or setup fees. Predictable cost, full coverage.

Is my bunq login safe?

Yes. Authentication happens inside bunq's own environment, and open-banking.io never sees or retains your password.

Do I need a certificate to start?

No. The API is entirely certificate-free — sign up and connect the same day.

How often can I refresh data?

As often as your workflow needs within the 180-day consent window; balances and transactions update on each request.
