bunq API Access | Connect bunq Croatia Accounts

Bringing bunq account data into your own systems no longer means wrestling with certificates or lengthy bank onboarding. With open-banking.io you can sync a bunq (Croatia) personal or business account through a single, standardised API and keep balances and transaction history flowing automatically into your tools.

bunq is a Dutch neobank that serves customers across the EU, including Croatia. Rather than integrating directly with bunq's own PSD2 interface, you connect once to open-banking.io and reach bunq alongside 2,600+ other European banks.

How to connect bunq

1. Create your open-banking.io account and generate an API key.
2. Send your user to the hosted consent screen and pick bunq (Croatia).
3. The customer authenticates directly with bunq using their own credentials.
4. bunq returns a secure authorisation — no certificates or manual setup on your side.
5. Start pulling account, balance, and transaction data through the unified endpoints.

What data you can access

• Accounts — identifiers and metadata for connected bunq accounts
• Balances — current and available balance figures
• Transactions — historical and incoming transaction records with counterparties, amounts, and dates

Both personal and business bunq accounts are supported.

Consent and coverage

A single bunq authorisation stays valid for up to 180 days before the customer needs to re-confirm, so data keeps syncing without frequent interruptions. bunq does not publish a BIC in this context, but selecting the bank from the connection screen is all that's required. open-banking.io's shared coverage spans more than 2,600 banks across the EU and UK.

Privacy by design

We run a zero-knowledge, certificate-free model. There are no eIDAS certificates to buy or renew, and credentials are exchanged only between the customer and bunq. Your integration stays lightweight while the sensitive parts stay out of your hands.

Pricing

Access is a flat rate of roughly EUR 3 per month — no per-call fees, no per-bank surcharges, and the same price whether you connect bunq or any other supported institution.

FAQ

Can I connect a bunq business account?

Each authorisation lasts up to 180 days. After that, the customer simply re-confirms to keep the connection active.

Do I need certificates to access bunq?
