bunq API Access in Slovenia | Open Banking

Looking to pull your bunq data into your own tools without wrestling with bank-specific integrations? open-banking.io gives you a single, standardised way to sync bunq accounts in Slovenia — reading live balances and transaction history through one clean API instead of a patchwork of connectors.

bunq is a Dutch neobank operating across the EU, including Slovenia, so its accounts are reachable through the same PSD2 rails everything else on our platform uses. Whether you run personal finances or a business, the flow below is the same.

How to connect bunq

1. Create an open-banking.io account and grab your API key.
2. Select bunq from our list of 2,600+ supported European banks.
3. Send your user to bunq's own login to approve secure access.
4. Receive the authorised connection and start reading data immediately.

What data you can access

• Accounts — personal and business account details and metadata.
• Balances — up-to-date available and booked balances.
• Transactions — historic and incoming transaction records with counterparties, amounts and dates.

Consent and coverage

bunq supports both personal and business account types through our API. A single user consent stays valid for up to 180 days before it needs to be renewed, so you can keep data flowing without constant re-authorisation prompts. No BIC is required to set up the connection.

Privacy by design

We built open-banking.io to be zero-knowledge: your users' banking credentials go straight to bunq and never touch our servers. There are no eIDAS certificates to buy, no QWAC or QSEAL setup, and no compliance overhead on your side — we handle the regulated plumbing so you don't have to.

Pricing

One flat plan of roughly EUR 3 per month covers your access to bunq and every other bank in our network. No per-call fees, no per-bank surcharges, no surprises.
