bunq API Access (Belgium) | open-banking.io

Looking to pull your bunq data in Belgium into your own app, dashboard or accounting stack? open-banking.io gives you a single, standards-based gateway to bunq's Belgian personal and business accounts — no bank-specific integration work, no eIDAS certificates, and no bunq developer contract to negotiate. Authenticate once, and keep account and payment information flowing automatically.

How to connect bunq

1. Create an open-banking.io account and generate your API key.
2. Send a connection request naming bunq (Belgium) as the target institution.
3. Redirect the account holder to bunq's secure login to approve access.
4. Receive the confirmation callback and begin reading data through one consistent REST endpoint.

What data you can access

• Accounts — identifiers and metadata for personal and business accounts.
• Balances — current and available balances, refreshed on demand.
• Transactions — booked and pending entries with counterparties, amounts and dates.

Consent and coverage

A single user authorisation stays valid for up to 180 days before the account holder needs to re-approve. bunq publishes no dedicated BIC for this connection, so open-banking.io routes requests by institution rather than by BIC. Both personal and business account types are supported. Alongside bunq, the same API reaches 2,600+ banks across the EU and UK, so adding further institutions later needs no new integration.

Privacy and security

open-banking.io is built on a zero-knowledge model: your credentials and account data are never mined, resold or repurposed. The service is certificate-free, removing the QWAC/QSEAL burden that normally blocks smaller teams from PSD2 access, while every request runs over encrypted, regulated channels.

Pricing

One flat subscription of roughly EUR 3 per month covers your bunq connection and every other supported bank — no per-call fees or hidden tiers.
