bunq API Access in Portugal | Open Banking Integration

Pulling live data out of your bunq account in Portugal no longer means wrestling with raw PSD2 endpoints or provisioning eIDAS certificates. open-banking.io gives you a single, tidy interface to sync bunq balances and payment history into whatever you're building — a spending dashboard, an accounting sync, a treasury tool, or a personal finance script. bunq operates across the EU as a Dutch neobank, and Portuguese customers connect through the same standardised flow used for 2,600+ other banks.

How to connect bunq

1. Create an account on open-banking.io and open the connection dashboard.
2. Search for bunq and pick Portugal as the country of your account.
3. Choose whether you're linking a personal or business profile.
4. Approve the request inside your bunq app to authorise data sharing.
5. Start reading structured account data through the unified API immediately after consent.

What data you can access

Once the link is live, you can retrieve:

• Accounts — identifiers and metadata for each bunq account you hold.
• Balances — current and available amounts, refreshed on demand.
• Transactions — dated entries with counterparties, references and amounts for reconciliation and analysis.

Consent and coverage

bunq supports both personal and business account types through the connection. A single authorisation stays valid for up to 180 days, the maximum consent window under the standard, after which you simply prompt a re-approval. bunq does not expose a public BIC in this integration, so connections are keyed by bank and country rather than SWIFT code.

Privacy by design

The platform is zero-knowledge: your data passes through to you without being mined, resold or stored for profiling. There's no certificate to buy, register or renew — no eIDAS QWAC, no signing keys to rotate. You authenticate directly with bunq, and open-banking.io never holds your banking credentials.

Pricing

One flat subscription of roughly EUR 3 per month covers bunq access alongside every other supported institution — no per-call metering, no enterprise contract, no setup fee.

FAQ

Is a certificate needed to connect bunq?

No. open-banking.io handles the regulated access layer, so you skip eIDAS certificates entirely and just authorise in-app.

How long does a bunq connection last?

Each consent runs up to 180 days. When it expires, a quick re-authorisation in the bunq app restores the link.

Can I link a business bunq profile?

Yes. Both personal and business bunq accounts in Portugal are supported through the same flow.
