bunq API Access in Germany | open-banking.io

Pull your bunq (Germany) data into any product or workflow without building bank integrations from scratch. open-banking.io gives you a single REST endpoint that syncs bunq accounts, balances and transaction history — so you can focus on what you build with the data instead of the plumbing behind it.

bunq is the Amsterdam-born mobile bank operating across the EU, and its German customers (routed under BIC BUNQDE82XXX) can be reached through the same standardised connection we expose for every institution.

How to connect bunq

1. Create an open-banking.io account and generate an API key.
2. Call our endpoint with bunq (Germany) as the target institution.
3. Redirect the customer to bunq's secure login to approve access.
4. Receive a reusable token and start reading account data immediately.

No eIDAS certificates, no per-bank onboarding, no signed agreements — the flow is identical whether you connect one bunq account or a thousand.

What data you can access

• Accounts — identifiers and metadata for personal and business account types
• Balances — live and booked balance values
• Transactions — dated entries with counterparties, amounts and references

Consent and coverage

A single bunq authorisation stays valid for up to 180 days, after which the customer simply re-approves. bunq is one of 2,600+ banks already live on open-banking.io, so adding neighbouring institutions later means no extra integration work.

Privacy by design

We run a zero-knowledge, certificate-free model. Your customer's credentials go straight to bunq and never touch our servers, and because we don't require you to hold your own banking certificates, the compliance overhead sits with us, not you.

Pricing

Flat access from roughly EUR 3/month — no setup fees, no per-call surprises, and the same rate regardless of how many of the supported banks you connect.

FAQ

Does open-banking.io support bunq business accounts?

Yes. Both personal and business account types are covered, returning accounts, balances and transactions through the same endpoint.

How often does a bunq customer re-authorise?

Each consent lasts up to 180 days. When it lapses, the customer completes a quick re-approval at bunq to keep the connection active.

Do I need my own certificates to connect bunq?

No. Our certificate-free architecture removes the eIDAS and licensing requirements you would normally face when integrating a bank directly.
