DNB API Access for Denmark Bank Data Sync

Pulling live data out of DNB in Denmark no longer means wrestling with eIDAS certificates or bank-by-bank integrations. With open-banking.io you point a single API at DNB (BIC DNBADKKX) and start syncing business account data in minutes — the same endpoint that already reaches 2,600+ banks across the EU and UK.

Because the interface is uniform, code you write for DNB carries over to every other institution on the network. No sandbox onboarding marathon, no per-bank SDKs, no compliance paperwork to shepherd.

How to connect DNB

1. Create an open-banking.io account and grab your API key.
2. Call the connect endpoint and select DNB (BIC DNBADKKX) as the target institution.
3. Redirect the account holder to DNB's own login to approve access.
4. Receive the consent token and begin fetching data straight away.

What data you can access

• Accounts — business account details and metadata.
• Balances — current and available amounts, refreshed on demand.
• Transactions — booked and pending entries with counterparties, amounts and dates for reconciliation, accounting or analytics.

Consent and coverage

DNB currently exposes business account types through the API. A single authorisation stays valid for up to 180 days, the regulatory maximum, so your integration keeps syncing without asking users to re-approve every few weeks. When a consent nears expiry, simply prompt for a fresh approval.

Privacy by design

open-banking.io is zero-knowledge: we never see or store your users' banking credentials, and payloads pass through without being mined. The platform is also certificate-free — there are no QWAC or QSEAL certificates to purchase, renew or rotate. You handle DNB data; we handle the plumbing.

Pricing

Access starts at roughly EUR 3 per month, flat. One predictable fee covers DNB and the entire 2,600+ bank catalogue — no setup charges and no per-connection surprises.

FAQ

Do I need eIDAS certificates for DNB?

No. open-banking.io is certificate-free, so there is nothing to buy or maintain on your side — just your API key.
