DNB Finland API Access | DNB API via Open Banking

Pulling live data out of DNB (Finland) usually means wrestling with eIDAS certificates, sandbox onboarding and per-bank PSD2 quirks. open-banking.io removes that overhead: one integration reaches DNB and 2,600+ other banks across the EU and UK, so you can sync DNB account data into your own product, ledger or dashboard without ever touching a signing certificate.

DNB's Finland branch (BIC DNBAFIHX) serves corporate clients, and our unified API exposes its data through a single, consistent schema. Whether you're building treasury tooling, reconciliation flows or a reporting layer, you read DNB the same way you read every other connected bank.

How to connect DNB

  1. Create an open-banking.io account and generate an API key.
  2. Call the connect endpoint and select DNB (Finland) from the bank list.
  3. Redirect your user to DNB's own login for strong customer authentication.
  4. On approval, receive a secure access token — no certificates, no manual paperwork.
  5. Start requesting accounts, balances and transactions immediately.

What data you can access

  • Accounts — business account identifiers and metadata for the DNB Finland branch.
  • Balances — current and available balances, refreshed on demand.
  • Transactions — booked and pending entries with amounts, dates and counterparties, ready for categorisation or reconciliation.

DNB (Finland) supports account access under a consent that stays valid for up to 180 days before the account holder needs to re-authenticate. Account coverage here is focused on business accounts, matching the branch's corporate profile. When consent nears expiry, simply prompt the user to re-authorise and the connection continues uninterrupted.

Privacy by design

We operate a zero-knowledge model: your users' banking credentials are entered only on DNB's own pages, never on ours, and we don't store the data flowing through your integration. The service is certificate-free, so there's no eIDAS setup, no key rotation and no compliance burden shifted onto your team.

Pricing

Access to DNB and every other supported bank starts at roughly EUR 3 per month — one flat, predictable price with no per-bank fees or hidden setup costs.
