DNB API Access to DNB Germany Business Accounts

Pulling live data out of your DNB (Germany) accounts no longer means wrestling with bank certificates or bespoke integrations. open-banking.io gives your software a single, consistent endpoint for reading DNB balances and transaction history, so treasury tools, accounting systems and internal dashboards stay in step with what the bank actually shows. Connect once and let the data flow on your schedule.

How to connect DNB

  1. Create an open-banking.io account and generate your API key.
  2. Select DNB (BIC DNBADEHX) from the supported institution list.
  3. Redirect the account holder to DNB's secure login to approve access.
  4. Receive the authorised connection token and begin querying immediately.
  5. Refresh balances and transactions on your own cadence via the same endpoint.

What data you can read

  • Accounts — identifiers and metadata for connected DNB business accounts.
  • Balances — current and available figures, refreshed on demand.
  • Transactions — booked movements with amounts, counterparties and dates for reconciliation and cash-flow reporting.

DNB access under open-banking.io covers business account types. A single authorisation stays valid for up to 180 days, the regulatory maximum, before the account holder is prompted to renew — so long-running integrations keep working without constant re-approval. DNB is one of 2,600+ banks reachable through the same interface, meaning the code you write for DNB carries straight over to the next institution.

Privacy by design

The platform is zero-knowledge: credentials are never seen or stored by us, and your account data passes through without being retained. There are no eIDAS or QWAC certificates to buy, provision or rotate — the heavy compliance machinery sits with open-banking.io, not with you. You get read access to the accounts you are authorised for and nothing more.

Pricing

One flat subscription of roughly EUR 3/month covers DNB and every other supported bank. No per-call metering, no setup fees, no certificate costs — predictable pricing whether you connect one account or scale across the whole network.
