DNB Corporate Mastercard API Access | Open Banking

Bring your DNB Corporate Mastercard data into your own tools without wrestling with bank portals or PSD2 certificates. open-banking.io gives you a single, standardised API to read your DNB business card accounts, check balances and pull transaction history — ideal for expense automation, bookkeeping, reconciliation and cash-flow dashboards. Instead of exporting CSVs by hand each month, you connect once and keep card data flowing.

How to connect DNB Corporate Mastercard

1. Create an account at open-banking.io and select DNB (Norway) as your institution.
2. Choose the DNB Corporate Mastercard business account you want to link.
3. Authenticate directly in DNB's own secure environment — your credentials are never seen by us.
4. Approve the consent scope for account, balance and transaction access.
5. Start querying the unified API, or wire it into your accounting or ERP system.

What data you can access

• Accounts — identifiers and metadata for your DNB Corporate Mastercard business accounts.
• Balances — current and available balances for spend tracking.
• Transactions — line-by-line card movements for reconciliation and reporting.

Consent and coverage

DNB Corporate Mastercard is available as a business account type. Consent can be granted for up to 180 days before a straightforward re-authentication is required, so long-running integrations stay live with minimal friction. open-banking.io connects to 2,600+ banks across the EU and UK, letting you standardise every card and account relationship behind one interface.

Privacy by design

We operate a zero-knowledge, certificate-free model. You never buy, install or renew eIDAS/QWAC certificates, and your banking login is entered only inside DNB's authentication flow. Data passes through a consent you control and can revoke at any time.

Pricing

Flat, predictable access from around EUR 3 per month — no per-call surcharges or setup fees, so scaling across accounts stays affordable.
