Nord-Ostsee Sparkasse API Access | open-banking.io

Bring Nord-Ostsee Sparkasse (Nospa) account data straight into your own software with open-banking.io. Our unified EU/UK banking API lets you pull live balances and transaction history from the Schleswig-based Sparkasse (BIC NOLADE21NOS) without maintaining your own PSD2 connection, eIDAS certificates, or bank-specific plumbing. One integration reaches Nospa alongside 2,600+ other institutions.

Whether you are building bookkeeping automation, a treasury dashboard, or personal finance tooling, open-banking.io handles the authentication handshake and keeps the link refreshed so you can focus on what you do with the data.

How to connect Nord-Ostsee Sparkasse

  1. Create an open-banking.io account and generate your API key.
  2. Call the connect endpoint and select Nord-Ostsee Sparkasse from the institution list.
  3. Authenticate with your Nospa online-banking credentials and approve consent in the bank's own environment.
  4. Receive an access token and begin querying accounts, balances, and transactions immediately.

What data you can access

  • Accounts — business and personal account details and metadata.
  • Balances — up-to-date booked and available balances.
  • Transactions — dated transaction records with counterparties and references for reconciliation.

Nospa supports both business and personal accounts. Each user consent stays valid for up to 180 days, after which the account holder simply re-authenticates to keep the connection active. Coverage runs through the same standardized flow used across our entire German bank catalogue.

Privacy by design

open-banking.io is zero-knowledge: your customers' credentials are entered only within the bank's authentication screen, never stored by us. There are no eIDAS or QWAC certificates for you to buy, install, or renew — we abstract the compliance layer entirely, so you ship faster and hold less sensitive data.

Pricing

Flat, predictable access from roughly EUR 3 per month. No per-call surprises and no separate certificate costs — one subscription covers Nord-Ostsee Sparkasse and every other supported institution.

Is a special certificate required to reach Nospa?

No. open-banking.io is certificate-free; we manage all PSD2 and eIDAS requirements on your behalf.

Which Nord-Ostsee Sparkasse accounts are supported?

Both business and personal accounts can be connected and read through the API.

How long does a connection last before re-authentication?

Consent remains valid for up to 180 days per the bank's policy, then the account holder re-approves access.
