Sparkasse Neubrandenburg-Demmin API & Open Banking Access

Pulling account and transaction data from Sparkasse Neubrandenburg-Demmin (BIC NOLADE21NBS) usually means wrestling with PSD2 certificates and sandbox onboarding. open-banking.io removes that: it covers 2,600+ EU/UK banks — including this Mecklenburg savings bank — and hands you a clean, decrypted feed of your own accounts. There are no eIDAS certificates to buy and no bank-specific integration to maintain. Both business and personal Sparkasse Neubrandenburg-Demmin accounts are supported, and a single consent stays valid for up to 180 days before you renew.

The design is zero-knowledge. Your encryption keys are generated on your own device, so open-banking.io's servers only ever hold your public key — they store ciphertext they cannot read. Every figure you see is decrypted locally, under a passphrase only you know.

How to connect Sparkasse Neubrandenburg-Demmin

Connecting happens entirely in the open-banking.io dashboard — there is no API call, code, or key involved in this step:

  1. Sign up for open-banking.io and set your encryption passphrase. Your private key is created locally and never leaves your device.
  2. In the dashboard, search for Sparkasse Neubrandenburg-Demmin and choose the account type you need — business or personal.
  3. You are redirected to Sparkasse Neubrandenburg-Demmin's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Control returns to your dashboard and your accounts sync in, ready to view.

That approval on the bank's own page is the only place your Sparkasse credentials are ever entered.

Access your data

Reading data programmatically is an optional step you take after connecting. On the Developers page, create an API key and export a credentials.json — it bundles the API key together with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and each response is decrypted locally with your key. The CLI and SDK only read and sync connections that already exist — they never create one. Note that an API key on its own returns only ciphertext; without your private key the data stays unreadable.

All of this runs at about EUR 3/month.

Do I need a PSD2 certificate for Sparkasse Neubrandenburg-Demmin?

No. open-banking.io is certificate-free — you approve access directly on the bank's consent screen.

Can open-banking.io see my Sparkasse balances?

No. The service is zero-knowledge and holds only your public key, so it stores encrypted data it cannot decrypt.

Up to 180 days, after which you re-approve access through the dashboard.
