Müritz-Sparkasse API Access & Open Banking Data

Pulling your Müritz-Sparkasse balances and transactions into your own tools shouldn't require an eIDAS certificate, a bank sponsorship or a compliance project. open-banking.io gives individuals and developers PSD2 access to Müritz-Sparkasse (BIC NOLADE21WRN) through a single dashboard, then hands the raw data back to you — decrypted only on your device. Both business and personal accounts are supported, and a single consent stays valid for up to 180 days before you re-approve.

How to connect Müritz-Sparkasse

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

  1. Sign up for an open-banking.io account.
  2. Set your encryption passphrase. The encryption keys are generated locally on your own device, so no one else — not even open-banking.io — can reconstruct them.
  3. In the dashboard, pick Müritz-Sparkasse from the bank list and choose the account type you want to link (business or personal).
  4. You're redirected to Müritz-Sparkasse's own secure login, where you approve access on the bank's PSD2 consent screen.
  5. Your accounts sync back into the dashboard, ready to view.

That's the whole flow. You authorise directly with the bank; open-banking.io never sees your banking credentials.

Access your data

Once Müritz-Sparkasse is connected, developers can optionally read that data programmatically. Open the Developers page, create an API key and export a credentials.json — this 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 directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your key. The API key alone only ever returns ciphertext — without your private key the payload stays unreadable, which is what makes the service genuinely zero-knowledge.

No certificates, no bank onboarding, just ~EUR 3/month across 2,600+ EU/UK banks.

Do I need a developer account to use this?

No. Viewing your Müritz-Sparkasse accounts in the dashboard needs nothing technical. The API key and CLI are an optional layer for those who want programmatic access.

Can open-banking.io read my Müritz-Sparkasse data?

No. The servers hold only your public key. Decryption happens on your device with a private key that never leaves it.

How long does access last before I re-approve?

Müritz-Sparkasse permits a consent window of up to 180 days, after which you simply re-approve on the bank's login screen.
