Sparkasse Mecklenburg-Schwerin API & Open Banking Access

Reach your Sparkasse Mecklenburg-Schwerin accounts through a single, privacy-first dashboard. open-banking.io is a zero-knowledge, certificate-free service covering 2,600+ EU and UK banks, so you skip the eIDAS certificates and PSD2 licensing normally required to read bank data. Your Sparkasse Mecklenburg-Schwerin balances and transactions are decrypted locally with a key only you hold — the servers only ever see ciphertext and your public key.

Both business and personal accounts (BIC NOLADE21LWL) are supported, and a single approval keeps data flowing for up to 180 days before you re-confirm.

How to connect Sparkasse Mecklenburg-Schwerin

Connecting happens entirely inside 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 keys are generated right on your device.
  2. In the dashboard, pick Sparkasse Mecklenburg-Schwerin and choose the account type (business or personal).
  3. You are redirected to Sparkasse Mecklenburg-Schwerin's own secure login to approve access under PSD2.
  4. Once you confirm the consent, your accounts sync back into the dashboard automatically.

Because you approve directly on the bank's screen, your credentials are never seen or stored by open-banking.io.

Access your data

After your Sparkasse Mecklenburg-Schwerin connection is live, developers can optionally read it programmatically. On 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. The CLI and SDK only read and sync existing connections — they cannot create one. An API key on its own returns nothing but ciphertext without your private key.

All of this runs for roughly EUR 3/month.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free — no QWAC or PSD2 licence is needed to access your own Sparkasse Mecklenburg-Schwerin data.

Can open-banking.io see my transactions?

No. It is zero-knowledge: data is encrypted with keys held only on your device, so the servers store just your public key and ciphertext.

Up to 180 days per approval, after which you re-confirm access on Sparkasse Mecklenburg-Schwerin's own login screen.
