Sparkasse Mansfeld-Südharz API Access & Open Banking

Reaching your Sparkasse Mansfeld-Südharz account data no longer means wrestling with PSD2 certificates or a bank-run developer portal. open-banking.io gives you a single, private way to view balances and transactions from Sparkasse Mansfeld-Südharz (BIC NOLADE21EIL) across both business and personal accounts. Everything is decrypted on your own device with a key only you hold — the service never sees your statements in the clear.

How to connect Sparkasse Mansfeld-Südharz

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 locally on your device, so nobody else can reconstruct them.
  2. In the dashboard, search for Sparkasse Mansfeld-Südharz and choose the account type you need — business or personal.
  3. You are redirected to Sparkasse Mansfeld-Südharz's own secure login and consent screen, where you approve access directly with the bank (standard PSD2 consent).
  4. Your accounts then sync back into the dashboard. The consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Because the login and approval stay on Sparkasse Mansfeld-Südharz's own domain, your credentials are never shared with open-banking.io.

Access your data

Once a connection exists, 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command.

This is the zero-knowledge, certificate-free design: open-banking.io stores only your public key, so an API key alone returns ciphertext until your private key unlocks it locally. Access to 2,600+ EU/UK banks costs around EUR 3/month.
