Sparkasse Freiburg-Nördlicher Breisgau API & Open Banking

Pulling account and transaction data out of Sparkasse Freiburg-Nördlicher Breisgau (BIC FRSPDE66XXX) usually means wrestling with PSD2 certificates and bank sandboxes. open-banking.io removes that overhead: a certificate-free, zero-knowledge service that links your Baden-Württemberg Sparkasse and syncs both business and personal accounts into one dashboard — decrypted only on your own device.

How to connect Sparkasse Freiburg-Nördlicher Breisgau

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

  1. Sign up at open-banking.io and set your encryption passphrase. Your keys are generated locally on your device, so only you ever hold the private decryption key.
  2. In the dashboard, pick Sparkasse Freiburg-Nördlicher Breisgau and choose the account type — business or personal.
  3. You are redirected to Sparkasse Freiburg-Nördlicher Breisgau's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve.

Access your data

Reading the data programmatically is an optional developer step that comes after the connection exists. From the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. Then use the CLI:

openbanking accounts
openbanking transactions
openbanking sync

The same works through the SDK or 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 created in the dashboard — they never establish the bank link themselves.

Because open-banking.io is zero-knowledge, its servers store only your public key and can never read or decrypt your Sparkasse Freiburg-Nördlicher Breisgau data. An API key alone returns only ciphertext without your private key. All of this runs at roughly EUR 3/month, with no eIDAS certificates to procure.

Is a PSD2 certificate required?

No. open-banking.io is certificate-free — you authorize access directly on Sparkasse Freiburg-Nördlicher Breisgau's consent screen.

Can I connect a business account?

Yes. Both business and personal Sparkasse Freiburg-Nördlicher Breisgau accounts are supported; pick the type when you connect.

How long does access last before renewal?

Up to 180 days per consent, the PSD2 maximum, after which you re-approve in the dashboard.
