Sparkasse Oberpfalz Nord API Access & Open Banking

Reaching account data at Sparkasse Oberpfalz Nord (BIC BYLADEM1WEN) usually means wrestling with PSD2 certificates and bank-specific sandboxes. open-banking.io removes that friction. It links to Sparkasse Oberpfalz Nord on your behalf and hands you a clean, unified view of your balances and transactions — for both business and personal accounts — without a single certificate to provision.

The service is zero-knowledge by design. Your bank data is encrypted and decrypted locally with a key that never leaves your device, so open-banking.io only ever holds your public key. You get the convenience of aggregated access with none of the usual trust trade-offs.

How to connect Sparkasse Oberpfalz Nord

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 an open-banking.io account.
  2. Set your encryption passphrase. Your keys are generated right there on your own device.
  3. In the dashboard, pick Sparkasse Oberpfalz Nord and choose your account type — business or personal.
  4. You are redirected to Sparkasse Oberpfalz Nord's own secure login, where you approve access on the bank's official PSD2 consent screen.
  5. Your accounts sync back into the dashboard, ready to view.

Consent lasts up to 180 days, the maximum Sparkasse Oberpfalz Nord permits, after which you simply re-approve to keep the connection live.

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 directly.

Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, the data stays unreadable, even to open-banking.io. The CLI and SDK read and sync connections you already made in the dashboard; they never establish new ones.

All of this runs for around EUR 3/month.
