Sparkasse Landsberg-Dießen API Access & Open Banking

Reaching your Sparkasse Landsberg-Dießen accounts programmatically no longer means wrestling with bank sandboxes, eIDAS certificates or PSD2 registration. open-banking.io gives you a single, certificate-free path to your Landsberg am Lech and Ammersee-region accounts — covering both business and personal products under BIC BYLADEM1LLD — while keeping the data encrypted so only you can read it.

The service spans 2,600+ EU and UK banks and is built around a zero-knowledge design: your encryption keys are generated on your own device, and open-banking.io's servers only ever hold your public key. Balances and transactions are decrypted locally, never in the cloud.

How to connect Sparkasse Landsberg-Dießen

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

  1. Sign up at open-banking.io and set your encryption passphrase. This generates your personal key pair locally; the passphrase never leaves your device.
  2. In the dashboard, search for and select Sparkasse Landsberg-Dießen, then choose the account type you need — business or personal.
  3. You are redirected to Sparkasse Landsberg-Dießen's own secure login, where you approve access on the bank's PSD2 consent screen. Consent lasts up to 180 days before a renewal is needed.
  4. Your approved accounts sync straight into your dashboard, ready to view.

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. 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 connections you already approved in the dashboard — there is no connect command.

All of this runs for roughly EUR 3/month, with no per-call fees and no certificate paperwork.

Do I need an eIDAS certificate?

No. open-banking.io handles the regulated PSD2 layer, so you never register with the bank or hold a certificate.

Can open-banking.io see my Sparkasse Landsberg-Dießen data?

No. It stores only your public key; decryption happens on your device with a private key only you hold.

Does an API key alone return my transactions?

No. Without your private decryption key you receive only ciphertext — readable data requires the key in your credentials.json.
