Sparkasse Dillingen-Nördlingen API Access & Open Banking

Pulling your Sparkasse Dillingen-Nördlingen balances and transactions into your own tools no longer means chasing a PSD2 licence or juggling eIDAS certificates. open-banking.io gives you PSD2 access to Sparkasse Dillingen-Nördlingen (BIC BYLADEM1DLG) for both business and personal accounts, and does it with a zero-knowledge design: your bank data is decrypted locally with a key only you hold, so the service itself only ever stores your public key.

How to connect Sparkasse Dillingen-Nördlingen

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

  1. Sign up for an open-banking.io account.
  2. Set an encryption passphrase. Your keys are generated on your own device, so nobody at open-banking.io can read your data.
  3. In the dashboard, pick Sparkasse Dillingen-Nördlingen and choose the account type — business or personal.
  4. You are redirected to Sparkasse Dillingen-Nördlingen's own secure login to approve access on their PSD2 consent screen.
  5. Your accounts sync back into the dashboard. Consent lasts up to 180 days before Sparkasse Dillingen-Nördlingen asks you to re-authorise.

Access your data

Once the connection is live, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this holds the API key plus 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. An API key on its own returns ciphertext; without your private key it stays unreadable.

At roughly EUR 3/month, you get certificate-free, zero-knowledge access across 2,600+ EU and UK banks — Sparkasse Dillingen-Nördlingen included.

Do I need a PSD2 licence or certificate?

No. open-banking.io handles the regulated layer, so no eIDAS certificate or licence is required on your side.

Can open-banking.io read my Sparkasse Dillingen-Nördlingen data?

No. It is zero-knowledge and holds only your public key. Decryption happens on your device with a key only you have.

How long does access last before I re-authorise?

Sparkasse Dillingen-Nördlingen grants consent for up to 180 days, after which you re-approve on the bank's consent screen.
