Sparkasse Dillenburg Open Banking & API Access

Pulling your Sparkasse Dillenburg balances and transactions into your own tools no longer means wrestling with bank contracts or eIDAS certificates. open-banking.io gives you PSD2-grade access to Sparkasse Dillenburg (BIC HELADEF1DIL) through one dashboard, covering both business and personal accounts. Everything you sync is encrypted on your own device with a key only you hold, so the service itself never sees your statements in the clear.

How to connect Sparkasse Dillenburg

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 an encryption passphrase. Your keys are generated locally on your device, never on our servers.
  3. In the dashboard, search for Sparkasse Dillenburg and choose the account type you need — business or personal.
  4. You are redirected to Sparkasse Dillenburg's own secure login, where you approve access on the bank's PSD2 consent screen.
  5. Your accounts sync straight back into the dashboard, ready to view.

Consent lasts up to 180 days, the regulatory maximum, after which you simply re-approve on the bank's screen to keep the connection live.

Access your data

Once the connection exists, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json bundle — this holds your API key plus 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. Note that the CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command.

Because open-banking.io is zero-knowledge, our servers store only your public key. An API key on its own returns ciphertext; without your private key it stays unreadable. No bank certificate is ever required, and the whole thing runs at around EUR 3/month.

Does Sparkasse Dillenburg support business accounts?

Yes. Both business and personal Sparkasse Dillenburg accounts can be connected and synced.

Up to 180 days per approval. Renew by re-authorising on Sparkasse Dillenburg's consent screen.

Can open-banking.io read my Sparkasse Dillenburg data?

No. Data is decrypted only on your device with a key we never hold, so we cannot read it.
