Sparkasse Ennepetal-Breckerfeld API & Open Banking Access

Reading account data from Sparkasse Ennepetal-Breckerfeld no longer means wrestling with PSD2 certificates or corporate onboarding. open-banking.io gives you a single, private route to your balances and transactions — covering both business and personal accounts held under BIC WELADED1ENE — while keeping the decryption key exclusively on your own device.

The service spans 2,600+ EU and UK banks. What makes it different is the trust model: it is zero-knowledge. Data is encrypted end to end and decrypted locally with a key only you hold. The open-banking.io servers store nothing but your public key, so they can never read your Sparkasse Ennepetal-Breckerfeld statements — and there are no eIDAS certificates to buy or renew.

How to connect Sparkasse Ennepetal-Breckerfeld

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 key pair is generated right there on your device.
  3. In the dashboard, search for Sparkasse Ennepetal-Breckerfeld and choose the account type — business or personal.
  4. You are redirected to Sparkasse Ennepetal-Breckerfeld's own secure login, where you approve access on the bank's PSD2 consent screen.
  5. Your accounts sync back into the dashboard, ready to view.

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

Access your data

Once a connection exists, developers can optionally read it programmatically. Open 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 API key alone only ever returns ciphertext — without your private key the data stays unreadable, even to you until it is decrypted on your machine. The CLI and SDK read and refresh existing connections; they never create one.

All of this runs for roughly EUR 3/month.

Can open-banking.io see my Sparkasse Ennepetal-Breckerfeld transactions?

No. It is zero-knowledge — the servers hold only your public key, so decryption only ever happens on your device.

Do I need a PSD2 certificate?

No. The service is certificate-free; you approve access directly on Sparkasse Ennepetal-Breckerfeld's consent screen.

Can I connect the account from the CLI?

No. Connecting is a dashboard-only step. The CLI and SDK only read or sync connections you have already approved.
