Stadtsparkasse Rahden API Access & Open Banking

Reaching Stadtsparkasse Rahden account data no longer means wrestling with eIDAS certificates or bank sandboxes. open-banking.io gives you a single, PSD2-compliant path to your balances and transactions — and because every payload is decrypted on your own device, the platform never sees a readable byte. Stadtsparkasse Rahden (BIC WELADED1RHD) is one of 2,600+ EU and UK institutions you can link, covering both business and personal accounts.

How to connect Stadtsparkasse Rahden

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

  1. Sign up for open-banking.io and set an encryption passphrase. Your keys are generated locally on your device, so only you ever hold the private key.
  2. In the dashboard, search for and select Stadtsparkasse Rahden, then choose the account type you need — business or personal.
  3. You are redirected to Stadtsparkasse Rahden's own secure login, where you approve access on the bank's PSD2 consent screen. Consent lasts up to 180 days before you renew it.
  4. Your approved accounts sync straight into your dashboard, ready to view.

Access your data

Developers can optionally read the same data programmatically, but only after the connection above exists. Open the Developers page, create an API key, and export a credentials.json — this bundles your 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. Requests carry your key in the X-Api-Key header, and each response is decrypted locally with your own key. Without that private key, an API key alone returns only ciphertext — the servers hold nothing but your public key.

The service is certificate-free and zero-knowledge, and costs around EUR 3/month.

Does open-banking.io work with business accounts at Stadtsparkasse Rahden?
