Stadtsparkasse Schwelm Open Banking & API Access

Want a single, secure way to reach your Stadtsparkasse Schwelm accounts? open-banking.io lets you link this Bergisches-Land Sparkasse and read balances and transactions without certificates, screen-scraping, or eIDAS paperwork. Stadtsparkasse Schwelm covers both business and personal accounts (BIC WELADED1SLM), and every consent stays valid for up to 180 days before you renew it. Because open-banking.io is zero-knowledge, your data is decrypted on your own device with a key only you hold.

How to connect Stadtsparkasse Schwelm

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 your encryption passphrase. Your keys are generated locally on your device, so the service never sees them.
  2. In the dashboard, pick Stadtsparkasse Schwelm from the bank list and choose the account type you need — business or personal.
  3. You are redirected to Stadtsparkasse Schwelm's own secure login, where you approve access under PSD2 (the standard bank consent screen).
  4. Once approved, your accounts sync back into your open-banking.io dashboard, ready to view.

That's the whole flow — approval always takes place on the bank's site, never through open-banking.io.

Access your data

After 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. Then 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 or sync connections that already exist; there is no connect command. An API key on its own returns ciphertext — without your private key, nobody, including open-banking.io's servers, can read it.

All of this runs for about EUR 3 per month across 2,600+ supported EU and UK banks.

Is a certificate or eIDAS license required?

No. open-banking.io is certificate-free. You approve access directly on Stadtsparkasse Schwelm's consent screen — no QWAC or developer registration needed.

How long does access to Stadtsparkasse Schwelm last?

Up to 180 days per consent. When it expires, simply re-approve on the bank's login to continue syncing.

Can open-banking.io read my Stadtsparkasse Schwelm data?

No. The service is zero-knowledge and holds only your public key. Data is decrypted locally with the private key that never leaves your device.
