Stadtsparkasse Schwerte Open Banking & API Access

Reaching your Stadtsparkasse Schwerte account data no longer means wrestling with eIDAS certificates or a bank sandbox. open-banking.io gives you a single, tidy path to your Schwerte balances and transactions — covering both business and personal accounts — while keeping the encryption keys entirely on your own device. The bank (BIC WELADED1SWT) is one of 2,600+ institutions reachable through the same dashboard, so a Schwerte connection behaves exactly like every other bank you add.

Because open-banking.io is zero-knowledge, its servers only ever hold your public key. Every figure that lands in your dashboard is decrypted locally, so nobody at open-banking.io — or anywhere else — can read your Stadtsparkasse Schwerte statements.

How to connect Stadtsparkasse Schwerte

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 open-banking.io and set your encryption passphrase. Your key pair is generated right there on your device.
2. In the dashboard, search for Stadtsparkasse Schwerte and choose the account type you need — business or personal.
3. You are redirected to Stadtsparkasse Schwerte's own secure login, where you approve access under PSD2. A single consent lasts up to 180 days before you renew it.
4. Your approved accounts sync back into the dashboard, ready to view.

That's the whole flow — you approve access on the bank's screen, never by handing credentials to anyone else.

Access your data

Once a Schwerte connection is live, reading it programmatically is an optional developer step. On the Developers page, create an API key and export a credentials.json — it bundles that API key with your private decryption key. From there the CLI (openbanking accounts, openbanking transactions, openbanking sync), the SDKs, and the REST API all work against your existing connections. Requests carry your key in the X-Api-Key header, and each response is decrypted locally with your private key. An API key on its own only ever returns ciphertext — the readable numbers appear solely on your machine. Note the tooling only reads and syncs connections; there is no connect command.

All of this runs for roughly EUR 3/month, with no certificate paperwork.

Does open-banking.io see my Stadtsparkasse Schwerte data?

No. It stores only your public key; decryption happens on your device, so the service never sees readable data.

Which account types can I link?

Both business and personal Stadtsparkasse Schwerte accounts are supported through the standard PSD2 consent.

How often do I re-approve?

A Schwerte consent is valid for up to 180 days; after that you simply repeat the approval on the bank's login screen.
