Stadtsparkasse Solingen API Access & Open Banking
Pulling account and transaction data from Stadtsparkasse Solingen no longer means chasing eIDAS certificates or building a PSD2 stack from scratch. open-banking.io gives you a single, certificate-free path to the Solingen Sparkasse (BIC SOLSDE33XXX), covering both business and personal accounts. Everything you retrieve is decrypted locally with a key that only you hold — the service is zero-knowledge and never sees your statements in the clear.
How to connect Stadtsparkasse Solingen
Connecting happens entirely in the open-banking.io dashboard — there is no API call, code, or key involved in this step:
- Sign up for open-banking.io and set your encryption passphrase. Your keys are generated on your own device, so nobody else can reconstruct them.
- In the dashboard, pick Stadtsparkasse Solingen and choose the account type (business or personal).
- You are redirected to Stadtsparkasse Solingen's own secure login, where you approve access under PSD2 consent — valid for up to 180 days before you renew.
- Your approved accounts sync straight into your dashboard, ready to view.
Because you authorise directly on the bank's screen, your Solingen credentials are never shared with open-banking.io.
Access your data
Want the data programmatically? That's an optional developer step after connecting. 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. An API key alone only ever returns ciphertext — without your private key it's unreadable, which is exactly what zero-knowledge means.
All of this runs at around EUR 3/month, with no certificate paperwork and no per-bank onboarding.
Does open-banking.io store my Stadtsparkasse Solingen login?
No. You authenticate on Stadtsparkasse Solingen's own consent screen, and open-banking.io holds only your public key — never your banking password or plaintext data.
How long does access last?
Stadtsparkasse Solingen consent lasts up to 180 days. When it expires, simply re-approve from the dashboard to keep your business or personal accounts syncing.
Do I need the CLI to connect?
No. Connecting is done in the dashboard. The CLI, SDK, and REST API only read and sync connections you have already made — there is no connect command.
