Sparkasse Burbach-Neunkirchen API & Open Banking Access

Sparkasse Burbach-Neunkirchen serves the Siegerland region of North Rhine-Westphalia, and its business and personal account holders can bring that data into their own tools through open-banking.io. Instead of scraping statements or wrangling certificates, you authorise read access once and let your balances and transaction history sync into a private dashboard. open-banking.io covers 2,600+ EU and UK banks, and it is zero-knowledge by design: your account data is decrypted on your own device with a key that never leaves it. The bank is identified by BIC WELADED1BUB.

How to connect Sparkasse Burbach-Neunkirchen

Connecting happens entirely in 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 an encryption passphrase. Your key pair is generated locally on your device, so only you can later unlock the data.
  2. In the dashboard, search for Sparkasse Burbach-Neunkirchen and choose your account type — business or personal.
  3. You are redirected to Sparkasse Burbach-Neunkirchen's own secure login, where you approve access under PSD2. Consent lasts up to 180 days before you renew it.
  4. Your accounts sync back into the dashboard, ready to view.

That is the whole flow — you approve on the bank's screen, and nothing about your credentials ever touches open-banking.io.

Access your data

Programmatic access is an optional step after the connection exists. On 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 you can 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 and sync connections you already made in the dashboard — they cannot connect a bank themselves.

Because open-banking.io holds only your public key, its servers never see readable data. It is certificate-free, and access runs about EUR 3/month.

Does open-banking.io ever see my transactions?

No. Data is encrypted to your key and decrypted on your device. The service stores ciphertext it cannot read.

Can I connect using only an API key?

No. An API key alone returns ciphertext. Readable data requires the private key inside your credentials.json.

How long does access last before renewal?

Sparkasse Burbach-Neunkirchen consent is valid for up to 180 days, after which you re-approve on the bank's login screen.
