Kreissparkasse Weilburg API Access & Open Banking

Pulling balances and transactions out of your Kreissparkasse Weilburg accounts usually means screen-scraping or a bank-specific PSD2 portal. open-banking.io removes that friction: it links Kreissparkasse Weilburg (BIC HELADEF1WEI) through a single, standards-based consent, then makes both business and personal accounts available in one dashboard — and, if you write code, one API.

Because the service is zero-knowledge and certificate-free, your financial data is encrypted on your own device with a key only you hold. open-banking.io's servers store just your public key, so they can never read or decrypt what flows through them. That covers over 2,600 EU/UK banks for around EUR 3/month.

How to connect Kreissparkasse Weilburg

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 your encryption passphrase. Your keys are generated locally on your device.
  2. In the dashboard, search for and select Kreissparkasse Weilburg, then choose the account type you need — business or personal.
  3. You are redirected to Kreissparkasse Weilburg's own secure login, where you approve access under PSD2. Consent lasts up to 180 days, after which you simply re-approve.
  4. Your accounts sync back into the dashboard, ready to view or export.

Access your data

Reading Kreissparkasse Weilburg data programmatically is an optional developer step that comes after connecting. Open the Developers page, create an API key, and export a credentials.json that bundles the 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 the X-Api-Key header, and every response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, the data stays unreadable. Note that the CLI and SDK read and sync existing connections; the connection itself is always made in the dashboard.

Does open-banking.io see my Kreissparkasse Weilburg data?

No. Encryption and decryption happen on your device. The service holds only your public key, so it stores ciphertext it cannot read.

Can I connect both business and personal accounts?

Yes. Kreissparkasse Weilburg supports both account types; pick the one you want when selecting the bank, and repeat to add the other.

How long does access last before I re-authorise?

PSD2 consent runs for up to 180 days. When it expires, re-approve on Kreissparkasse Weilburg's login screen to keep syncing.
