Raiffeisenbank Kastellaun Open Banking & API Access

Raiffeisenbank Kastellaun (BIC GENODED1KSL) is a cooperative bank serving the Hunsrück region of Rhineland-Palatinate. With open-banking.io you can reach both business and personal accounts held there through a single PSD2-compliant service — no eIDAS certificate, no bank-specific integration work, and no data ever leaving your control in readable form. Everything you retrieve is decrypted locally with a key that only you hold.

Because open-banking.io is zero-knowledge, its servers store only your public key. Balances, transactions and account details stay encrypted end to end, so even the service operator cannot read what syncs through it.

How to connect Raiffeisenbank Kastellaun

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 an open-banking.io account.
  2. Set an encryption passphrase. Your keys are generated on your own device, so the passphrase never reaches our servers.
  3. In the dashboard, pick Raiffeisenbank Kastellaun and choose the account type (business or personal).
  4. You are redirected to Raiffeisenbank Kastellaun's own secure login to approve access on their consent screen.
  5. Once approved, your accounts sync into your dashboard automatically.

Consent lasts up to 180 days, after which you simply re-approve on the bank's screen to keep the connection live.

Access your data

Reading data programmatically is an optional step that comes after the bank is connected. From the Developers page, create an API key and export a credentials.json — this file bundles the API key together with your private decryption key. You can 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. An API key alone only ever returns ciphertext — without your private key the data stays unreadable, which is exactly how zero-knowledge is enforced. Note the CLI and SDK only read and sync connections that already exist; there is no connect command.

All of this runs for roughly EUR 3/month.

Do I need a certificate to access Raiffeisenbank Kastellaun?

No. open-banking.io is certificate-free — you connect through the dashboard and approve access on the bank's own login page.

Can open-banking.io read my Raiffeisenbank Kastellaun data?

No. It holds only your public key. Data is decrypted on your device with a key only you have.

How long does access last?
