Kieler Volksbank API Access & Open Banking Data

Reaching Kieler Volksbank account data used to mean wrestling with PSD2 certificates, sandboxes and per-bank paperwork. open-banking.io removes all of that. It gives you a single, privacy-first path to your Kieler Volksbank business or personal accounts (BIC GENODEF1KIL), with every figure decrypted on your own device using a key that never leaves it. No eIDAS certificate, no bank-specific onboarding — just a clean, certificate-free bridge to a cooperative bank in Kiel and 2,600+ others across the EU and UK.

How to connect Kieler Volksbank

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 keys are generated locally, on your device, so only you can later unlock the data.
  2. In the dashboard, search for Kieler Volksbank and choose the account type you need — business or personal.
  3. You are redirected to Kieler Volksbank's own secure login, where you approve access on the bank's PSD2 consent screen. That consent lasts up to 180 days before a quick re-approval is needed.
  4. Your approved accounts then sync straight into your open-banking.io dashboard, ready to view.

Access your data

Programmatic access is an optional step you can take after the bank is connected. From the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. With it you can run the CLI (openbanking accounts, openbanking transactions, openbanking sync), or call the SDK and REST API. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. Note the CLI and SDK only read or sync connections you already approved — they never establish one. And because open-banking.io is zero-knowledge, its servers hold only your public key; an API key on its own returns ciphertext, never readable data. All of this runs for around EUR 3/month.
