Sparda-Bank West API Access & Open Banking Data

Sparda-Bank West is a member-owned cooperative bank serving North Rhine-Westphalia, and its accounts fall under PSD2 — meaning you have a right to your own banking data. open-banking.io turns that right into something usable: a single dashboard where your Sparda-Bank West balances and transactions arrive already decrypted with a key that never leaves your device.

There are no eIDAS certificates to register, no bank-by-bank paperwork, and no servers that can read your finances. open-banking.io is zero-knowledge by design: it stores only your public key, so everything it holds about your Sparda-Bank West accounts stays ciphertext until it reaches you. Sparda-Bank West (BIC GENODED1SPK) supports both business and personal accounts, and a single approval keeps data flowing for up to 180 days before you renew.

How to connect Sparda-Bank West

Connecting happens entirely inside the open-banking.io dashboard — no code, no API call:

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally on your device at this moment.
  2. In the dashboard, search for Sparda-Bank West and choose the account type you hold (business or personal).
  3. You are redirected to Sparda-Bank West's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Control returns to your dashboard and your accounts sync automatically.

Because approval takes place on Sparda-Bank West's own systems, open-banking.io never sees your banking credentials.

Access your data

Reading Sparda-Bank West data programmatically is an optional step for developers, and only after the connection above exists. Open 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 use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Calls send your key in the X-Api-Key header, and every response is decrypted locally with your private key. The CLI and SDK only read and sync connections you already made — they cannot create one.

Can I connect Sparda-Bank West with an API key?

No. Connecting is a dashboard action with consent on Sparda-Bank West's site. API keys only read data that is already linked.

What does it cost?

Around EUR 3 per month for full access across 2,600+ supported banks.

Can open-banking.io staff see my transactions?

No. They hold only your public key, so stored data is ciphertext they cannot decrypt.
