Access GENO BANK ESSEN Data — Open Banking API

Pulling live balances and transactions from GENO BANK ESSEN no longer means chasing a PSD2 licence or juggling eIDAS certificates. open-banking.io gives you a single, certificate-free path to your GENO BANK ESSEN accounts (BIC GENODEM1GBE), covering both business and personal account types. Everything you retrieve is encrypted end-to-end and decrypted on your own device with a key only you hold — our servers store only your public key and never see your banking data in the clear.

How to connect GENO BANK ESSEN

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key involved in linking your bank:

  1. Sign up for open-banking.io and open the web dashboard.
  2. Set an encryption passphrase. Your key pair is generated locally on your device from this passphrase, so the private key never leaves your machine.
  3. Pick GENO BANK ESSEN in the dashboard and choose the account type — business or personal.
  4. Approve on GENO BANK ESSEN's own login. You are redirected to the bank's secure PSD2 consent screen, where you authenticate directly with GENO BANK ESSEN and grant access.
  5. Your accounts sync back into the dashboard. A single consent stays valid for up to 180 days before GENO BANK ESSEN requires you to re-approve.

Access your data

Once the connection is live, reading it programmatically is an optional developer step. From the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. 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 on its own only ever returns ciphertext — without your private key it stays unreadable, which is what makes the service genuinely zero-knowledge.

At roughly EUR 3/month, you skip the compliance overhead entirely while keeping full custody of your data.
