Gladbacher Bank von 1922 API & Open Banking Access

Gladbacher Bank von 1922 (BIC GENODED1GBM) is a cooperative bank in Mönchengladbach, and open-banking.io gives you a clean way to reach its account data without the usual PSD2 red tape. There are no eIDAS certificates to buy and no regulatory licence to hold: you link your own business or personal accounts and read them yourself. Every response is decrypted on your device with a key only you possess, so open-banking.io stores only your public key and never sees your balances or statements.

How to connect Gladbacher Bank von 1922

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key at this stage.

  1. Sign up for open-banking.io and set your encryption passphrase. Your key pair is generated locally, on your own device.
  2. In the dashboard, search for Gladbacher Bank von 1922 and choose the account type you want to link — business or personal are both supported.
  3. You are redirected to Gladbacher Bank von 1922's own secure login, where you approve access on the bank's official PSD2 consent screen.
  4. Your approved accounts sync straight back into your dashboard. Consent lasts up to 180 days, after which you simply 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 whichever surface suits you:

  • CLI — openbanking accounts, openbanking transactions, openbanking sync
  • SDK or the REST API, authenticating with the X-Api-Key header

Every payload comes back encrypted and is decrypted locally with your key. The CLI and SDK only read and sync connections that already exist — there is no connect command, because linking a bank always goes through the dashboard flow above. All of this runs on the standard ~EUR 3/month plan.

Does open-banking.io ever see my Gladbacher Bank von 1922 data?

No. It is zero-knowledge — the service holds only your public key, and decryption happens on your device with a private key that never leaves it.

Do I need an API key to connect the bank?

No. Connecting is done in the dashboard by approving access on Gladbacher Bank von 1922's login. API keys only matter later, if you want to read data with the CLI, SDK, or REST API.

What can I do with a business account?

Gladbacher Bank von 1922 supports both business and personal account types, so you can sync company and private accounts through the same dashboard and read them the same way.
