Raiffeisenbank Welling Open Banking & API Access

open-banking.io gives you a private, unified way to reach your Raiffeisenbank Welling accounts (BIC GENODED1WLG) without wrestling with bank certificates or PSD2 paperwork. It works for both business and personal account holders, and every piece of data that lands in your dashboard is decrypted on your own device with a key that never leaves it. The service itself is zero-knowledge: its servers only ever hold your public key, so they cannot read your balances or transactions.

How to connect Raiffeisenbank Welling

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 an open-banking.io account.
  2. Set your encryption passphrase. Your key pair is generated locally in your browser, so only you can later unlock your data.
  3. In the dashboard, search for Raiffeisenbank Welling and choose the account type you hold — business or personal.
  4. You are redirected to Raiffeisenbank Welling's own secure login, where you approve access on the bank's consent screen (standard PSD2). A single consent stays valid for up to 180 days before you renew it.
  5. Your selected accounts sync back into your dashboard, ready to view.

Access your data

Once a connection exists, reading it programmatically is an optional developer step. On 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 you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and each response is decrypted locally with your own key. An API key on its own only returns ciphertext, so nobody but you can turn it into readable data. Note that the CLI and SDK only read or sync connections you already made in the dashboard — they never establish the bank link themselves.

At roughly EUR 3 per month, you get certificate-free access and privacy by design.

Does open-banking.io see my Raiffeisenbank Welling data?

No. It is zero-knowledge — it stores only your public key, and decryption happens on your device.

Can I connect using only an API key?

No. Connecting is done in the dashboard via Raiffeisenbank Welling's own consent screen; API keys are for reading data afterward.

Up to 180 days, after which you re-approve access on the bank's login page.
