Raiffeisenbank HessenNord API & Open Banking Access

Raiffeisenbank HessenNord eG is a cooperative bank serving northern Hesse from Wolfhagen, and its business and personal accounts can be reached through open-banking.io using regulated PSD2 access. Instead of chasing eIDAS certificates or bank-specific sandboxes, you link the bank once and then read balances and transactions on your own terms. Everything that arrives in your account is encrypted, and only you hold the key that turns it back into readable data.

open-banking.io is certificate-free and zero-knowledge: the platform stores only your public key, so its servers can never see inside your Raiffeisenbank HessenNord data. With coverage of 2,600+ EU and UK banks for roughly EUR 3/month, it replaces a stack of compliance paperwork with a single subscription.

How to connect Raiffeisenbank HessenNord

Connecting happens entirely in 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 own device, so the decryption key never leaves you.
  2. In the dashboard, search for Raiffeisenbank HessenNord (BIC GENODEF1WOH) and choose the account type you need — business or personal.
  3. You are redirected to Raiffeisenbank HessenNord's own secure login and consent screen, where you approve access directly with the bank.
  4. Your approved accounts sync back into the dashboard. The consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Once the connection exists, developers can optionally read it programmatically. 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 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 key. The CLI and SDK only read and sync connections you already approved — they never create one, and an API key alone returns nothing but ciphertext.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free — the platform handles regulated access, so you never register your own PSD2 certificate.
