Raiffeisenbank Wesermarsch-Süd Open Banking & API

Reach your Raiffeisenbank Wesermarsch-Süd accounts through a single, privacy-first dashboard. open-banking.io links to this Lower Saxony cooperative bank (BIC GENODEF1BRN) under PSD2, covering both business and personal accounts, so you can watch balances and transactions without juggling separate portals. It sits alongside 2,600+ other EU and UK banks, and because the service is certificate-free you never wrangle eIDAS certificates or bank sandboxes.

The defining trait is that it is zero-knowledge. Your data is encrypted with a key generated on your own device and decrypted locally — open-banking.io's servers only ever hold your public key, so they cannot read a single balance.

How to connect Raiffeisenbank Wesermarsch-Süd

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

  1. Sign up for an open-banking.io account.
  2. Set an encryption passphrase; your private keys are created right there on your device.
  3. In the dashboard, choose Raiffeisenbank Wesermarsch-Süd and pick the account type (business or personal).
  4. You are redirected to Raiffeisenbank Wesermarsch-Süd's own secure login to approve access on the bank's consent screen.
  5. Your approved accounts then sync back into your dashboard.

That PSD2 consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Once a 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 own key. The API key alone returns only ciphertext; without your private key, nobody — not even open-banking.io — can read it. The CLI and SDK only read and sync connections that already exist; they never create one.
