Bankhaus RSA Open Banking & API Access | open-banking.io

Reach your Bankhaus RSA accounts through a single, privacy-first workspace. open-banking.io links the Rechtmehring cooperative bank (BIC GENODEF1RME) into a dashboard where balances and transactions land ready to read — and, when you want them, ready to pull programmatically. It covers business and personal accounts, and because it is certificate-free you never touch eIDAS certificates or QWAC provisioning to get started.

What makes it different is the trust model. open-banking.io is zero-knowledge: the encryption keys are generated on your own device and the servers only ever hold your public key. Every balance and payment record is decrypted locally, so no one — not even open-banking.io — can read your Bankhaus RSA data on your behalf.

How to connect Bankhaus RSA

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 open-banking.io and set your encryption passphrase. Your private key is created right there on your device.
  2. In the dashboard, search for Bankhaus RSA and choose the account type you hold — business or personal.
  3. You are redirected to Bankhaus RSA's own secure login, where you approve access under PSD2 consent. Your credentials stay with the bank.
  4. Your accounts sync back into the dashboard, and you can review balances and transactions immediately.

The PSD2 consent you grant lasts up to 180 days, after which you simply re-approve on the bank's screen to keep the connection live.

Access your data

Once Bankhaus RSA is connected, developers can optionally read the data in code. 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. An API key on its own only returns ciphertext — without your private key there is nothing readable to see. The CLI and SDK read and sync existing connections; they never create one.

All of this runs for around EUR 3/month, across 2,600+ supported EU and UK banks.

Do I need a certificate or developer account to start?

No. Connecting Bankhaus RSA is a dashboard flow — sign up, set a passphrase, approve on the bank's screen. API keys are only for the optional developer step.

Can open-banking.io see my Bankhaus RSA transactions?

No. The service is zero-knowledge and holds only your public key. Your data is decrypted on your device with a key only you possess.

How long does access to Bankhaus RSA last?

Each PSD2 consent runs up to 180 days. When it expires, re-approve on Bankhaus RSA's login screen to continue syncing.
