Rheingauer Volksbank API Access & Open Banking

Reaching your Rheingauer Volksbank accounts programmatically usually means wrestling with eIDAS certificates and PSD2 sandboxes. open-banking.io removes that hurdle. It links the Geisenheim-based cooperative bank (BIC GENODE51RGG) to a single dashboard and, optionally, a developer API — without you ever holding a QWAC certificate or handing your data to a third party in the clear. Everything is decrypted locally with a key only you possess.

Rheingauer Volksbank supports both business and personal accounts, and a single consent stays valid for up to 180 days before the bank asks you to re-authorise.

How to connect Rheingauer Volksbank

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 key pair is generated on your own device, so only you can read what comes back.
  2. In the dashboard, search for Rheingauer Volksbank and choose whether you're linking a business or personal account.
  3. You're redirected to Rheingauer Volksbank's own secure login, where you approve access on the bank's PSD2 consent screen — your credentials go only to the bank.
  4. Once approved, your accounts and transactions sync into your dashboard automatically.

Access your data

After a connection exists, developers can optionally read it 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your key. The CLI and SDK only read and sync existing connections — they never create one.

Because open-banking.io is zero-knowledge, its servers store only your public key and can never decrypt your data. All of this runs for roughly EUR 3/month, with no certificate paperwork.

Is a QWAC or eIDAS certificate required?

No. open-banking.io handles the regulated PSD2 layer, so you connect Rheingauer Volksbank without any certificate of your own.

Yes. Rheingauer Volksbank offers both account types, and you can connect each from the dashboard as a separate consent.

Does an API key alone return readable data?

No. Without your private decryption key you receive only ciphertext — readable data requires the key held solely in your credentials.json.
