Volksbank Senden API Access & Open Banking Data

Reaching Volksbank Senden account data used to mean eIDAS certificates, sandbox registrations and a compliance backlog. open-banking.io removes all of that. It is a certificate-free, zero-knowledge gateway to 2,600+ EU and UK banks, and Volksbank Senden (BIC GENODEM1SDN) is one of them. Both business and personal accounts are supported, and every consent runs for up to 180 days before you renew it.

The distinguishing feature is where decryption happens. Your encryption keys are generated on your own device, so open-banking.io only ever holds your public key. Balances and transactions are unreadable to the service itself — they are decrypted locally, by you, with a key nobody else has.

How to connect Volksbank Senden

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 open the web dashboard.
  2. Set your encryption passphrase. This generates your key pair locally; the private half never leaves your device.
  3. In the dashboard, search for and select Volksbank Senden, then choose the account type — business or personal.
  4. You are redirected to Volksbank Senden's own secure login, where you approve access under PSD2 (valid up to 180 days).
  5. Once approved, your accounts sync straight into your dashboard.

That is the whole flow. You authenticate on the bank's screen, not ours, and consent stays between you and Volksbank Senden.

Access your data

Programmatic access is an optional step for developers, and only after a connection already exists. 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 directly.

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 — the readable data appears solely on your machine. Note that the CLI and SDK read and sync existing connections; they never create one.

All of this runs at roughly EUR 3/month.
