Volksbank Halle/Westf. API Access & Open Banking

Reaching your Volksbank Halle/Westf. accounts programmatically usually means bank certificates, an eIDAS setup and a PSD2 licence. open-banking.io removes all of that. It is a certificate-free, zero-knowledge gateway covering 2,600+ EU and UK banks, including Volksbank Halle/Westf. eG (BIC GENODEM1HLW), the cooperative bank based in Halle (Westfalen). You link both business and personal accounts, and every figure that lands in your dashboard is decrypted on your own device with a key nobody else — not even open-banking.io — can reproduce.

How to connect Volksbank Halle/Westf.

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, endpoint or key involved in this step:

  1. Sign up for open-banking.io and set an encryption passphrase. Your key pair is generated locally, so only your public key ever leaves your machine.
  2. In the dashboard, choose Volksbank Halle/Westf. and select whether you are linking a business or personal account.
  3. You are redirected to Volksbank Halle/Westf.'s own secure login, where you approve access under PSD2. Your credentials go only to the bank.
  4. Once approved, your accounts and transactions sync straight into your dashboard. The consent stays valid for up to 180 days, after which you simply re-approve.

Access your data

Want the data in code? That is an optional step you take after the connection exists. Open the Developers page, create an API key and export a credentials.json bundling that key with your private decryption key. From there the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK or the REST API return everything. Requests authenticate with the X-Api-Key header, and each response is decrypted locally with your own key. The CLI and SDK only read and sync connections that already exist — they never establish one. And an API key on its own yields only ciphertext: without your private key there is nothing readable to see.

Pricing is a flat ~EUR 3/month, with no per-call fees or certificate costs.

Is my Volksbank Halle/Westf. login shared with open-banking.io?

No. You authenticate only on the bank's own consent screen. open-banking.io never sees your banking password.

Can open-banking.io read my account data?

No. The service is zero-knowledge and holds only your public key. Decryption happens on your device.

No. Connecting is done in the dashboard. API keys and credentials.json are only for optional programmatic access afterwards.
