Raiffeisenbank Aichhalden-Hardt-Sulgen API Access & Open Banking

Reaching account data from Raiffeisenbank Aichhalden-Hardt-Sulgen eG no longer means wrestling with eIDAS certificates or a PSD2 sandbox. open-banking.io covers this Baden-Württemberg cooperative bank (BIC GENODES1HAR) alongside 2,600+ other EU and UK institutions, and it links to both business and personal accounts. Everything is built around one principle: your balances and transactions are decrypted only on your own device, with a key that never leaves it.

How to connect Raiffeisenbank Aichhalden-Hardt-Sulgen

Connecting happens entirely inside the open-banking.io dashboard — there is no endpoint to call and no key to paste to establish the link.

  1. Sign up for open-banking.io and set your encryption passphrase. Your key pair is generated locally, so the service only ever holds your public key.
  2. In the dashboard, search for Raiffeisenbank Aichhalden-Hardt-Sulgen and choose the account type you need (business or personal).
  3. You are redirected to Raiffeisenbank Aichhalden-Hardt-Sulgen's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve.

No developer redirects the account holder, and nothing about this step touches an API.

Access your data

Once the connection exists, reading it programmatically is an optional developer add-on. From the Developers page, create an API key and export a credentials.json — this bundles your API key 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 key. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command. An API key on its own returns ciphertext; without your private key, the data stays unreadable.

The result is a certificate-free, zero-knowledge pipeline for Raiffeisenbank Aichhalden-Hardt-Sulgen data, for roughly EUR 3/month.

Do I need a PSD2 certificate for Raiffeisenbank Aichhalden-Hardt-Sulgen?

No. open-banking.io handles the regulated connection; you just approve consent on the bank's own screen.

Can open-banking.io read my Raiffeisenbank Aichhalden-Hardt-Sulgen transactions?

No. The service stores only your public key. Decryption happens on your device, so servers see ciphertext.

Does the API key alone unlock my data?

No. The X-Api-Key header authenticates the request, but readable output requires your private key from credentials.json.
