Sparkasse Altenburger Land API & Open Banking Access

Pulling your Sparkasse Altenburger Land balances and transactions into your own tools usually means wrestling with bank certificates and PSD2 paperwork. open-banking.io removes that friction: it is a certificate-free service covering 2,600+ banks across the EU and UK, and it treats your Sparkasse Altenburger Land data as yours alone. Every figure that leaves the bank is encrypted on your device with a key only you hold, so the platform never sees your financial life in the clear.

Sparkasse Altenburger Land (BIC HELADEF1ALT) is supported for both business and personal accounts, and a single approval keeps your connection live for up to 180 days before you renew it.

How to connect Sparkasse Altenburger Land

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally on your device, and the passphrase never leaves it.
  2. In the dashboard, search for Sparkasse Altenburger Land and choose the account type you need — business or personal.
  3. You are redirected to Sparkasse Altenburger Land's own secure login, where you approve access under PSD2 (this is the consent that lasts up to 180 days).
  4. Once you confirm, your accounts sync back into the dashboard and stay refreshed.

That's the whole flow — you authenticate directly with the bank, never handing credentials to anyone else.

Access your data

Want your Sparkasse Altenburger Land data in scripts or a service? After the connection exists, developers can opt into programmatic access. On the Developers page, create an API key and export a credentials.json bundle — it holds the API key plus your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Calls send the X-Api-Key header, and every response is decrypted locally with your own key. An API key on its own only ever returns ciphertext, because open-banking.io's servers store just your public key and can never read your data.

All of this runs at roughly EUR 3/month.

Do I need a bank certificate or developer registration?

No. open-banking.io is certificate-free — you approve access on Sparkasse Altenburger Land's login screen and you're done.

Can open-banking.io see my transactions?

No. It is zero-knowledge and holds only your public key; decryption happens on your device with a key only you have.

How long does one approval last?

Up to 180 days for Sparkasse Altenburger Land, after which you simply re-approve in the dashboard.
