Sparkasse Freising API Access & Open Banking

Reaching your Sparkasse Freising account data used to mean wrestling with bank certificates, developer portals and PSD2 paperwork. open-banking.io removes all of that. It is a zero-knowledge, certificate-free bridge to more than 2,600 European banks, and Sparkasse Freising (BIC BYLADEM1FSI) is one of them. Whether you hold a personal or a business account, you can link it once and keep a live, synced view of balances and transactions — with the data decrypted only on your own device.

How to connect Sparkasse Freising

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 cryptographic keys are generated locally on your device, so only you ever hold the private key.
  2. In the dashboard, search for Sparkasse Freising and choose the account type you want to link — business or personal.
  3. You are redirected to Sparkasse Freising's own secure login, where you approve access on the bank's PSD2 consent screen. A single consent stays valid for up to 180 days before you renew it.
  4. Your accounts then sync straight into your open-banking.io dashboard, ready to view.

Access your data

Once Sparkasse Freising is connected, reading the data programmatically is an optional developer step. Open 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. Every request carries the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read and sync connections you have already made — they never establish one.

Because open-banking.io is zero-knowledge, its servers only ever hold your public key. An API key alone returns ciphertext; without your private key it is unreadable. All of this runs at around EUR 3 per month.

Do I need a bank certificate for Sparkasse Freising?

No. open-banking.io is certificate-free. You authorise access directly on Sparkasse Freising's consent screen — no eIDAS certificate or bank agreement required.

Can open-banking.io read my Sparkasse Freising data?

No. Data is decrypted only on your device with a key that never leaves it. The service stores your public key, so it cannot read your transactions.

Sparkasse Freising permits a maximum consent window of 180 days. After that you simply re-approve access on the bank's login screen to keep syncing.
