Sparkasse Chemnitz API Access & Open Banking Data

Reaching your Sparkasse Chemnitz account data usually means juggling clunky portals and eIDAS certificates. open-banking.io removes that friction: it is a certificate-free, zero-knowledge bridge to 2,600+ EU and UK banks that lets you pull balances and transactions from Sparkasse Chemnitz (BIC CHEKDE81XXX) into one dashboard. Both business and personal accounts are supported, and a single PSD2 consent covers you for up to 180 days before you renew.

How to connect Sparkasse Chemnitz

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 your encryption passphrase. Your keys are generated locally on your own device, so only you ever hold them.
  2. In the dashboard, search for and select Sparkasse Chemnitz, then choose the account type you want to link — business or personal.
  3. You are redirected to Sparkasse Chemnitz's own secure login, where you approve access on the bank's consent screen. Your credentials stay with the bank.
  4. Once approved, your accounts sync back into the dashboard and stay refreshed for the life of the 180-day consent.

Access your data

After a connection exists, developers can optionally read it programmatically. 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 use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command. Because open-banking.io holds only your public key, its servers can never read your data; an API key alone returns nothing but ciphertext.

All of this runs for roughly EUR 3 per month, with no certificate procurement and no data ever leaving your control unencrypted.
