Sparkasse Gera-Greiz API Access & Open Banking

Reaching your Sparkasse Gera-Greiz account data no longer means wrestling with bank-specific certificates or a stack of PSD2 paperwork. open-banking.io gives you a single, privacy-first route to your Thuringian Sparkasse: your balances and transactions are encrypted end-to-end and decrypted only on your own device, using a key that never leaves your hands. Whether you run a business account or a personal one at Sparkasse Gera-Greiz (BIC HELADEF1GER), the process is the same, and it works across 2,600+ EU and UK banks for one flat subscription.

How to connect Sparkasse Gera-Greiz

Connecting happens entirely in 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 open-banking.io only ever holds your public key.
  2. In the dashboard, choose Sparkasse Gera-Greiz and select your account type — business or personal.
  3. You are redirected to Sparkasse Gera-Greiz's own secure login and consent screen, where you approve access directly with the bank (standard PSD2 authorisation).
  4. Once approved, your accounts sync back into your dashboard. Consent lasts up to 180 days, after which you simply re-approve.

Access your data

Reading the data programmatically is an optional developer step you take only after the connection above exists. From the Developers page, create an API key and export a credentials.json file, which bundles that API key together with your private decryption key. You can then 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 servers only ever store ciphertext. Note that the CLI and SDK read and sync existing connections; they never connect a bank themselves.
