Sparkasse Kinzigtal API Access & Open Banking Data

Pulling live balances and transactions out of your Sparkasse Kinzigtal accounts usually means wrestling with PSD2 certificates and bank-specific gateways. open-banking.io removes that friction: it links to Sparkasse Kinzigtal (BIC SOLADES1HAL) on your behalf and hands you a clean, decrypted feed of your own data. Both business and personal accounts are supported, and a single consent stays valid for up to 180 days before you re-approve.

Because the platform is zero-knowledge and certificate-free, your account data is decrypted locally with a key only you hold — open-banking.io's servers keep only your public key and can never read your statements.

How to connect Sparkasse Kinzigtal

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 an open-banking.io account.
  2. Set an encryption passphrase. Your key pair is generated right on your device, so nobody else can reconstruct it.
  3. In the dashboard, search for Sparkasse Kinzigtal and choose the account type — business or personal.
  4. You are redirected to Sparkasse Kinzigtal's own secure login to approve access (the standard PSD2 consent screen).
  5. Once approved, your accounts sync back into the dashboard automatically.

Access your data

After the connection is live, 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 sends the X-Api-Key header, and each response is decrypted locally with your own key. Note that the CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command, and an API key on its own returns nothing but ciphertext without your private key.

All of this runs for roughly EUR 3/month.

Is a bank certificate or eIDAS setup required?

No. open-banking.io is certificate-free — you approve access on Sparkasse Kinzigtal's consent screen and never handle QWAC/QSeal certificates yourself.

Can open-banking.io see my Sparkasse Kinzigtal transactions?

No. The service is zero-knowledge and stores only your public key. Data is decrypted on your device with a key only you hold.

How long does access last before renewal?

Sparkasse Kinzigtal allows a maximum consent window of 180 days, after which you re-approve access in the dashboard.
