Sparkasse Schwäbisch Hall-Crailsheim API & Open Banking

Reaching your Sparkasse Schwäbisch Hall-Crailsheim balances and transactions in your own tools no longer means wrestling with PSD2 certificates or eIDAS registrations. open-banking.io gives you regulated access to this Baden-Württemberg Sparkasse (BIC SOLADES1SHA) through one dashboard, covering both business and personal accounts. Everything is decrypted on your device with a key only you hold — the service is zero-knowledge and certificate-free, so no QWAC or QSEAL setup is ever required.

How to connect Sparkasse Schwäbisch Hall-Crailsheim

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 key pair is generated locally on your own device; open-banking.io only ever stores your public key.
  2. In the dashboard, search for Sparkasse Schwäbisch Hall-Crailsheim and choose the account type you want — business or personal.
  3. You are redirected to Sparkasse Schwäbisch Hall-Crailsheim's own secure login, where you approve access on the bank's consent screen (standard PSD2 authorisation).
  4. Your approved accounts sync straight back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Once the connection exists, reading it programmatically is an optional developer step. On 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 directly. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, no one, including open-banking.io, can read it.

Do I need an eIDAS certificate for Sparkasse Schwäbisch Hall-Crailsheim?

No. open-banking.io handles the regulated connection, so you never register a certificate or provider licence to reach SOLADES1SHA accounts.

Can I connect business and personal accounts?

Yes. Both account types are supported. Pick the type when you select the bank in the dashboard, and repeat the flow to add more.

How does the CLI connect to my bank?

It doesn't — connecting only happens in the dashboard via Sparkasse Schwäbisch Hall-Crailsheim's consent screen. The CLI, SDK, and API only read and sync connections that already exist.

All of this runs for around EUR 3/month across 2,600+ EU and UK banks. Start at https://open-banking.io.
