Sparkasse Markgräflerland API Access & Open Banking

Reaching your Sparkasse Markgräflerland account data no longer means wrestling with eIDAS certificates or a bank sandbox. open-banking.io gives you a single, standards-based path into your Baden-Württemberg Sparkasse balances and transactions — with the twist that everything is decrypted on your own device, never on a server. Sparkasse Markgräflerland (BIC SOLADES1MGL) is reachable for both business and personal accounts, and a single approval keeps data flowing for up to 180 days before you re-confirm.

How to connect Sparkasse Markgräflerland

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; only you ever hold the private key.
  2. In the dashboard, pick Sparkasse Markgräflerland from the bank list and choose the account type you need — business or personal.
  3. You are redirected to Sparkasse Markgräflerland's own secure login, where you approve access under PSD2. Your credentials only ever touch the bank.
  4. Once approved, your accounts sync straight into the dashboard, ready to view. The consent stays valid for up to 180 days.

Access your data

Want to pull the data programmatically? That is an optional developer step, taken only after the connection above exists. 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:

  • Use the CLI: openbanking accounts, openbanking transactions, or openbanking sync.
  • Or call the REST API / SDK, sending your key in the X-Api-Key header.

There is no connect command — the CLI and SDK only read and refresh connections you already made in the dashboard. Every response arrives encrypted and is decrypted locally with your private key. Supply the API key alone and you get nothing but ciphertext back.

That is the heart of the zero-knowledge, certificate-free design: open-banking.io stores only your public key, so its servers can never read your Sparkasse Markgräflerland data. Coverage spans 2,600+ EU/UK banks for around EUR 3/month.
