Salzlandsparkasse Open Banking API Access Guide

Salzlandsparkasse serves the Salzlandkreis region of Saxony-Anhalt, and open-banking.io lets you reach its account data without certificates, bank-specific paperwork, or a screen-scraping workaround. Whether you hold a personal current account or run a business relationship with the bank (BIC NOLADE21SES), you get a single, PSD2-compliant path to your balances and transactions — encrypted so that only you can read them.

The defining trait of open-banking.io is that it is zero-knowledge. When you register, an encryption key is generated on your own device from a passphrase you choose. The service only ever stores your public key, so its servers physically cannot read or decrypt what flows through them. Salzlandsparkasse data is unlocked locally, on your machine, and nowhere else.

How to connect Salzlandsparkasse

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 keys are created locally at this moment.
  2. In the dashboard, search for Salzlandsparkasse and choose the account type you need — business or personal.
  3. You are redirected to Salzlandsparkasse's own secure login, where you approve access on the bank's PSD2 consent screen. Consent lasts up to 180 days, after which you simply renew it.
  4. Your approved accounts then sync back into your dashboard, ready to view.

Access your data

Reading your data programmatically is an optional step for developers, taken only after a connection exists. From the Developers page, create an API key and export a credentials.json file — this bundles the API key together with your private decryption key. With it you can run the CLI (openbanking accounts, openbanking transactions, openbanking sync), or call the SDK and REST API using the X-Api-Key header. Every response arrives encrypted and is decrypted locally with your own key. An API key on its own returns only ciphertext, which keeps the zero-knowledge guarantee intact. Access to the full service costs roughly EUR 3/month.

Do I need a developer account to connect?

No. Connecting Salzlandsparkasse is done in the dashboard by anyone. API keys are only for the optional programmatic read step.

Which Salzlandsparkasse accounts are supported?

Both business and personal accounts, identified by BIC NOLADE21SES, sync once you approve consent.

Can open-banking.io see my banking data?

No. It holds only your public key, so data is decrypted solely on your device.
