Weser-Elbe Sparkasse API Access & Open Banking

Reaching your Weser-Elbe Sparkasse account data no longer means wrestling with bank certificates or building a PSD2 stack from scratch. open-banking.io gives you a single, private doorway to your Weser-Elbe Sparkasse business and personal accounts (BIC BRLADE21BRS) across the EU and UK, covering 2,600+ institutions. Everything you retrieve is decrypted locally with a key that never leaves your device, so the service holds only your public key — it can never read your balances or transactions.

How to connect Weser-Elbe Sparkasse

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 right there on your own device.
  2. In the dashboard, pick Weser-Elbe Sparkasse and choose the account type you want to link — business or personal are both supported.
  3. You are redirected to Weser-Elbe Sparkasse's own secure login and consent screen, where you approve access under PSD2. Your credentials stay with the bank.
  4. Your approved accounts sync straight into your dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Once an account is linked, 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. An API key on its own returns only ciphertext — without your private key the data stays unreadable, which is exactly what zero-knowledge means. Note there is no connect command: the CLI and SDK only read and sync connections you already made in the dashboard.

At roughly EUR 3/month, you get certificate-free, privacy-first access without maintaining any banking infrastructure.

Does open-banking.io ever see my Weser-Elbe Sparkasse data?

No. It stores only your public key. All decryption happens on your device, so balances and transactions remain private to you.

Yes. Weser-Elbe Sparkasse supports both account types — link them separately in the dashboard, each with its own bank consent.

Weser-Elbe Sparkasse permits up to 180 days per approval. When it lapses, re-approve on the bank's own consent screen from your dashboard.
