Sparkasse Stade - Altes Land Open Banking & API Access

Want programmatic, private access to your Sparkasse Stade - Altes Land accounts? open-banking.io links your business or personal accounts (BIC NOLADE21STS) to a single dashboard and, when you need it, to a clean developer workflow. It covers 2,600+ EU and UK banks, needs no eIDAS certificate, and keeps your data readable only by you — because decryption happens locally with a key that never leaves your device.

Every consent you grant Sparkasse Stade - Altes Land runs under PSD2 and stays valid for up to 180 days before you re-approve, so a connection you set up once keeps syncing without constant re-authentication.

How to connect Sparkasse Stade - Altes Land

Connecting happens entirely in the open-banking.io dashboard — there is no API call, code, or key involved in this step.

  1. Sign up at open-banking.io and set your encryption passphrase. Your keys are generated right there on your own device.
  2. In the dashboard, search for Sparkasse Stade - Altes Land and choose your account type — business or personal.
  3. You are redirected to Sparkasse Stade - Altes Land's own secure login, where you approve access on the bank's consent screen. Your credentials go only to the bank.
  4. Your accounts and transactions sync back into your dashboard, ready to view.

Access your data

Reading your data programmatically is an optional step for developers, available only after the connection above exists. 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 on your machine. The CLI and SDK only read and sync connections you already made — they never create one.

Because open-banking.io is zero-knowledge, its servers hold only your public key. An API key alone returns ciphertext; without your private key it stays unreadable. All this runs for around EUR 3/month.

Does open-banking.io see my Sparkasse Stade - Altes Land data?
