Sparkasse Vorpommern API Access & Open Banking

Reach your Sparkasse Vorpommern accounts through a single, privacy-first workspace. open-banking.io links to Sparkasse Vorpommern (BIC NOLADE21GRW) under PSD2, covering both business and personal account types, and keeps your financial data encrypted with a key that never leaves your device. There are no eIDAS certificates to buy and no bank-specific paperwork — you sign in, approve access, and your balances and transactions appear in your dashboard.

How to connect Sparkasse Vorpommern

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

  1. Create an open-banking.io account and set your encryption passphrase. The keys that protect your data are generated locally on your own device.
  2. In the dashboard, search for Sparkasse Vorpommern and choose whether you're linking a business or personal account.
  3. You're redirected to Sparkasse Vorpommern's own secure login, where you approve the connection on the bank's PSD2 consent screen.
  4. Your accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply reauthorise from the same screen.

Because approval takes place on Sparkasse Vorpommern's own systems, open-banking.io never sees your banking credentials.

Access your data

Reading Sparkasse Vorpommern data programmatically is an optional developer step, 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 you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request carries your key in the X-Api-Key header, and each response is decrypted locally on your machine. The CLI and SDK only read and sync connections that already exist — they cannot create one.

This is what zero-knowledge means in practice: open-banking.io stores only your public key, so its servers hold ciphertext they cannot read. An API key alone returns encrypted data; without your private key it stays unreadable. All of this runs for around EUR 3/month.

Does open-banking.io store my Sparkasse Vorpommern password?

No. You authenticate directly on Sparkasse Vorpommern's own login and consent pages; open-banking.io never receives your credentials.

Yes. Sparkasse Vorpommern supports both account types — link each one separately from the dashboard.

How long does access last before I reconnect?

PSD2 consent runs for up to 180 days. When it expires, reauthorise Sparkasse Vorpommern from the dashboard in a few clicks.
