Sparkasse Prignitz Open Banking & API Access Guide
Reaching your Sparkasse Prignitz balances and transactions no longer means wrestling with PSD2 certificates or building your own bank integration. open-banking.io gives you a single dashboard that links to Sparkasse Prignitz (BIC WELADED1PRP) and keeps every byte of account data encrypted with a key that never leaves your device. Both business and personal accounts are supported, and one consent stays valid for up to 180 days before you renew it.
Because the platform is zero-knowledge, its servers only ever hold your public key. Your statements, IBANs and transaction history are decrypted locally, so nobody at open-banking.io — or anywhere else — can read them.
How to connect Sparkasse Prignitz
Connecting happens entirely inside the open-banking.io dashboard, with no code or API call:
- Sign up for an open-banking.io account.
- Set an encryption passphrase. Your key pair is generated right there on your own device.
- In the dashboard, pick Sparkasse Prignitz and choose whether you are linking a business or personal account.
- You are redirected to Sparkasse Prignitz's own secure login, where you approve access on the bank's official PSD2 consent screen.
- Your accounts sync back into the dashboard, ready to view.
That approval on the bank's side is the only place your credentials are entered — open-banking.io never sees them.
Access your data
Once the connection exists, developers can optionally read it programmatically. 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, openbanking sync), an SDK, or the REST API. Every request carries the X-Api-Key header, and each response is decrypted locally with your key. An API key on its own returns only ciphertext, so your data stays useless to anyone without your private key. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command.
All of this runs for roughly EUR 3/month, with no eIDAS certificate to buy or renew.
Is my Sparkasse Prignitz login shared with open-banking.io?
No. You enter it only on Sparkasse Prignitz's own consent page; open-banking.io never receives it.
How often do I re-authorise?
Each consent lasts up to 180 days, after which you re-approve in the dashboard.
Can I use both business and personal accounts?
Yes — Sparkasse Prignitz supports both, and you choose the type when linking.
