Sparkasse Forchheim API Access & Open Banking

Reaching your Sparkasse Forchheim accounts programmatically usually means wrestling with PSD2 certificates and bank-by-bank onboarding. open-banking.io removes that entirely. It is a certificate-free, zero-knowledge service covering 2,600+ EU and UK banks — including Sparkasse Forchheim (BIC BYLADEM1FOR) — where every balance and transaction is decrypted locally with a key that never leaves your device. Both business and personal accounts are supported, and a single PSD2 consent stays valid for up to 180 days before you re-approve.

How to connect Sparkasse Forchheim

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 key pair is generated on your own device; open-banking.io only ever stores your public key.
  2. In the dashboard, search for Sparkasse Forchheim and choose whether you're linking a business or personal account.
  3. You're redirected to Sparkasse Forchheim's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Once approved, your accounts sync straight into your dashboard, ready to view.

That's the whole flow — you authenticate directly with Sparkasse Forchheim, never handing credentials to anyone else.

Access your data

Want your Sparkasse Forchheim data in code? That's an optional developer step, taken only after the connection exists. On the Developers page, create an API key and export a credentials.json bundling that key with your private decryption key. Then use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request carries your X-Api-Key header, and each response is decrypted locally with your own key. The API key alone returns only ciphertext — without your private key, nobody, including open-banking.io's servers, can read it. The CLI and SDK read and sync existing connections; they never create one.

All of this runs for roughly EUR 3/month, with no certificate paperwork and no per-bank contracts.

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

No. It's zero-knowledge — the service holds only your public key, so data is decrypted solely on your device.

Yes. Both business and personal Sparkasse Forchheim accounts are supported through the same dashboard flow.

How often do I re-authorize?

Your consent lasts up to 180 days, after which you simply re-approve on Sparkasse Forchheim's login screen.
