Bank für Sozialwirtschaft API Access & Open Banking

Bank für Sozialwirtschaft AG serves Germany's social economy — charities, welfare organisations, and care providers — and its accounts hold data you may want to read from your own tools. open-banking.io gives you PSD2 access to Bank für Sozialwirtschaft (BIC BFSWDE33XXX) without registering as a licensed third party or wrangling eIDAS certificates. It covers business and personal accounts, and every consent lasts up to 180 days before you renew it.

Unlike raw bank APIs, open-banking.io is zero-knowledge: the encryption keys are generated on your own device, and account data is decrypted locally with a key only you hold. The service stores just your public key, so it can never read your balances or transactions. No certificate, no bank-specific onboarding — one dashboard for 2,600+ banks at roughly EUR 3/month.

How to connect Bank für Sozialwirtschaft

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 an encryption passphrase. Your keys are created locally on your device at this moment.
  2. In the dashboard, pick Bank für Sozialwirtschaft and choose the account type (business or personal).
  3. You are redirected to Bank für Sozialwirtschaft's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync back into the dashboard, ready to view — no developer setup needed.

Access your data

Once a 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. An API key alone only ever returns ciphertext; without your private key, nobody — not even open-banking.io — can read it. The CLI and SDK only read and sync existing connections; they never create one.

Do I need an eIDAS certificate for Bank für Sozialwirtschaft?

No. open-banking.io handles the regulated PSD2 layer, so you connect through the dashboard without any certificate.

Can open-banking.io see my Bank für Sozialwirtschaft transactions?

No. The service is zero-knowledge and holds only your public key; decryption happens on your device.

How long does access last?

Each Bank für Sozialwirtschaft consent is valid for up to 180 days, after which you re-approve it on the bank's login screen.
