Sparkasse Bergkamen-Bönen API Access & Open Banking

Reaching your Sparkasse Bergkamen-Bönen accounts programmatically usually means TPP licences, eIDAS certificates and a stack of PSD2 paperwork. open-banking.io removes all of that. It links your Sparkasse Bergkamen-Bönen accounts (BIC WELADED1BGK) through the regulated PSD2 channel and hands you clean, decrypted data — while keeping the service certificate-free and zero-knowledge, so only you can ever read what syncs.

Both business and personal Sparkasse Bergkamen-Bönen accounts are supported, and a single consent stays valid for up to 180 days before the bank asks you to re-approve.

How to connect Sparkasse Bergkamen-Bönen

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 your encryption passphrase. Your keys are generated locally on your own device, so the platform never holds your private key.
  2. In the dashboard, pick Sparkasse Bergkamen-Bönen and choose the account type — business or personal.
  3. You are redirected to Sparkasse Bergkamen-Bönen's own secure login and consent screen, where you approve access directly with the bank.
  4. Once approved, your accounts and transactions sync back into your dashboard automatically.

That's the whole flow: authenticate on the bank's side, and your data appears — encrypted end to end.

Access your data

Reading the data programmatically is an optional step for developers, taken after a connection exists. On the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key.

With that in place you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command.

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