Stadtsparkasse Remscheid API Access & Open Banking

Pulling live balances and transactions out of Stadtsparkasse Remscheid usually means wrestling with certificates and eIDAS paperwork. open-banking.io removes that entirely: it is a certificate-free bridge to 2,600+ EU and UK banks where every response is decrypted on your own device with a key only you hold. Your Stadtsparkasse Remscheid accounts (BIC WELADEDRXXX) become readable data without you ever handing a decryption key to anyone.

Both business and personal accounts are supported, and a single PSD2 approval stays valid for up to 180 days before Stadtsparkasse Remscheid asks you to renew it.

How to connect Stadtsparkasse Remscheid

Connecting happens entirely inside 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 device, so no one else can reconstruct them.
  2. In the dashboard, search for Stadtsparkasse Remscheid and choose the account type you want to link (business or personal).
  3. You are redirected to Stadtsparkasse Remscheid's own secure login, where you approve access on the bank's consent screen — your credentials only ever touch the bank.
  4. Once approved, your accounts sync back into the dashboard, ready to view.

Access your data

Reading the data programmatically is an optional developer step that comes after the account is already connected. 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, there is nothing readable to see.

All of this runs on a zero-knowledge model: open-banking.io stores only your public key and can never read your Stadtsparkasse Remscheid data. Pricing is roughly EUR 3/month.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free — you approve access directly on Stadtsparkasse Remscheid's consent page, nothing to install.

Can I access business accounts?

Yes. Both business and personal Stadtsparkasse Remscheid accounts can be linked and read the same way.

How often do I re-approve?

A Stadtsparkasse Remscheid consent lasts up to 180 days, after which you re-confirm access in the dashboard.
