Kreissparkasse Waiblingen API Access & Open Banking

Pulling account and transaction data out of Kreissparkasse Waiblingen normally means wrestling with PSD2 certificates, eIDAS registration and a sandbox onboarding process. open-banking.io removes all of that. It is a certificate-free bridge to more than 2,600 European banks that lets you read your Kreissparkasse Waiblingen data through one dashboard — and, if you write code, through a small CLI and REST API. Everything stays private because your data is decrypted locally with a key that never leaves your device.

Kreissparkasse Waiblingen (BIC SOLADES1WBN) is supported for both business and personal accounts, and a single approval keeps your access live for up to 180 days before you renew it.

How to connect Kreissparkasse Waiblingen

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, no code and no key involved in this step.

  1. Sign up for open-banking.io and set your encryption passphrase. Your personal key pair is generated right there on your own device.
  2. In the dashboard, search for Kreissparkasse Waiblingen and choose whether you are linking a business or personal account.
  3. You are redirected to Kreissparkasse Waiblingen's own secure login, where you approve access on the bank's official PSD2 consent screen.
  4. Once the bank confirms, your accounts and transactions sync straight into your open-banking.io dashboard.

That is the whole flow. You never hand credentials to open-banking.io — authentication stays on the bank's side.

Access your data

Reading data programmatically is an optional step you take after the connection exists. Open the Developers page, create an API key and export a credentials.json — this file bundles your API key together with your private decryption key. From there you can run the CLI (openbanking accounts, openbanking transactions, openbanking sync) or call the REST API and SDKs. 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 — they cannot create new ones.

Because open-banking.io is zero-knowledge, its servers hold only your public key. An API key on its own returns ciphertext; without your private key it stays unreadable. Access costs roughly EUR 3/month.
