Weberbank Open Banking & API Access Explained

Weberbank, the Berlin private bank (BIC WELADED1WBB), is reachable through open-banking.io — a zero-knowledge, certificate-free gateway to more than 2,600 European banks. Whether you keep a personal portfolio or run business accounts, you can pull balances and transactions into one place without eIDAS certificates, bespoke bank contracts, or a compliance project. open-banking.io leans on PSD2 access rights, and every figure you see is decrypted on your own device with a key only you hold.

How to connect Weberbank

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 cryptographic keys are generated locally on your device; the service only ever stores your public key.
  2. In the dashboard, search for Weberbank and choose the account type you need — business or personal.
  3. You are redirected to Weberbank's own secure login, where you approve access on the bank's PSD2 consent screen. Your credentials stay with Weberbank.
  4. Your accounts sync back into the dashboard, ready to view. Consent lasts up to 180 days, after which you simply re-approve on Weberbank's screen to keep the link alive.

Access your data

Once Weberbank is connected, developers can optionally read the data programmatically. 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 use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and each response is decrypted locally with your key. The API key alone only ever returns ciphertext; without your private key, nobody — not even open-banking.io — can read it. There is no connect command: the CLI and SDK only read and sync links you already created in the dashboard.
