Sparkasse Amberg-Sulzbach Open Banking & API Access

Pulling account and transaction data out of Sparkasse Amberg-Sulzbach normally means wrestling with certificates, eIDAS credentials and PSD2 paperwork. open-banking.io removes that layer entirely. It reaches Sparkasse Amberg-Sulzbach (BIC BYLADEM1ABG) through regulated open-banking rails, covering both business and personal accounts, while every balance and payment record is decrypted on your own device with a key that never leaves it.

The service is zero-knowledge and certificate-free: open-banking.io holds only your public key, so its servers can sync ciphertext but can never read your finances. One flat subscription of roughly EUR 3/month covers Sparkasse Amberg-Sulzbach alongside 2,600+ other EU and UK banks.

How to connect Sparkasse Amberg-Sulzbach

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 an encryption passphrase. Your encryption keys are generated locally on your device from that passphrase.
  2. In the dashboard, pick Sparkasse Amberg-Sulzbach and choose the account type — business or personal.
  3. You are redirected to Sparkasse Amberg-Sulzbach's own secure login, where you approve access on the bank's PSD2 consent screen. Consent lasts up to 180 days before you renew it.
  4. Your approved accounts sync straight into your dashboard, already decrypted locally for you to view.

Access your data

Reading data programmatically is an optional developer step you take after the connection above 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. From there you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API.

Every request authenticates with the X-Api-Key header, and each response is decrypted locally with your own private key. An API key on its own only ever returns ciphertext — without your key, nobody, including open-banking.io, can read it. Note the CLI and SDK only read and sync existing connections; there is no connect command.
