Sparkasse im Landkreis Cham API Access & Open Banking

Reaching account data from Sparkasse im Landkreis Cham no longer means chasing bank certificates or building a PSD2 stack yourself. open-banking.io gives you a single, privacy-first path to the balances and transactions behind BIC BYLADEM1CHM, covering both business and personal accounts. Everything is decrypted on your own device with a key only you hold, so the service is genuinely zero-knowledge and certificate-free.

How to connect Sparkasse im Landkreis Cham

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; the servers only ever see your public key.
  2. In the dashboard, search for Sparkasse im Landkreis Cham and choose your account type — business or personal.
  3. You are redirected to Sparkasse im Landkreis Cham's own secure login, where you approve access on the bank's consent screen (standard PSD2 authorisation).
  4. Your approved accounts sync straight back into your dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Reading the data programmatically is an optional step for developers, taken after the connection above exists. From the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. Then 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. There is no connect command — the CLI and SDK only read and sync connections you already made in the dashboard.

All of this runs for around EUR 3 per month, with no per-bank certificate fees.
