Sparkasse Salem-Heiligenberg Open Banking API
Reaching your Sparkasse Salem-Heiligenberg accounts programmatically used to mean bank certificates, a licensed PSD2 gateway, and weeks of paperwork. open-banking.io removes all of that. It gives you a single dashboard that speaks to Sparkasse Salem-Heiligenberg (BIC SOLADES1SAL) under PSD2, covering both business and personal accounts, and hands you clean balances and transactions instead of scraped HTML. Because the platform is zero-knowledge, your financial data is decrypted only on your own device with a key that never leaves it.
How to connect Sparkasse Salem-Heiligenberg
Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key involved in this step.
- Sign up for open-banking.io and set your encryption passphrase. Your key pair is generated locally on your device; open-banking.io only ever stores your public key.
- In the dashboard, choose Sparkasse Salem-Heiligenberg from the bank list and pick the account type you want to link — business or personal.
- You are redirected to Sparkasse Salem-Heiligenberg's own secure login and consent screen, where you approve access directly with the bank. Your credentials are never seen by open-banking.io.
- Once approved, your accounts sync into the dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.
Access your data
After a connection exists, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json file — it 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 every response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already approved in the dashboard — they never create one. An API key on its own returns only ciphertext; without your private key, nobody, including open-banking.io, can read it.
The service is certificate-free and costs around EUR 3/month.
