Sparkasse Offenburg/Ortenau API Access & Open Banking
Reaching your Sparkasse Offenburg/Ortenau account data no longer means wrestling with certificates, sandboxes or a PSD2 licence. open-banking.io gives you a single, private path to your Ortenau-region balances and transactions — covering both business and personal accounts held at the bank (BIC SOLADES1OFG). Everything is decrypted locally with a key that never leaves your device, so the service itself only ever holds ciphertext it cannot read.
How to connect Sparkasse Offenburg/Ortenau
Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code or key involved in this step.
- Sign up for an open-banking.io account.
- Set your encryption passphrase. Your key pair is generated right there on your own device; open-banking.io keeps only the public key.
- In the dashboard, pick Sparkasse Offenburg/Ortenau from the bank list and choose the account type you want to link — business or personal.
- You are redirected to Sparkasse Offenburg/Ortenau'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.
- Your approved accounts sync straight into your dashboard, ready to view.
Access your data
Once the connection exists, developers can optionally read it 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 directly. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. The CLI and SDK only read and sync connections that already exist — there is no connect command, because linking a bank always happens in the dashboard.
That design is the whole point: it is zero-knowledge and certificate-free. An API key alone returns nothing but ciphertext — without your private key, the data stays unreadable, even to open-banking.io's servers. All of this runs for around EUR 3 per month.
Does open-banking.io work with business accounts at Sparkasse Offenburg/Ortenau?
Yes. Both business and personal accounts are supported; you choose the account type when you link the bank in the dashboard.
How long does my consent stay active?
Sparkasse Offenburg/Ortenau grants access for up to 180 days. After that you simply re-approve on the bank's consent screen.
Can open-banking.io see my banking data?
No. Decryption happens on your device with a key only you hold. The service stores your public key and encrypted data, so it can never read your balances or transactions.
