Sparkasse Erlangen Höchstadt Herzogenaurach API access

Reading account and transaction data from Sparkasse Erlangen Höchstadt Herzogenaurach no longer means chasing eIDAS certificates or building a bespoke PSD2 stack. open-banking.io gives you standardized, consent-based access to this Middle Franconian Sparkasse (BIC BYLADEM1ERH) across both business and personal accounts — with the important twist that your banking data is decrypted only on your own device, using a key nobody else holds.

How to connect Sparkasse Erlangen Höchstadt Herzogenaurach

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key involved in the linking step.

1. Sign up for open-banking.io and set your encryption passphrase. Your cryptographic keys are generated locally on your device at this moment.
2. In the dashboard, pick Sparkasse Erlangen Höchstadt Herzogenaurach and choose the account type — business or personal.
3. You are redirected to Sparkasse Erlangen Höchstadt Herzogenaurach's own secure login, where you approve access on the bank's PSD2 consent screen. Consent can be granted for up to 180 days before you renew it.
4. Your accounts sync back into your dashboard, ready to view.

Because approval always occurs on the bank's own page, open-banking.io never sees your credentials.

Access your data

Once a connection exists, developers can optionally read it programmatically. Open the Developers page, create an API key, and export a credentials.json that bundles the API key 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 SDKs only read and sync connections you already approved — they never create one.

This is the certificate-free, zero-knowledge model: open-banking.io stores only your public key, so its servers hold ciphertext they cannot read. All of it runs at roughly EUR 3/month across 2,600+ supported EU/UK banks.

Is a bank API key needed to link the account?

No. Linking is done in the dashboard by approving on the bank's consent screen. API keys are only for reading data afterward.

Which Sparkasse Erlangen Höchstadt Herzogenaurach accounts are supported?

Both business and personal accounts, reachable under BIC BYLADEM1ERH.

Can open-banking.io staff see my transactions?

No. Data is decrypted only on your device with a key you alone hold; the service stores just your public key.
