What data you can access

  • Accounts — IBANs, account names, currency and product metadata.
  • Balances — current and available amounts, refreshed on demand.
  • Transactions — booked and pending entries with dates, counterparties and references.

Access is granted under Europe's PSD2 rules. A single approval stays valid for up to 180 days, after which the account holder simply re-authorises. Consent is scoped, revocable and always controlled by your customer — you only see what they explicitly permit.

Privacy by design

open-banking.io is zero-knowledge: your customers' banking credentials are entered only on Stadtsparkasse Solingen's own login screen, never on ours, and we don't retain them. There is no certificate setup, no eIDAS QWAC to purchase and no PKI to maintain — authentication is handled for you, so integration stays clean.

Pricing

One flat plan of roughly EUR 3/month covers Stadtsparkasse Solingen alongside the full network of 2,600+ banks. No per-connection fees and no enterprise contract to negotiate before you start building.
