  2. Select Stadtsparkasse Düsseldorf from the list of 2,600+ supported EU and UK banks.

What data you can access

  • Accounts — IBAN, account type and holder metadata for personal and business accounts
  • Balances — current and available balances, refreshed on demand
  • Transactions — dated, categorisable transaction records with counterparty details

Each authorisation lasts for a maximum consent window of 180 days, after which the account holder simply re-confirms access. open-banking.io connects to more than 2,600 banks across Europe and the UK, so once your Stadtsparkasse Düsseldorf integration works, expanding to other institutions needs no new code.

Privacy by design

The platform is zero-knowledge and certificate-free: there are no eIDAS certificates to obtain, host or renew, and your users' credentials are never exposed to your systems. Data flows through regulated, consent-driven channels only, keeping the integration lightweight and compliant.

Pricing

Access starts at roughly EUR 3 per month — a flat, predictable cost with no per-call surprises and no enterprise onboarding overhead.
