• Balances — current and available figures, refreshed on demand.

Consent and coverage

Sparkasse Gelsenkirchen supports both business and personal account types. A single approval stays valid for up to 180 days before the customer re-authenticates, so you can keep long-running syncs alive without repeated prompts. Coverage is delivered under PSD2 access rules across the EU.

Privacy by design

open-banking.io is zero-knowledge: credentials are entered only on the bank's own page, and we never see or store them. The platform is certificate-free, so you skip the cost and delay of managing QWAC/QSEAL certificates. Data flows straight to you, encrypted in transit.

Pricing

One flat plan of roughly EUR 3/month unlocks every supported bank, including Sparkasse Gelsenkirchen — no per-connection fees or setup charges.
