Consent and coverage

ING Wholesale Banking connections cover business account types, and a single authorisation stays valid for up to 180 days before ING requires you to renew consent. open-banking.io reaches 2,600+ banks across the EU and UK through one consistent interface, so ING sits alongside every other institution you already connect.

Privacy by design

The platform is zero-knowledge and certificate-free: you never upload eIDAS certificates or manage signing keys, and your banking data is not mined or resold. Credentials are entered only in the bank's environment, and access remains strictly read-only.

Pricing

One flat rate of roughly EUR 3 per month covers your access — no per-call fees, no enterprise contracts, and no separate certificate costs.
