ING Wholesale Banking (Austria) API Access & Open Banking

Reaching your ING Wholesale Banking (Austria) account data no longer means wrestling with eIDAS certificates or a bespoke corporate integration. open-banking.io gives you a single, PSD2-compliant path to your Austrian ING Wholesale Banking business accounts — and because it is zero-knowledge, your financial data is decrypted only on your own device with a key that never leaves it. open-banking.io's servers hold nothing but your public key.

ING Wholesale Banking (Austria) is one of 2,600+ institutions reachable this way. It exposes business accounts, and a single consent stays valid for up to 180 days before you renew it. No BIC is required to get started here.

How to connect ING Wholesale Banking

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your cryptographic keys are generated locally, on your device.
  2. In the dashboard, pick ING Wholesale Banking (Austria) and choose the business account type.
  3. You are redirected to ING Wholesale Banking's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your approved accounts sync back into your open-banking.io dashboard automatically.

That's the whole connection flow. Because you authorise directly on ING's own environment, your credentials are never seen by open-banking.io.

Access your data

Once the account is linked, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this bundles the API key together 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. Without that private key, the API returns only ciphertext — even to you. The CLI and SDK only read or sync existing connections; they never create one.

All of this runs for roughly EUR 3/month, with no certificate purchase or setup fee.

Does ING Wholesale Banking (Austria) support personal accounts here?

No — only business accounts are available for this branch.

Up to 180 days per approval, after which you re-confirm access from the dashboard.

Can open-banking.io read my ING data?

No. It is zero-knowledge and stores only your public key; decryption happens on your device.
