ING Wholesale Banking Ireland API Access | Open Banking

Treasury and finance teams running corporate accounts with ING Wholesale Banking in Ireland increasingly want their balances and transactions in their own tools — not locked behind a portal login. open-banking.io gives you PSD2 access to that data without certificates, eIDAS seals or a bank developer contract. It is a zero-knowledge service: your data is encrypted on your own device with a key only you hold, and open-banking.io's servers only ever store your public key.

ING Wholesale Banking (Ireland) is available for business account types. Access consent lasts up to 180 days before it needs renewing, and no BIC is required to set the connection up.

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 at open-banking.io and set your encryption passphrase. Your keys are generated locally on your device from that passphrase, so only you can later decrypt anything.
  2. In the dashboard, search for ING Wholesale Banking and pick the business account type.
  3. You are redirected to ING Wholesale Banking's own secure login, where you review and approve the access request (the standard PSD2 consent step) directly with the bank.
  4. Once approved, your accounts sync back into your open-banking.io dashboard, ready to view.

Because you authenticate on ING Wholesale Banking's own screen, open-banking.io never sees your banking credentials.

Access your data

Viewing accounts in the dashboard is enough for many teams. If you want the data programmatically, that is an optional developer step taken after the connection exists. 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 directly.

Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. An API key on its own only ever returns ciphertext — without your private key, there is nothing readable to see. The CLI and SDK read and sync connections you have already made; they cannot create a bank connection.

Pricing is around EUR 3/month for access to 2,600+ EU and UK banks.

Does open-banking.io work without eIDAS certificates?

Yes. There are no certificates to obtain or manage — sign up, set a passphrase and connect ING Wholesale Banking from the dashboard.

Can open-banking.io read my ING Wholesale Banking data?

No. It is zero-knowledge and holds only your public key. Data is decrypted locally with a private key that never leaves your device.

How long does my access stay active?

Up to 180 days per consent. After that you re-approve on ING Wholesale Banking's login screen to keep syncing.
