ING Wholesale Banking France API Access | Open Banking

Corporate treasurers and finance teams working with ING Wholesale Banking in France need clean, programmatic access to their account and transaction data. open-banking.io gives you that access without certificates, without a bespoke bank integration, and without ever handing your data to a third party in readable form. It is a zero-knowledge service covering 2,600+ banks across the EU and UK, where everything you retrieve is decrypted locally with a key that only you hold.

ING Wholesale Banking is ING's corporate and institutional arm, so the connection here covers business account types. There is no BIC on file for this branch, and your consent under PSD2 can run for up to 180 days before it needs renewing.

How to connect ING Wholesale Banking

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your key pair is generated on your own device, so the service only ever sees your public key.
  2. In the dashboard, search for ING Wholesale Banking and select the business account type.
  3. You are redirected to ING Wholesale Banking's own secure login, where you approve access on the bank's consent screen (the standard PSD2 flow).
  4. Once approved, your accounts sync back into your open-banking.io dashboard, ready to view.

Because your data is encrypted with your local key, open-banking.io's servers store only ciphertext — they cannot read or decrypt what flows through them.

Access your data

After your bank is connected, developers can optionally pull the data 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 you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. An API key alone only ever returns ciphertext — without your private key it stays unreadable. Note the CLI and SDK only read and sync connections you already made in the dashboard; there is no connect command.

All of this runs for roughly EUR 3/month.

Do I need a certificate or QWAC to connect?

No. open-banking.io is certificate-free — you approve access on ING Wholesale Banking's own login screen and never manage eIDAS certificates yourself.

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

No. The service is zero-knowledge and holds only your public key. Your data is decrypted on your device with a private key that never leaves it.

How long does my access last?

ING Wholesale Banking permits consent windows of up to 180 days, after which you re-approve access through the dashboard.
