ING Wholesale Banking Spain API Access | Open Banking

Bring your ING Wholesale Banking (Spain) corporate data into your own systems without wrestling with proprietary bank connectors. open-banking.io gives you a single, standards-based API to sync ING Wholesale Banking account information — account details, balances and transaction history — into whatever tools your finance or treasury team already runs.

Whether you are building cash-position dashboards, automating reconciliation, or feeding an ERP, one integration is enough to keep Spanish corporate account data flowing in near real time.

1. Create an account on open-banking.io and choose ING Wholesale Banking (Spain) from the supported institutions.
2. Launch a consent request and authenticate directly with ING using your existing corporate banking credentials.
3. Approve the accounts you want to share — the authorisation stays with the bank, never with us.

ING Wholesale Banking is corporate-focused, so coverage here targets business account types.

Consent and coverage

Each authorisation is valid for up to 180 days, after which the account holder simply re-confirms consent. open-banking.io reaches 2,600+ banks across the EU and UK, so ING Wholesale Banking can sit alongside every other institution your organisation uses under one contract and one API.

Privacy by design

We are zero-knowledge and certificate-free. There are no eIDAS certificates to buy, register or renew — you connect through our regulated infrastructure. Credentials go straight to ING, and we never see or store your banking passwords.

Pricing

Flat, predictable access from around EUR 3 per month. No per-call surprises and no certificate overhead — just one subscription covering every connected bank.
