ING Spain API Access: Sync Bank Data in Minutes

Bring your ING (Spain) banking straight into your own tools. With open-banking.io you can pull a live picture of your ING accounts through a single, standardised API — no bespoke bank integration, no PSD2 certificate to obtain and renew. Point your app at open-banking.io and read ING data the moment a customer grants consent.

Whether you run a fintech product, an accounting workflow or an internal dashboard, syncing ING data becomes a few lines of code rather than a months-long onboarding project.

How to connect ING

1. Create an open-banking.io account and grab your API key.
2. Call the connect endpoint for ING (Spain), identified by BIC INGDESMMXXX.
3. Redirect the account holder to ING's secure login to approve access.
4. Receive the consent token and start requesting data — business or personal accounts are both supported.

What data you can access

• Accounts — IBANs, currency, product type and holder details for business and personal profiles.
• Balances — current and available balances, refreshed on demand.
• Transactions — booked and pending entries with amounts, dates, counterparties and references.

Consent and coverage

A single ING authorisation stays valid for up to 180 days before the customer needs to re-approve, so you get long-lived, low-friction access. The same integration reaches 2,600+ banks across the EU and UK, meaning ING is one connector among a whole continent — build once, expand everywhere.

Privacy by design

open-banking.io is zero-knowledge: credentials go directly to ING and never touch our servers, and we don't retain your customers' banking data. Because the platform is certificate-free, you skip the eIDAS/QWAC paperwork that normally gates open-banking access. You stay the sole custodian of what you sync.

Pricing

One flat plan of roughly EUR 3/month covers ING alongside every other supported bank — no per-call fees, no per-bank surcharges, no enterprise contract required.

FAQ

Is a bank licence or PSD2 certificate required to use ING data?

No. open-banking.io handles the regulated layer, so you connect to ING without holding your own certificate or licence.

Can I connect both business and personal ING accounts?

Yes. Both account types are supported through the same ING connector and consent flow.

How often do I need to renew ING consent?

ING consent lasts up to 180 days; after that the account holder simply re-authorises to keep the connection live.
