ING Bank Śląski API Access for Accounts & Data

Pulling live data out of ING Bank Śląski (BIC INGBPLPW) usually means wrestling with PSD2 certificates, sandbox registrations and per-bank quirks. open-banking.io removes all of that. Point one API at ING Bank Śląski and start syncing account details, balances and transaction history for both personal and business customers in Poland — no eIDAS certificate, no direct bank onboarding, no maintenance of a bespoke integration.

How to connect ING Bank Śląski

  1. Create an open-banking.io account and grab your API key.
  2. Call the connect endpoint with the ING Bank Śląski institution ID.
  3. Redirect the customer to ING's own login and strong customer authentication.
  4. Receive the authorised consent token back at your callback URL.
  5. Query accounts, balances and transactions through a single unified schema.

What data you can access

  • Accounts — IBANs, currency, product type and holder details for personal and business accounts.
  • Balances — current and available balances, refreshed on demand.
  • Transactions — booked and pending entries with counterparty, amount, dates and reference text.

Every ING Bank Śląski response is normalised into the same JSON shape you use for every other institution, so adding Poland to a multi-country product is a configuration change rather than a rebuild.

ING Bank Śląski consents last up to 180 days before the customer needs to re-authenticate, giving you long-lived read access without frequent re-prompts. open-banking.io reaches 2,600+ banks across the EU and UK, so ING Bank Śląski slots into the same account-linking flow as every other supported institution.

Privacy by design

The platform is zero-knowledge: your customers' banking data flows straight through to you and is never mined, resold or retained beyond what the connection requires. Because the service is certificate-free, you skip the cost and delay of obtaining and rotating QWAC/QSEAL certificates entirely.

Pricing

Flat and predictable at roughly EUR 3 per month — no per-call surcharges, no enterprise minimums, no setup fee for accessing ING Bank Śląski.

Do I need a PSD2 licence to use this?

No. open-banking.io provides the regulated access layer, so you can connect to ING Bank Śląski without holding your own licence or certificates.

How often can I refresh ING Bank Śląski data?

You can request fresh balances and transactions on demand throughout the 180-day consent window before the customer re-authenticates.

Does this cover business accounts too?

Yes. Both personal and business ING Bank Śląski accounts are supported through the same API and data model.
