Alior Bank API Access — Poland Open Banking

Pulling live data out of Alior Bank shouldn't mean wrestling with eIDAS certificates or bank-specific onboarding. With open-banking.io you reach Alior Bank through a single REST interface and keep your users' account information flowing into your product automatically. Whether you're building bookkeeping, lending, or personal-finance tooling, one integration lets you sync Alior Bank data as soon as the customer grants consent.

How to connect Alior Bank

  1. Sign up for an open-banking.io account and grab your API key.
  2. Create an authorization link that points the customer to Alior Bank.
  3. The customer logs in on Alior Bank's own screens and approves the access scope.
  4. We hand back an access token tied to that consent.
  5. Call the accounts, balances, and transactions endpoints to begin syncing.

No sandbox paperwork, no per-bank contracts — the same request shape works across every institution we support.

What data you can access

Once consent is live you can read account details (IBAN, currency, holder), current and available balances, and full transaction history with amounts, dates, counterparties, and reference text. Both personal and business accounts held at Alior Bank are covered, so the same flow serves individual users and company clients alike.

Alior Bank grants a maximum consent lifetime of 180 days, after which the customer simply re-authorizes to keep the connection active. Alior Bank does not expose a BIC through this channel, so match accounts by IBAN. open-banking.io connects 2,600+ banks across the EU and UK, meaning Alior Bank is one endpoint among a continent-wide network you can expand into later without new code.

Privacy by design

We run a zero-knowledge model: credentials are entered only on Alior Bank's pages, and we never store your users' banking passwords. The service is certificate-free — there's no PSD2 QWAC or QSeal to buy, renew, or manage on your side. You get compliant access without becoming a licensed institution yourself.

Pricing

Access starts at roughly EUR 3 per month, a flat, predictable cost with no setup fees or per-call surprises.
