Finnair Plus Mastercard API Access | Open Banking

Bring your Finnair Plus Mastercard account into your own tools with a single open-banking connection. open-banking.io lets developers, finance teams, and personal-finance builders in Finland read card data programmatically — no scraping, no manual CSV exports, and no per-bank paperwork. One integration, one API, and your Finnair Plus Mastercard data flows straight into whatever you're building.

Because open-banking.io already speaks to 2,600+ banks and card issuers across the EU and UK, adding Finnair Plus Mastercard is the same call you'd make for any other account. You write to our API once and reuse it everywhere.

How to connect Finnair Plus Mastercard

  1. Create an open-banking.io account and grab your API key.
  2. Call the endpoint list and select Finnair Plus Mastercard (Finland) as the target institution.
  3. Redirect the cardholder to their bank's own login and strong customer authentication screen.
  4. The cardholder approves consent — nothing sensitive ever passes through your servers.
  5. Receive a token and start pulling account, balance, and transaction data.

What data you can access

  • Accounts — personal card account identifiers and metadata.
  • Balances — current and available balances in near real time.
  • Transactions — dated, categorised card movements for reconciliation, budgeting, or analytics.

Finnair Plus Mastercard supports personal account types. No BIC is required to route the connection through our API — you simply reference the institution directly.

A single cardholder consent stays valid for up to 180 days before re-authentication is needed, so long-running dashboards and accounting syncs keep working without constant prompts. Coverage runs through the same PSD2 rails your bank already exposes.

Privacy by design

open-banking.io is zero-knowledge: credentials are entered only on the bank's page, and we never see or store them. There are no eIDAS certificates to buy, register, or renew — we are certificate-free, so you skip the compliance overhead that usually blocks smaller teams from open banking.

Pricing

Access starts at roughly EUR 3 per month — flat, predictable, and with no enterprise contract required to get going.

FAQ

Do I need my own open-banking licence?

No. open-banking.io operates under the required EU regulatory permissions, so you connect Finnair Plus Mastercard without holding your own licence or certificates.

How often can I refresh the data?

As often as your app needs within a consent window. One approval lasts up to 180 days before the cardholder re-authenticates.

Is my card login shared with you?

Never. Authentication happens entirely on the bank's own screen under our zero-knowledge model — we only receive the access token you're granted.
