Finnair Plus Mastercard Open Banking & API Access

Pulling your own spending history off the Finnair Plus Mastercard should not require a bank licence or a stack of eIDAS certificates. With open-banking.io you link the card once and then see its balances and transactions inside a single dashboard — and, if you write code, read the same data from your terminal. It is a certificate-free PSD2 service covering 2,600+ European banks, and because every record is decrypted on your own device with a key only you hold, nobody at open-banking.io can ever see your statements.

Finnair Plus Mastercard is offered in Sweden as a personal card, so open-banking.io exposes personal account access for it. Consent you grant lasts up to 180 days before a quick re-approval is needed, and no BIC is required to connect (BIC: n/a).

How to connect Finnair Plus Mastercard

Connecting happens entirely in the open-banking.io dashboard — there is no API call, key, or code involved in this step:

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally on your device, so the passphrase never leaves it.
  2. In the dashboard, search for and select Finnair Plus Mastercard and choose the personal account type.
  3. You are redirected to Finnair Plus Mastercard's own secure login to review and approve the PSD2 access request.
  4. Once approved, your card accounts sync back into the dashboard and refresh automatically.

Your credentials are only ever entered on the card issuer's own consent screen — open-banking.io never sees them.

Access your data

After the card is connected, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and each response is decrypted locally with your key. Without that private key an API key alone returns only ciphertext — which is exactly what keeps the service zero-knowledge.

All of this runs at roughly EUR 3/month, with no certificate paperwork.

Is a BIC needed to connect the card?

No. Finnair Plus Mastercard has no BIC listed here — you simply pick it by name in the dashboard.

Can open-banking.io read my card transactions?

No. The service stores only your public key, so data stays encrypted until your own device decrypts it.

Does the CLI connect the card for me?

No. The CLI and SDK only read and sync connections you have already approved in the dashboard; there is no connect command.
