Nordic Choice Club Mastercard Open Banking API

Cardholders who spend on a Nordic Choice Club Mastercard build up a stream of loyalty transactions worth watching — points runs, hotel stays, everyday purchases. open-banking.io lets you pull that card data into one private dashboard under PSD2, so you can track spending or feed it into your own tools without handing raw statements to anyone.

Nordic Choice Club Mastercard is a personal credit card, so open-banking.io exposes it as a personal account. There is no published BIC for the card programme, and open-banking.io simply routes you to the card's own login instead. Each authorisation lasts up to 180 days, after which you re-approve access from the dashboard.

How to connect Nordic Choice Club Mastercard

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

  1. Sign up at open-banking.io and set an encryption passphrase. Your keys are generated on your own device, so only you can later decrypt anything.
  2. In the dashboard, search for Nordic Choice Club Mastercard and choose the personal account type.
  3. You are redirected to Nordic Choice Club Mastercard's own secure login to approve access (the PSD2 consent screen). open-banking.io never sees your card credentials.
  4. Once approved, your card and transactions sync back into the dashboard automatically.

Access your data

Reading the data programmatically is an optional developer step you take after connecting. From the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. Then use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests carry the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — they cannot connect a card themselves.

Because the service is zero-knowledge and certificate-free, its servers hold only your public key and can never read your card data. All of this runs for around EUR 3 per month.

FAQ

Is my Nordic Choice Club Mastercard login shared with open-banking.io?

No. You authenticate directly on Nordic Choice Club Mastercard's own consent screen. open-banking.io only receives access you explicitly approve.

Can I read transactions with just an API key?

No. An API key alone returns ciphertext. Readable data requires your private decryption key from credentials.json, which stays on your device.

How long does access last?

Up to 180 days per consent, then you re-approve from the dashboard.
