Circle K EXTRA Mastercard API Access in Denmark

Pulling card data out of the Circle K EXTRA Mastercard by hand — logging in, exporting statements, reconciling fuel discounts and bonus lines — quickly becomes a chore. open-banking.io removes that friction by giving you a single, standards-based API endpoint that syncs your Circle K EXTRA Mastercard directly into whatever tool, spreadsheet or app you build. No screen scraping, no brittle PDF parsing, just a clean data feed.

The card behaves like any other regulated Danish payment product under PSD2, so once you grant consent, movements post to open-banking.io automatically and stay in sync.

• Balances — current outstanding balance and available credit in real time.

Consent and coverage

Circle K EXTRA Mastercard supports personal account types, with a maximum consent window of 180 days before re-authentication is required. No BIC is published for this product. open-banking.io connects to 2,600+ banks across the EU and UK, so the same integration extends far beyond a single card.

Privacy by design

open-banking.io runs a zero-knowledge architecture: your credentials go straight to the card issuer and are never stored by us. There are no certificates to buy, install or renew — authentication is handled entirely through the regulated open-banking flow, keeping your setup lightweight and your data yours.

Pricing

One flat subscription of roughly EUR 3/month covers your access — no per-call metering, no enterprise contracts, no hidden onboarding fees.
