Bring your Circle K EXTRA Mastercard into your own tools. With open-banking.io you can pull card account details, current balances and full transaction history from your Swedish Circle K EXTRA Mastercard through a single, standardised open-banking connection — no scraping, no screen logins, no certificate wrangling. Whether you are building a personal budget tracker, reconciling fuel spend or feeding an accounting workflow, the data arrives clean and ready to use.

Circle K EXTRA Mastercard is a co-branded fuel and loyalty card issued in Sweden by SEB Kort Bank AB. Because it is a payment card account, open-banking.io treats it like any other personal account: read access to what you spend, where and when.

What data you can access

  • Accounts — card account identifiers and metadata (personal account types).
  • Balances — outstanding balance and available figures.
  • Transactions — dated line items with amounts, merchants and references.

Consent lasts up to 180 days before the card holder re-authorises, keeping you aligned with PSD2 rules. There is no BIC on file for this card, and only personal account types are supported. open-banking.io reaches 2,600+ banks across the EU and UK, so the same integration scales far beyond a single issuer.

Privacy by design

We run a zero-knowledge architecture — your credentials go straight to the issuer and are never stored by us. The setup is certificate-free, so there are no eIDAS certificates or QWACs to obtain or renew. You get clean access without holding sensitive security material.

Pricing

One flat plan of roughly EUR 3/month covers your access — no per-call surcharges, no enterprise onboarding fees.

FAQ

Is my Circle K EXTRA Mastercard login shared with open-banking.io?

No. Authentication happens on the issuer's own page, and our zero-knowledge design means we never see or keep your credentials.

Every 180 days at most. After that the card holder simply re-authorises to keep the connection active.

Can I read historical transactions?

Yes. Once consent is granted you can retrieve available transaction history alongside live balances for the card account.
