Opel Mastercard API Access — Sweden Open Banking

Bring your Opel Mastercard (Opelkortet) into your own tools without copy-pasting statements. open-banking.io lets developers, fintechs and finance teams pull card account data straight from Sweden's banking rails through a single, standardised API — no PSD2 certificate estate and no direct integration work required.

Whether you are building expense automation, a personal finance dashboard or reconciliation tooling, syncing your Opelkortet takes minutes rather than a compliance project.

How to connect Opel Mastercard

  1. Create an account at open-banking.io and grab your API key.
  2. Select Opel Mastercard (Sweden) from the supported institution list.
  3. Redirect the cardholder to the secure authorisation screen to approve access.
  4. The cardholder confirms with their usual bank credentials — you never see them.
  5. Receive tokenised access and start reading data through the unified endpoints.

What data you can access

  • Accounts — personal card account identifiers and metadata
  • Balances — current and available balances in near real time
  • Transactions — historical and incoming card movements, cleanly categorised

Every response follows one consistent schema, so Opelkortet behaves like any of the 2,600+ banks already on the network.

Opel Mastercard supports personal account access. A single cardholder consent stays valid for up to 180 days before re-authorisation is needed, giving long-running integrations plenty of headroom. No BIC is required to route the connection — the institution selector handles it for you.

Privacy by design

open-banking.io is zero-knowledge: credentials are entered only on the bank's own screen and never touch our servers. There are no eIDAS or QWAC certificates for you to buy, host or rotate — we handle the regulated plumbing so you handle the product. Access is scoped, tokenised and revocable at any time.

Pricing

One flat subscription of roughly EUR 3/month covers full access — every bank, every endpoint, no per-call surprises or hidden onboarding fees.

Is the Opel Mastercard connection read-only?

Yes. The API exposes account, balance and transaction data for reading only — it cannot move money or alter your card.

How long does authorisation last?

Each consent lasts up to 180 days. After that the cardholder simply re-approves access to keep the sync running.

Do I need my own PSD2 licence or certificate?

No. open-banking.io provides the certificate-free, compliant access layer, so you connect Opelkortet with just an API key.
