Markaryds Sparbank API Access & Open Banking

Reaching Markaryds Sparbank account data used to mean bank certificates, sandbox registrations and a pile of PSD2 paperwork. open-banking.io removes all of it. This local community bank (BIC SWEDSESS) is one of 2,600+ EU and UK institutions you can link through a single dashboard, giving you clean access to both business and personal accounts without ever touching a certificate.

Everything runs on a zero-knowledge design: your encryption keys are generated on your own device, and open-banking.io only ever holds your public key. Balances and transactions from Markaryds Sparbank are decrypted locally, so no server — not even ours — can read them.

How to connect Markaryds Sparbank

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

  1. Sign up for an open-banking.io account.
  2. Set an encryption passphrase. Your private key is generated locally from it and never leaves your device.
  3. In the dashboard, search for Markaryds Sparbank and choose whether you're linking a business or personal account.
  4. You're redirected to Markaryds Sparbank's own secure login, where you approve access on the bank's consent screen (standard PSD2). This consent lasts up to 180 days, after which you simply re-approve.
  5. Your accounts sync straight into your dashboard, ready to view.

Access your data

Once the connection exists, 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 every response is decrypted locally with your own key. An API key alone only ever returns ciphertext — the private key in credentials.json is what makes it readable. The CLI and SDK read and sync existing connections; they never connect a bank themselves.

All of this is included for roughly EUR 3/month.
