Sparbanken i Karlshamn API Access & Open Banking

Sparbanken i Karlshamn (BIC SWEDSESS) is a Swedish savings bank serving Blekinge, and open-banking.io gives you a clean, standards-based way to reach your account data there. Instead of wrestling with PSD2 certificates or eIDAS onboarding, you connect once through a dashboard and get both personal and business accounts flowing into a place you control. Every byte is encrypted with a key that never leaves your device, so nobody — not even us — can read what your Sparbanken i Karlshamn accounts contain.

How to connect Sparbanken i Karlshamn

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

  1. Sign up for open-banking.io and set an encryption passphrase. Your keys are generated locally on your own device.
  2. In the dashboard, pick Sparbanken i Karlshamn and choose the account type you want to link — business or personal.
  3. You are redirected to Sparbanken i Karlshamn's own secure login and consent screen, where you approve access under PSD2.
  4. Once approved, your accounts sync back into your dashboard. A single consent stays valid for up to 180 days, after which you simply re-approve.

That's the whole flow: authorise on the bank's side, watch the accounts appear on yours.

Access your data

Reading the data programmatically is an optional developer step you take after the bank is connected. Open 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 directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. An API key on its own only ever returns ciphertext, which is exactly the point.

All of this runs for around EUR 3/month, with no certificate paperwork.

Do I need a PSD2 certificate for Sparbanken i Karlshamn?

No. open-banking.io is certificate-free — you approve access on Sparbanken i Karlshamn's own consent screen and we handle the rest.

Can open-banking.io see my Sparbanken i Karlshamn balances?

No. The service is zero-knowledge and holds only your public key. Data is decrypted on your device with a private key only you have.

Does the CLI connect my bank for me?

No. The CLI and SDK only read and sync connections that already exist. Connecting Sparbanken i Karlshamn always happens in the dashboard.
