Vimmerby Sparbank API Access & Open Banking Data

Vimmerby Sparbank serves the Kalmar County community in southeastern Sweden, and open-banking.io lets you reach its account and transaction data without the usual PSD2 bureaucracy. There are no eIDAS certificates to buy, no bank sandbox to register with, and no compliance paperwork. You link your Vimmerby Sparbank accounts once, and the platform keeps them synced under encryption that only you can undo. Both business and personal accounts are supported, identified by BIC SWEDSESS.

The defining trait is the zero-knowledge design. When you sign up, an encryption key is generated on your own device from a passphrase you choose. open-banking.io stores only your public key, so its servers physically cannot read or decrypt your Vimmerby Sparbank data — the plaintext exists only where you decrypt it.

How to connect Vimmerby Sparbank

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

  1. Create an open-banking.io account and set your encryption passphrase; your keys are generated locally on your device.
  2. In the dashboard, search for Vimmerby Sparbank and choose the account type you need — business or personal.
  3. You are redirected to Vimmerby Sparbank's own secure login, where you approve access under PSD2 (consent lasts up to 180 days before you renew it).
  4. Control returns to your dashboard and your accounts sync in automatically.

Because approval takes place on the bank's own consent screen, your credentials are never seen or handled by open-banking.io.

Access your data

Programmatic access is an optional step you take after connecting. On the Developers page, create an API key and export a credentials.json — it bundles that API key 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; without your private key, nobody — including the servers — can read it.

All of this runs at roughly EUR 3/month across 2,600+ supported European banks.

Do I need a developer certificate for Vimmerby Sparbank?

No. open-banking.io is certificate-free — you approve access on the bank's consent screen and skip eIDAS entirely.

Up to 180 days. When it expires, simply reauthorize Vimmerby Sparbank from the dashboard.

Can open-banking.io see my transactions?

No. It holds only your public key, so your data stays encrypted until you decrypt it locally.
