Vadstena Sparbank API Access & Open Banking Data

Vadstena Sparbank serves customers around Vadstena and the wider Östergötland region, and open-banking.io lets you reach your accounts there under PSD2 without certificates, eIDAS onboarding, or a bank-specific integration project. Whether you hold a personal account or run a business, you get a single dashboard where your Vadstena Sparbank balances and transactions land already synced and ready to use. The service covers 2,600+ EU and UK banks, and everything is decrypted locally with a key that never leaves your device — open-banking.io only ever holds your public key, so it cannot read your data.

How to connect Vadstena Sparbank

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

  1. Sign up for open-banking.io and set an encryption passphrase. Your key pair is generated right there on your own device.
  2. In the dashboard, search for Vadstena Sparbank (BIC SWEDSESS) and choose the account type you need — business or personal.
  3. You are redirected to Vadstena Sparbank's own secure login and consent screen, where you approve access directly with the bank.
  4. Your accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve.

Because approval happens on the bank's own page, your credentials are never seen by open-banking.io.

Access your data

Once Vadstena Sparbank is connected, developers can optionally read the data programmatically. On the Developers page, create an API key and export a credentials.json — this bundles your 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. Every request sends the X-Api-Key header, and each response is decrypted locally with your own key — the API key alone only ever returns ciphertext. All of this sits inside the ~EUR 3/month subscription.

Is a certificate or license required?

No. open-banking.io is certificate-free. You sign up, set a passphrase, and approve access on Vadstena Sparbank's consent screen — nothing else.

Can open-banking.io see my transactions?

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

Do the CLI and SDK connect the bank?

No. They only read and sync connections you already approved in the dashboard. There is no connect command.
