Westra Wermlands Sparbank API Access & Open Banking

Reach your Westra Wermlands Sparbank accounts through a single, privacy-first service. open-banking.io links to this Värmland savings bank (BIC SWEDSESS) under PSD2, covering both business and personal accounts, so you can pull balances and transactions without wrestling with eIDAS certificates or bespoke bank integrations. It sits alongside 2,600+ other EU and UK institutions on one platform.

The defining trait is zero-knowledge design. Your encryption keys are generated on your own device from a passphrase you choose, and every piece of account data is decrypted locally. open-banking.io's servers only ever hold your public key — they cannot read or reconstruct your Westra Wermlands Sparbank information, even in principle.

How to connect Westra Wermlands 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 your encryption passphrase. Your private key never leaves your device.
  2. In the dashboard, search for Westra Wermlands Sparbank and choose the account type you need (business or personal).
  3. You are redirected to Westra Wermlands Sparbank's own secure login, where you approve access on the bank's consent screen.
  4. Your approved accounts sync back into your dashboard. Consent lasts up to 180 days, after which you simply re-approve.

Access your data

Reading data programmatically is an optional developer step you take after the connection exists. 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 carry the X-Api-Key header, and each response is decrypted locally with your own key. An API key alone returns only ciphertext — without your private key, no one, including open-banking.io, can read it.

Pricing is roughly EUR 3/month for the whole platform.

Does open-banking.io store my banking credentials?

No. You authenticate directly on Westra Wermlands Sparbank's login page, and only encrypted data you control ever reaches the service.

Can I connect a Westra Wermlands Sparbank account with the CLI?

No. The CLI and SDK only read and sync existing connections. Connecting is done in the dashboard.

How long does access stay active?

Up to 180 days per consent, then you re-approve from the dashboard.
