Sparbanken Västra Mälardalen Open Banking Access

Reaching account data from Sparbanken Västra Mälardalen no longer means wrangling eIDAS certificates or running your own PSD2 stack. open-banking.io links this Swedish savings bank into a single dashboard covering 2,600+ EU and UK institutions, and every figure that lands in front of you is decrypted on your own device with a key that never leaves it.

The service is certificate-free and zero-knowledge: open-banking.io stores only your public key, so its servers can hold your Sparbanken Västra Mälardalen data but never read it. Both business and personal accounts are supported, and a single PSD2 consent stays valid for up to 180 days before you re-approve.

How to connect Sparbanken Västra Mälardalen

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 open-banking.io and set an encryption passphrase. Your key pair is generated locally on your device from that passphrase.
  2. In the dashboard, pick Sparbanken Västra Mälardalen (BIC SWEDSESS) and choose the account type — business or personal.
  3. You are redirected to Sparbanken Västra Mälardalen's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Once approved, your accounts sync back into the dashboard, ready to view. The consent lasts up to 180 days.

Access your data

Programmatic access is an optional step for developers, taken only after the bank is connected. From 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 you can 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 each response is decrypted locally with your own key. An API key on its own only ever returns ciphertext — without your private key there is nothing readable to see.

All of this runs on a flat subscription of roughly EUR 3 per month, with no per-call fees or certificate renewals.

Do I need an eIDAS certificate for Sparbanken Västra Mälardalen?
