Connect to Westra Wermlands Sparbank API Access

Pulling live data from Westra Wermlands Sparbank (BIC SWEDSESS) into your own systems no longer means wrestling with eIDAS certificates or bespoke bank integrations. With open-banking.io you point a single REST endpoint at the bank and start syncing Westra Wermlands Sparbank account information almost immediately — whether the accounts are personal or business.

The bank, headquartered in Arvika, Värmland, is reachable through the same unified API that already covers 2,600+ institutions across the EU and UK, so the code you write here is the code you reuse everywhere else.

What data you can access

  • Accounts — IBANs, currency, holder details and account metadata.
  • Balances — current and available figures, refreshed on demand.
  • Transactions — booked and pending entries with counterparties, dates and references.

Access is authorised under PSD2 with a maximum consent window of 180 days, after which the account holder simply re-approves. Both business and personal accounts at Westra Wermlands Sparbank are supported through the same flow.

Privacy by design

The platform is zero-knowledge — your customers' credentials go straight to the bank, never to us, and we don't store the financial data flowing through. There are no QWAC/QSEAL certificates to purchase, register or renew; the certificate-free architecture removes the heaviest part of PSD2 onboarding.

Pricing

Flat, predictable access for roughly EUR 3 per month — no per-call surprises and no separate certificate fees.

FAQ

Is a bank-issued certificate required?

No. open-banking.io is certificate-free, so you skip eIDAS QWAC/QSEAL setup entirely.

Can I read both business and personal accounts?

Yes. Westra Wermlands Sparbank exposes both account types, and each is linked through the same consent flow.

How often can I refresh transactions?

As often as your workflow needs within the active consent; renew every 180 days to keep syncing.
