Häradssparbanken Mönsterås API & Open Banking Access

Reaching account data from Häradssparbanken Mönsterås normally means wrestling with PSD2 certificates, sandbox registrations and per-bank API quirks. open-banking.io removes all of that. It is a zero-knowledge, certificate-free gateway covering 2,600+ EU and UK banks, so a single account gives you a consistent way to view and export your Häradssparbanken Mönsterås balances and transactions. Your data is encrypted with a key generated on your own device and decrypted only there — the service never holds anything but your public key.

Häradssparbanken Mönsterås (BIC SWEDSESS) is supported for both business and personal account types, with PSD2 consent lasting up to 180 days before you renew it.

How to connect Häradssparbanken Mönsterås

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 your encryption passphrase. Your keys are created locally, so only you can ever unlock the data.
  2. In the dashboard, search for Häradssparbanken Mönsterås and choose whether you're linking a business or personal account.
  3. You're redirected to Häradssparbanken Mönsterås's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Control returns to your dashboard and your accounts sync automatically. The consent stays valid for up to 180 days.

Access your data

Want to pull the data programmatically? That's an optional step after the connection exists. Open 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 authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read and sync connections you've already approved — they never create one. Note that an API key on its own returns ciphertext; without your private key the data stays unreadable, even to open-banking.io.

All of this runs for roughly EUR 3/month, with no eIDAS certificate or bank developer contract required.

FAQ

No. Linking is done in the dashboard and approved on the bank's login screen. API keys are only for the optional programmatic export afterwards.
