Sparbanken Tanum API Access & Open Banking Data

Reaching your Sparbanken Tanum account data no longer means wrestling with PSD2 certificates or building bespoke bank integrations. open-banking.io gives you read access to Sparbanken Tanum (BIC SWEDSESS) across both business and personal accounts, and every figure that lands in your dashboard is decrypted on your own device with a key only you hold. We are zero-knowledge by design: our servers keep your public key and never see your balances or transactions in the clear.

Sparbanken Tanum is one of 2,600+ EU and UK banks reachable through a single subscription of roughly EUR 3/month — no per-connection fees, no eIDAS certificate to source, no compliance paperwork on your side.

How to connect Sparbanken Tanum

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 an open-banking.io account.
  2. Set your encryption passphrase. Your keys are generated locally on your device, so nobody else — including us — can decrypt what you sync.
  3. In the dashboard, pick Sparbanken Tanum and choose the account type you need (business or personal).
  4. You are redirected to Sparbanken Tanum's own secure login, where you approve access under PSD2. Your consent lasts up to 180 days, after which you simply re-approve.
  5. Your accounts sync back into the dashboard, ready to view.

Access your data

Once Sparbanken Tanum is connected, developers can optionally read the data programmatically. 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 directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. Without that private key, an API key alone returns only ciphertext — which is exactly the point of a zero-knowledge model.

Note that the CLI and SDK only read and sync connections that already exist; there is no connect command, because connecting always happens in the dashboard.

FAQ

Do I need a PSD2 certificate for Sparbanken Tanum?

No. open-banking.io is certificate-free — we handle the regulated access so you never touch eIDAS certificates.

Can open-banking.io read my Sparbanken Tanum transactions?

No. Data is encrypted with a key generated on your device. We only ever hold your public key, so we cannot decrypt your account information.

Up to 180 days per approval, in line with PSD2. When it expires, reconnect from the dashboard to renew.
