Sparbanken Tranemo Open Banking & API Access | open-banking.io

Sparbanken Tranemo is a local Swedish savings bank, and open-banking.io lets you reach its account data without certificates, eIDAS licences or PSD2 red tape. We support Sparbanken Tranemo (BIC SWEDSESS) for both personal and business accounts, and everything you sync is decrypted locally with an encryption key that only you hold. open-banking.io is genuinely zero-knowledge: our servers store only your public key, so we can never read your balances or transactions.

With one subscription (~EUR 3/month) you get access to 2,600+ EU and UK banks, including Sparbanken Tranemo, through a single dashboard and an optional developer toolkit.

How to connect Sparbanken Tranemo

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 an open-banking.io account.
  2. Set your encryption passphrase. Your keys are generated on your own device, so your private decryption key never leaves it.
  3. In the dashboard, pick Sparbanken Tranemo and choose the account type (personal or business).
  4. You are redirected to Sparbanken Tranemo'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 into your dashboard, ready to view.

Access your data

Once Sparbanken Tranemo is connected, developers can optionally read the data programmatically. On the Developers page, create an API key and export a credentials.json — this bundles your 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.

Every request authenticates with the X-Api-Key header, and each response is decrypted locally with your own key. An API key alone only ever returns ciphertext — without your private key, the data stays unreadable. The CLI and SDK read and sync existing connections; they never create the bank connection itself.

Do I need an eIDAS certificate for Sparbanken Tranemo?

No. open-banking.io is certificate-free. You approve access on Sparbanken Tranemo's own consent screen — no licence or certificate required.

Can open-banking.io see my Sparbanken Tranemo transactions?

No. The service is zero-knowledge. Data is decrypted only on your device with a key we never receive.

How often do I re-authorise?

Sparbanken Tranemo consent is valid for up to 180 days. When it expires, reconnect from the dashboard in a few clicks.
