Trøndelag Sparebank API Access & Open Banking

Trøndelag Sparebank, the Eika-alliance local bank serving Kyrksæterøra and the wider Trøndelag region, keeps your account and transaction history behind its own secure login. open-banking.io gives you a single, private route to that data — whether you hold a personal account or run a business — without certificates, screen-scraping, or a bank-by-bank integration project.

Because open-banking.io is zero-knowledge, your Trøndelag Sparebank data is encrypted on your own device and decrypted only with a key that never leaves you. The service stores just your public key, so nobody at open-banking.io — or anywhere else — can read your statements. It is one of 2,600+ EU and UK banks reachable through the same dashboard for around EUR 3 per month.

How to connect Trøndelag Sparebank

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 generated locally on your device from that passphrase.
  2. In the dashboard, search for and select Trøndelag Sparebank, then choose whether you are linking a business or personal account.
  3. You are redirected to Trøndelag Sparebank's own secure login and consent screen, where you approve access under PSD2.
  4. Your accounts sync back into the dashboard. The consent you grant lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Reading the data programmatically is an optional step for developers, and only after the connection above exists. 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key — an API key on its own only ever returns ciphertext. Note that Trøndelag Sparebank publishes no BIC, so identify accounts by IBAN.

Do I need an API key to connect the bank?

No. Connecting is done in the dashboard via Trøndelag Sparebank's consent screen. API keys are only for reading data afterwards.

Can open-banking.io see my Trøndelag Sparebank balances?

No. Data is decrypted on your device with a key only you hold; the servers keep only your public key.

How long does access last?

Each consent is valid for up to 180 days, then you renew it on the bank's login screen.
