Trøgstad Sparebank open banking and API access

Trøgstad Sparebank is an independent Norwegian savings bank, and open-banking.io lets you reach its account data without wrestling with eIDAS certificates or PSD2 licences. As a certificate-free service covering 2,600+ banks across the EU and UK, it gives individuals and developers a single, private way to pull balances and transactions from Trøgstad Sparebank. Because it is zero-knowledge, your financial data is decrypted locally with an encryption key that only you hold — open-banking.io's servers only ever store your public key.

How to connect Trøgstad Sparebank

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key involved in linking your bank:

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated on your own device, so nobody else can read your data.
  2. In the dashboard, pick Trøgstad Sparebank and choose the account type you need — both business and personal accounts are supported.
  3. You are redirected to Trøgstad Sparebank's own secure login, where you approve access under PSD2. This consent lasts up to 180 days, after which you simply re-approve.
  4. Your accounts sync straight into your open-banking.io dashboard, ready to view.

Note that Trøgstad Sparebank has no published BIC/SWIFT code in our directory, so selecting it by name in the dashboard is the reliable route.

Access your data

Once Trøgstad Sparebank 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 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 — so an API key alone only ever yields ciphertext. The CLI and SDK read and sync existing connections; they never connect a bank.

All of this costs around EUR 3/month.

Does open-banking.io need a certificate or licence?

No. It is certificate-free — you connect Trøgstad Sparebank straight through the bank's own consent screen.
