Strømmen Sparebank Open Banking & API Access

Reaching your Strømmen Sparebank accounts through a single, privacy-first interface is what open-banking.io is built for. Rather than juggling scraping scripts or waiting on a bank sandbox, you link Strømmen Sparebank once and pull balances and transactions on demand. The service covers 2,600+ EU and UK banks, is certificate-free, and is zero-knowledge: your Strømmen Sparebank data is decrypted on your own device with a key only you hold. Both business and personal account types are supported, and a single PSD2 consent stays valid for up to 180 days before you renew it.

How to connect Strømmen 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 cryptographic keys are generated locally on your device, so no one else can read what syncs.
  2. In the dashboard, search for and select Strømmen Sparebank, then choose whether you're linking a business or personal account.
  3. You're redirected to Strømmen Sparebank's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Once approved, your accounts flow back into your dashboard and sync automatically. The consent lasts up to 180 days.

Access your data

After the connection exists, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this bundles the API key and 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. Strømmen Sparebank publishes no BIC in our directory, so identify accounts by their IBAN or the labels shown in your dashboard. Note: the CLI and SDK only read and sync existing connections — there is no connect command.

Pricing is roughly EUR 3/month, with no certificates to buy or renew.

Does open-banking.io ever see my Strømmen Sparebank data?

No. It stores only your public key. Everything is decrypted on your device, so the servers hold ciphertext they cannot read.

Can I connect Strømmen Sparebank from the CLI?

No. Connecting is a dashboard-only flow that redirects you to the bank's login. The CLI and API only read data after that link exists.

How long does access last?

Up to 180 days per consent. When it expires, reconfirm on Strømmen Sparebank's consent screen to keep syncing.
