Sparbanken Boken API Access & Open Banking Data

Reaching your Sparbanken Boken accounts programmatically shouldn't mean chasing eIDAS certificates or standing up your own PSD2 gateway. open-banking.io gives you a single, privacy-first path to Sparbanken Boken (BIC SWEDSESS) covering both business and personal account types. Your data is decrypted locally with a key only you hold, so the service itself never sees a readable balance or transaction.

How to connect Sparbanken Boken

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 open-banking.io and set an encryption passphrase. Your encryption keys are generated right there on your own device.
  2. In the dashboard, pick Sparbanken Boken from the bank list and choose the account type you need (business or personal).
  3. You're redirected to Sparbanken Boken's own secure login, where you approve access under PSD2 consent — your credentials only ever touch the bank.
  4. Your accounts sync straight back into your dashboard, ready to view.

Consent lasts up to 180 days, after which you simply re-approve on Sparbanken Boken's screen to keep the connection live.

Access your data

Once a 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 together with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key there is nothing readable to leak.

Because the platform is zero-knowledge and certificate-free, it holds only your public key. That's the whole model, and it costs roughly EUR 3/month across 2,600+ supported banks.

Can I connect Sparbanken Boken with just an API key?

No. Bank connections are made in the dashboard by approving access on Sparbanken Boken's own login. API keys are only for reading data you've already connected.

What does the X-Api-Key actually return?

Encrypted data. Responses are decrypted on your machine with the private key in your credentials.json, so open-banking.io never sees plaintext.

Up to 180 days per PSD2 rules. Re-approve on the bank's consent screen to renew.
