Betri API Access & Open Banking | open-banking.io

Betri serves customers across the Faroe Islands within the Danish Realm, and open-banking.io lets you reach its account data without certificates, sandbox registration, or a bank-grade eIDAS setup. It is a zero-knowledge service: an encryption key is generated on your own device, so your Betri balances and transactions are decrypted locally and never readable by open-banking.io's servers, which hold only your public key. For roughly EUR 3 per month you get standardised PSD2 access to Betri alongside 2,600+ other European banks.

Betri supports both business and personal account types. There is no BIC on file for this connection, and each authorisation lasts up to 180 days before Betri asks you to renew consent.

How to connect Betri

Connecting happens entirely in the open-banking.io dashboard — no code, endpoint, or API key is involved. First, sign up and set an encryption passphrase; this generates your personal keys on your device. Next, open the dashboard, pick Betri from the bank list, and choose whether you are linking a business or personal account. open-banking.io then redirects you to Betri's own secure login, where you approve access on the bank's PSD2 consent screen. Once Betri confirms, your selected accounts sync straight into your dashboard, ready to view.

Access your data

Reading Betri data programmatically is an optional step you take after the connection exists. On the Developers page, create an API key and export a credentials.json file — it bundles that 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 directly. Every request carries your key in the X-Api-Key header, and each response is decrypted locally with your private key. An API key by itself only ever returns ciphertext, which keeps the whole flow zero-knowledge. Note that the CLI and SDK read and sync existing connections only — they never create one.

Does open-banking.io need a certificate for Betri?

No. There are no eIDAS certificates and no bank sandbox onboarding. You connect through Betri's normal login and consent screen.

Can open-banking.io read my Betri transactions?

No. Data is decrypted on your device with a key only you hold, so the service sees ciphertext only.

How long does Betri access last?

Up to 180 days per consent. After that, Betri prompts you to reauthorise from the dashboard.
