GrønlandsBANKEN API Access & Open Banking Data

Reaching your GrønlandsBANKEN (BANK of Greenland) data no longer means wrestling with eIDAS certificates or a bank sandbox. open-banking.io gives individuals and developers a single, private route to Greenland-based account and transaction data across 2,600+ EU/UK banks. Everything is decrypted on your own device with a key only you hold — so the data flows to you, not through a third party that can read it.

GrønlandsBANKEN supports both business and personal account types, and a single approval grants a consent window of up to 180 days before you renew. GrønlandsBANKEN does not publish a BIC in our directory, but you never need one — you select the bank by name inside the dashboard.

How to connect GrønlandsBANKEN

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 an open-banking.io account.
  2. Set your encryption passphrase. Your keys are generated locally on your device, so nobody else — not even open-banking.io — can decrypt what you sync.
  3. In the dashboard, pick GrønlandsBANKEN and choose the account type you want to link (business or personal).
  4. You are redirected to GrønlandsBANKEN's own secure login and consent screen, where you approve access directly with the bank under PSD2.
  5. Your accounts flow back into the dashboard and begin syncing.

Access your data

Once 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 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 every response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, the payload stays unreadable.

The service is certificate-free and zero-knowledge by design, at roughly EUR 3/month.

Do I need a developer account to use GrønlandsBANKEN?

No. Connecting and viewing accounts is a dashboard task. API keys and credentials.json are only for the optional programmatic read step.

Can the CLI connect my bank for me?

No. The CLI and SDKs only read or sync connections that already exist. There is no connect command — linking always happens in the dashboard via GrønlandsBANKEN's consent screen.

Can open-banking.io staff see my GrønlandsBANKEN transactions?

No. The servers hold only your public key. Data is decrypted on your device, so ciphertext is all that ever leaves your control.
