Faster Andelskasse Open Banking & API Data Access

Faster Andelskasse — the Danish cooperative andelskasse trading as FasterOikos in Astrup near Skjern — issues no public developer portal, so pulling your own account and transaction history into a script has traditionally meant certificates and red tape. open-banking.io removes that. It gives you PSD2-grade access to your Faster Andelskasse data through one dashboard, and hands the cryptographic keys to you alone. Both business and personal account types are supported, and a single approval keeps data flowing for the full 180-day consent window before you renew.

Because open-banking.io is zero-knowledge and certificate-free, there is nothing to install on a bank server and no eIDAS certificate to buy. Your data is encrypted on your own device with a key our servers never see.

How to connect Faster Andelskasse

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 your encryption passphrase. Your key pair is generated locally on your device; we only ever hold your public key.
  2. In the dashboard, search for Faster Andelskasse and choose the account type you need (business or personal).
  3. You are redirected to Faster Andelskasse's own secure login, where you approve access on the bank's PSD2 consent screen using MitID.
  4. Control returns to the dashboard and your accounts sync in. Consent lasts up to 180 days.

Note that Faster Andelskasse has no BIC listed here, so simply pick it by name in the bank list.

Access your data

Reading the data programmatically is an optional developer step after the connection exists. On the Developers page, create an API key and export a credentials.json — it bundles the API key with your private decryption key. Then use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request sends the X-Api-Key header, and each response is decrypted locally with your own key. The CLI and SDK only read and sync existing connections — they cannot connect a bank, and an API key on its own returns nothing but ciphertext without your private key.

All of this runs from around EUR 3/month.

Does open-banking.io ever see my Faster Andelskasse balances?

No. It is zero-knowledge — data is decrypted on your device, and our servers hold only your public key.

Do I need a certificate or bank agreement?

No. It is certificate-free; you approve access directly on Faster Andelskasse's own login.

How long does access last?

Up to 180 days per consent, after which you re-approve in the dashboard.
