Vestjysk Bank Open Banking & Secure API Access

Reaching your Vestjysk Bank accounts programmatically usually means TPP licences, eIDAS certificates and a stack of PSD2 paperwork. open-banking.io removes all of that. It gives you a single dashboard to link your Danish bank and, when you're ready, a clean developer path to read the same data — without ever handing your financial history to a third party. Everything you pull down is decrypted on your own machine with a key only you hold.

Vestjysk Bank is covered for both business and personal account types, identified by BIC VEHODK22, with a maximum consent lifetime of 180 days before you re-approve access.

How to connect Vestjysk Bank

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 encryption keys are generated locally on your device, so nobody else — not even open-banking.io — can reconstruct them.
  2. In the dashboard, search for Vestjysk Bank and choose whether you're linking a business or personal account.
  3. You're redirected to Vestjysk Bank's own secure login, where you approve access on the bank's PSD2 consent screen. Your credentials only ever touch the bank.
  4. Once approved, your Vestjysk Bank accounts and transactions sync straight into your dashboard, ready to view.

The consent stays valid for up to 180 days, after which you simply repeat the approval.

Access your data

Once a connection exists, developers can optionally read it in code. 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.
  • Or call the REST API / an SDK, authenticating with the X-Api-Key header.

Every response arrives encrypted and is decrypted locally with your own key. The CLI and SDK only read and sync connections you've already made in the dashboard — they never establish new ones. An API key on its own returns nothing but ciphertext without your private key.

This is the zero-knowledge, certificate-free model: open-banking.io holds only your public key and can never read your Vestjysk Bank data. All of it — 2,600+ EU/UK banks — costs around EUR 3/month.

Do I need an eIDAS certificate?

No. open-banking.io handles the regulated connection, so you skip TPP licences and certificates entirely.

Can open-banking.io see my transactions?

No. Data is decrypted only on your device with a key it never holds — it's zero-knowledge by design.

How do I connect a Vestjysk Bank account in code?

You don't — connecting is a dashboard-only step. The CLI, SDK and API only read existing connections.
