Merkur Andelskasse API Access & Open Banking Data

Merkur Andelskasse is Denmark's values-based cooperative bank, and open-banking.io lets you reach its account data without certificates, eIDAS registration, or a licence of your own. Whether you hold a personal account or run finances through a business account, you approve a single PSD2 consent and your balances and transactions flow into one place — encrypted so that only you can read them.

Unlike raw bank APIs, there is nothing to register with a regulator and no per-bank onboarding. open-banking.io covers 2,600+ EU and UK institutions, and Merkur Andelskasse is one of them.

How to connect Merkur Andelskasse

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 keys are generated locally on your own device, so no one else — not even open-banking.io — can decrypt what you sync.
  2. In the dashboard, search for Merkur Andelskasse and choose your account type: business or personal.
  3. You are redirected to Merkur Andelskasse's own secure login, where you approve access on the bank's consent screen (standard PSD2 authorisation).
  4. Your accounts sync back into the dashboard. The consent lasts up to 180 days, after which you simply re-approve.

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 with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. Without that private key an API key returns only ciphertext — the servers never hold anything readable.

Merkur Andelskasse does not publish a BIC through this integration, so selection is by name in the dashboard rather than by BIC.

The whole service runs about EUR 3/month, with zero-knowledge, certificate-free access built in.

Do I need an eIDAS certificate to access Merkur Andelskasse?

No. open-banking.io handles the regulated connection; you only approve consent on the bank's own screen.

Can I connect a Merkur Andelskasse account with the CLI?

No. Connecting is done in the dashboard. The CLI, SDK and API only read and sync connections that already exist.

Who can decrypt my Merkur Andelskasse data?

Only you. Data is decrypted locally with your private key; open-banking.io stores just your public key.
