Post Luxembourg API Access & Open Banking Data
Post Luxembourg (BIC CCPLLULL) offers current accounts to households and companies across the Grand Duchy, and open-banking.io lets you reach that account data without wrestling with eIDAS certificates or a bank sandbox. It is a zero-knowledge bridge to more than 2,600 European banks: your encryption keys are generated on your own device, and open-banking.io only ever holds your public key, so nobody at the service can read a single transaction.
You link Post Luxembourg entirely from the open-banking.io dashboard — there is no API call, code snippet, or key involved in the connection itself.
How to connect Post Luxembourg
- Sign up for open-banking.io and set your encryption passphrase. This generates your personal keys locally; keep the passphrase safe, because it is what decrypts your data.
- In the dashboard, search for Post Luxembourg and choose the account type you hold — both business and personal accounts are supported.
- You are redirected to Post Luxembourg's own secure login, where you approve access under PSD2. Your credentials only ever touch the bank.
- Once approved, your accounts sync back into the dashboard. A single consent lasts up to 180 days before Post Luxembourg asks you to renew it.
Access your data
Connecting is all you need for the dashboard view. If you want the data programmatically, head to the Developers page after connecting, create an API key, and export a credentials.json — this bundles the API key together with your private decryption key. From there the CLI (openbanking accounts, openbanking transactions, openbanking sync), the SDKs, and the REST API all read your existing connection. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. An API key alone only ever returns ciphertext; without your private key, the data stays unreadable — which is exactly what zero-knowledge means. There is no connect command in the CLI: linking a bank always happens in the dashboard.
At roughly EUR 3 per month, you get certificate-free access to Post Luxembourg and every other supported bank on one plan.
