Bremer LB API Access & Open Banking Integration

Reaching your Bremer LB account data no longer means wrestling with eIDAS certificates, sandbox registrations, or bespoke bank APIs. open-banking.io gives you PSD2 access to Bremer LB (BIC BRLADE22XXX) through a single dashboard, covering both business and personal accounts. Every balance and transaction is encrypted the moment it leaves the bank and decrypted only on your own device with a key that never leaves your hands.

That zero-knowledge design is the point: open-banking.io stores only your public key, so its servers can never read your Bremer LB statements. You get one consistent workflow across 2,600+ European banks for roughly EUR 3/month, with no certificate paperwork to renew.

How to connect Bremer LB

Connecting happens entirely in the open-banking.io dashboard — there is no code, endpoint, or API 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 at this moment.
  2. In the dashboard, search for Bremer LB and choose the account type you need — business or personal.
  3. You are redirected to Bremer LB's own secure login, where you approve access on the bank's PSD2 consent screen. Your credentials stay with the bank.
  4. Your approved accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve.

Access your data

Once Bremer LB is connected, reading the data programmatically is an optional developer step. Open the Developers page, create an API key, and export a credentials.json — this bundles the API key together with your private decryption key.

With that file you can run the CLI (openbanking accounts, openbanking transactions, openbanking sync), call the REST API, or use an SDK. Requests authenticate with 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 data stays unreadable, which is exactly what keeps the system zero-knowledge.

Do I need an eIDAS certificate for Bremer LB?

No. open-banking.io is certificate-free. You approve access directly on Bremer LB's consent screen — nothing to install or register.

Can open-banking.io read my Bremer LB transactions?

No. Data is encrypted to your public key and only your device holds the private key, so the servers store ciphertext they cannot decrypt.

How often do I re-authorise?

Bremer LB permits consent windows of up to 180 days. When one expires, re-approve in the dashboard to resume syncing.
