Langå Sparekasse API Access & Open Banking Data

Langå Sparekasse is a small, community-rooted Danish savings bank in Langå, and open-banking.io gives you a clean, EU-compliant way to reach its account data without wrestling with bank-specific PSD2 plumbing. There are no eIDAS certificates to buy, no sandbox onboarding, and no per-bank credentials to juggle — you set one encryption passphrase, connect the bank once, and your balances and transactions sync into a dashboard that only you can decrypt.

Both business and personal Langå Sparekasse accounts are supported, and access consent lasts up to 180 days before Langå Sparekasse asks you to re-approve — the standard PSD2 renewal window. Langå Sparekasse has no BIC published in our directory, but you never need one: you select the bank by name inside open-banking.io.

How to connect Langå Sparekasse

Connecting happens entirely in the open-banking.io dashboard — there is no API call, key, or code 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 — ever holds them.
  2. In the dashboard, search for Langå Sparekasse and choose the account type you want to link (business or personal).
  3. You are redirected to Langå Sparekasse's own secure login, where you approve access on the bank's consent screen. Your credentials stay with the bank.
  4. Once approved, your accounts and transactions sync back into your dashboard, ready to view and refresh.

Access your data

Reading the data programmatically is an optional step you take after connecting. On the Developers page, create an API key and export a credentials.json — it bundles that API key together with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request carries your key in the X-Api-Key header, and each response is decrypted locally with your private key. Because open-banking.io is zero-knowledge and holds only your public key, an API key alone returns nothing but ciphertext — the data only becomes readable on your machine. The CLI and SDK read and sync existing connections; they never connect a bank themselves.

At around EUR 3/month, you get certificate-free access with local-only decryption across 2,600+ EU and UK banks.
