Landessparkasse Oldenburg API Access via Open Banking

Pull live financial data from Landessparkasse zu Oldenburg (LzO, BIC SLZODE22XXX) straight into your own product or tooling. open-banking.io gives you a single, PSD2-compliant gateway to sync LzO account information without wrestling with per-bank onboarding, eIDAS certificates, or bespoke sandbox contracts. Whether you are building a bookkeeping integration, a treasury dashboard, or a personal-finance app, the connection behaves the same as it does for every other bank on the network.

How to connect Landessparkasse Oldenburg

1. Create an open-banking.io account and grab your API key.
2. Select Landessparkasse zu Oldenburg from the German bank catalogue.
3. Redirect the account holder to LzO's secure login to grant consent.
4. Receive tokens and begin polling the accounts, balances, and transactions endpoints.

No screen-scraping, no stored banking passwords — authorisation happens directly on the bank's own SCA screens.

What data you can access

• Accounts — IBANs, currency, and product metadata for both business and personal LzO accounts.
• Balances — booked and available amounts, refreshed on demand.
• Transactions — dated, categorised movement history for reconciliation and analytics.

Consent and coverage

A single LzO consent stays valid for up to 180 days before the customer needs to re-authorise, so long-running syncs keep flowing with minimal friction. Both business and personal account types are supported. Beyond LzO, the same integration reaches 2,600+ banks across the EU and UK, so adding the next institution is a config change, not a new project.

Privacy by design

open-banking.io is zero-knowledge and certificate-free. We never see or hold your users' bank credentials, and you don't need to obtain or manage your own QWAC/eIDAS certificates — the platform handles the regulated plumbing while your data stays yours.

Pricing

Flat and predictable: roughly EUR 3 per month. No per-call surprises, no enterprise minimums to get started.

FAQ

Do I need my own PSD2 licence to connect to LzO?

No. open-banking.io operates the regulated access layer, so you can consume Landessparkasse Oldenburg data without holding a licence or certificates yourself.

Can I access both business and personal LzO accounts?

Yes. Both account types are supported through the same endpoints once the account holder grants consent.

How often do I need to renew consent?

LzO consent lasts up to 180 days. After that window the customer simply re-authorises through the bank's login to keep the connection active.
