Connect OBOS-Banken: API Access via open-banking.io

Pull live OBOS-Banken data into your own tools without wrestling with eIDAS certificates or bespoke bank onboarding. open-banking.io gives you one consented, read-only connection to OBOS-Banken so accounting software, budgeting apps, treasury dashboards and internal reporting stay continuously in sync with the source.

Whether you hold a private account or run a housing company through OBOS-Banken, the same endpoints surface everything you need, refreshed on demand.

How to connect OBOS-Banken

1. Create an open-banking.io account and generate an API key.
2. Select OBOS-Banken from the supported institution list.
3. Redirect the account holder to OBOS-Banken to authenticate and approve access.
4. Receive the consent token and start querying accounts, balances and transactions.
5. Refresh whenever you need up-to-date figures — no re-integration work.

What data you can access

• Accounts — identifiers, currency and metadata for personal and business accounts.
• Balances — current and available balances in real time.
• Transactions — dated, categorised entries with counterparties and references for reconciliation and cash-flow analysis.

Consent and coverage

OBOS-Banken supports both business and personal account types. A single customer authorisation stays valid for up to 180 days before renewal, so you can keep long-running syncs alive without constant re-prompts. No BIC is required to route the connection — selecting the bank is enough. Beyond OBOS-Banken, the same API 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

The platform is zero-knowledge: your credentials and financial data are never mined, resold or retained beyond what the connection needs. There are no eIDAS or QWAC certificates to buy, host or rotate — authentication and compliance are handled for you, so a small team can integrate as easily as a large one.

Pricing

Flat, predictable access from ~EUR 3/month. No per-call surcharges or enterprise minimums standing between you and OBOS-Banken data.
