Bundesbank API Access: Connect German Accounts

Pulling live data from Bundesbank into your own tools no longer means wrestling with bank-specific integrations. open-banking.io gives you a single, standardised connection to Bundesbank (BIC MARKDEFFXXX) alongside 2,600+ other institutions across the EU and UK. Authorise once, and account information flows straight into your app, dashboard, or reconciliation workflow.

How to connect Bundesbank

  1. Create an open-banking.io account and select Bundesbank from the German bank directory.
  2. Choose the account you want to link — both business and personal account types are supported.
  3. Confirm the connection inside Bundesbank's own secure login, granting read access.
  4. Receive an access token and begin syncing data through a single REST endpoint.

No eIDAS certificates, no per-bank onboarding paperwork, no sandbox scavenger hunt — the same call shape works for every bank on the network.

What data you can access

Once a consent is active, you can retrieve:

  • Accounts — IBANs, account identifiers, currency, and holder details
  • Balances — current and available amounts, refreshed on demand
  • Transactions — dated entries with counterparties, references, and amounts for statements and categorisation

A single Bundesbank authorisation stays valid for up to 180 days before the account holder needs to renew it, so you can run long-lived syncs without constant re-prompting. Coverage spans personal and business Bundesbank accounts, and the same integration extends to thousands of banks should you need to onboard customers elsewhere.

Privacy by design

open-banking.io is zero-knowledge: credentials are handled by the bank's own authentication flow, and we never store the login secrets that would let anyone impersonate an account holder. The platform is certificate-free, removing the operational burden and cost of managing PSD2 certificates yourself while keeping every request encrypted end to end.

Pricing

Access starts at roughly EUR 3 per month — a flat, predictable rate that covers Bundesbank and the full network, with no setup fees or hidden per-call surcharges.

FAQ

Is a PSD2 certificate required to connect Bundesbank?

No. open-banking.io is certificate-free, so you skip eIDAS certificate procurement entirely and connect through the standard API.

How often can I refresh Bundesbank balances and transactions?

As often as your use case needs within an active consent. Each authorisation remains valid for up to 180 days before renewal.

Yes. Both account types are supported through the same connection flow and endpoints.
