bunq API Access in Austria via open-banking.io

Looking to pull your bunq data into your own tools without wrestling with raw bank APIs? open-banking.io gives you a single, standardised gateway to bunq in Austria, so accounting apps, budgeting dashboards and internal systems can read live financial data through one clean integration.

bunq is a mobile-first European bank, and its accounts are reachable in Austria through the same open-banking framework we use for every other institution on our network. That means you write to one API and instantly gain access to bunq alongside 2,600+ other banks.

How to connect bunq

  1. Create an open-banking.io account and get your API key.
  2. Call our endpoint and select bunq (Austria) as the target institution.
  3. Redirect the account holder to bunq to approve access with their own credentials.
  4. Receive the secure token and begin querying data straight away.

What data you can access

  • Accounts: personal and business account details and identifiers
  • Balances: real-time and available balances per account
  • Transactions: dated transaction history with counterparties and references

bunq supports both personal and business account types through our connection. A single user consent stays valid for up to 180 days before the account holder needs to re-authorise, keeping long-running syncs stable with minimal friction. Note that a BIC is not published for this connection, so route via the institution selector rather than by BIC.

Privacy by design

open-banking.io is built on a zero-knowledge model: we never store your customers' banking credentials, and there are no eIDAS certificates for you to buy, register or renew. Authentication happens directly between the user and bunq, so sensitive data never sits with us.

Pricing

One flat subscription of roughly EUR 3/month covers your access — no per-call surcharges, no setup fees and no certificate overhead. Predictable cost, full coverage.

FAQ

Do I need my own open-banking licence to use bunq here?

No. You connect through open-banking.io's regulated infrastructure, so you skip the licensing and certificate requirements entirely.

How often can I refresh bunq transactions?

You can query as often as your app needs within the active consent window; each consent lasts up to 180 days before re-authorisation.

Can I connect bunq business accounts?

Yes. Both personal and business bunq accounts in Austria are supported through the same integration.
