bunq API Access in Lithuania | open-banking.io

Pulling your bunq data into your own tools shouldn't mean maintaining a bank-specific integration. With open-banking.io you connect once and start syncing bunq account information across Lithuania through a single, standardised REST API — no eIDAS certificates, no bespoke onboarding, no per-bank engineering.

Whether you run a personal bunq account or a business one, the same endpoints return clean JSON you can drop straight into dashboards, accounting flows, or reconciliation jobs.

How to connect bunq

  1. Create an open-banking.io account and grab your API key.
  2. Call the institutions endpoint and select bunq for Lithuania (LT).
  3. Redirect the account holder to bunq's secure login to approve access.
  4. Receive the authorised connection reference back at your callback URL.
  5. Query accounts, balances, and transactions on demand.

What data you can access

  • Accounts — IBANs, currency, product type, and holder details.
  • Balances — current and available amounts in real time.
  • Transactions — booked and pending entries with counterparties, dates, and reference fields.

bunq authorisations under this connection last up to 180 days before the account holder needs to re-approve, so long-running syncs keep working without constant re-prompts. open-banking.io reaches 2,600+ banks across the EU and UK, meaning bunq can sit alongside every other institution your users hold — one API, one contract.

Privacy by design

The platform is zero-knowledge: credentials go straight to bunq and are never seen or stored by us. It's also certificate-free, removing the QWAC/QSEAL burden that usually gates PSD2 access. You get the data flow without the compliance overhead.

Pricing

Flat and predictable at around EUR 3/month — no setup fees and no per-call surprises, so testing bunq access costs almost nothing to start.

Is a BIC required to connect bunq?

No. bunq is selected directly from our institution list for Lithuania, so no BIC is needed to begin the flow.

Can I connect both personal and business bunq accounts?

Yes. Both personal and business bunq account types are supported through the same endpoints.

How often can I refresh bunq transactions?

As often as your use case needs within an active consent. Once the 180-day window lapses, the account holder simply re-authorises.
