Sydbank API Access for Danish Bank Account Data

Pulling your Sydbank data into your own systems no longer means chasing eIDAS certificates or negotiating a direct bank integration. With open-banking.io, you connect once and start syncing Sydbank account information through a single, consistent REST API — the same interface that covers 2,600+ banks across the EU and UK.

How to connect Sydbank

  1. Create an open-banking.io account and grab your API key.
  2. Call the endpoint to initiate a Sydbank connection.
  3. Redirect the account holder to Sydbank's secure login to approve access.
  4. Receive the callback and begin reading account data straight away.

No client certificates, no lengthy onboarding, no per-bank paperwork.

What data you can access

Once consent is granted, Sydbank exposes the essentials for both business and personal accounts:

  • Accounts — identifiers, currency and account metadata.
  • Balances — live and booked balance figures.
  • Transactions — dated entries with counterparties, amounts and references.

Note that a BIC is not returned for Sydbank via this connection, so build your account matching around the IBAN and account identifiers instead.

Sydbank consent lasts up to 180 days before the account holder needs to re-authorise. That maximum window keeps re-consent prompts infrequent while staying inside Danish and EU PSD2 rules. Coverage spans Sydbank's retail and business customers in Denmark.

Privacy by design

open-banking.io runs on a zero-knowledge model: credentials are entered only on Sydbank's own login screen, never on our side, and we hold no copy of your banking passwords. Because the platform is certificate-free, you skip the cost and renewal cycle of QWAC/QSEAL certificates entirely while remaining PSD2-compliant.

Pricing

Access starts at roughly EUR 3 per month — a flat, predictable fee that includes Sydbank alongside every other bank on the network. No setup charges, no per-call surprises.

FAQ

Do I need a Danish TPP licence to use Sydbank?

No. open-banking.io operates under its own regulated permissions, so you can read Sydbank data without holding your own licence or certificates.

How current is the transaction data?

Balances and transactions are fetched on demand, so each call reflects what Sydbank reports at that moment — ideal for reconciliation and cash-flow views.

Can I connect several Sydbank accounts?

Yes. Each account holder authorises separately, and you can maintain many active Sydbank connections under one open-banking.io key.
