Sydbank API Access for Germany | Open Banking

Pulling live financial data from Sydbank in Germany no longer means wrestling with per-bank integrations or eIDAS certificates. With open-banking.io you connect once and stream Sydbank account information straight into your product, spreadsheet, or ledger — keeping balances and transactions continuously in sync without manual exports.

Sydbank operates under BIC SYBKDE22XXX, and our API reaches it the same way it reaches 2,600+ other institutions across the EU and UK: through a single, consistent interface.

How to connect Sydbank

  1. Create an open-banking.io account and grab your API key.
  2. Start a connection session and select Sydbank (Germany) using BIC SYBKDE22XXX.
  3. Choose the account type you need — business or personal.
  4. Redirect the account holder to Sydbank's secure login to approve access.
  5. Receive your access token and begin reading account data immediately.

What data you can access

Once consent is granted, you can retrieve:

  • Accounts — identifiers, currency, and metadata for connected business and personal accounts
  • Balances — current and available balances, refreshed on demand
  • Transactions — booked and pending entries with dates, amounts, and counterparties

Sydbank supports a maximum consent window of 180 days, after which the account holder simply re-authorises to keep the connection alive. Both business and personal account types are covered, so you can serve individuals and companies through the same endpoints.

Privacy by design

We built open-banking.io to be zero-knowledge: your users' credentials go directly to Sydbank and never touch our servers. There are no eIDAS or QWAC certificates to buy, renew, or manage — we handle the regulatory plumbing so you focus on your product. Data flows encrypted, end to end.

Pricing

One flat plan of roughly EUR 3 per month unlocks Sydbank alongside every other supported bank. No per-connection fees, no certificate costs, no enterprise minimums.
