Sparkasse UnnaKamen API Access | open-banking.io

Need programmatic access to Sparkasse UnnaKamen accounts? open-banking.io lets you pull live account data from Sparkasse UnnaKamen (BIC WELADED1UNN) through a single REST API — no eIDAS certificates, no bank-by-bank integration work. Whether you are building bookkeeping automation, cash-flow dashboards or reconciliation tooling, you can sync Sparkasse UnnaKamen data the same way you would reach any of the 2,600+ banks on our network.

How to connect Sparkasse UnnaKamen

  1. Create an open-banking.io account and generate your API key.
  2. Call the institutions endpoint and select Sparkasse UnnaKamen (BIC WELADED1UNN).
  3. Redirect the account holder to Sparkasse UnnaKamen's own login to approve consent.
  4. Receive the callback and start requesting data — accounts are available immediately.

What data you can access

  • Accounts — IBANs, product names and currency for personal and business accounts.
  • Balances — current and available balances, refreshed on demand.
  • Transactions — booked and pending entries with counterparties, amounts, dates and remittance details.

Sparkasse UnnaKamen supports both personal and business accounts. A single consent stays valid for up to 180 days before the account holder needs to re-authorise, so long-running syncs keep working without repeated prompts. Coverage runs through the same unified endpoints used across every institution on the platform.

Privacy by design

open-banking.io is zero-knowledge: credentials are entered only on Sparkasse UnnaKamen's own authentication screens, never on ours, and we do not store your banking passwords. The API is certificate-free, so you skip the cost and overhead of maintaining QWAC/QSEAL certificates yourself.

Pricing

One flat rate of roughly EUR 3/month covers API access — no per-bank fees and no per-call surcharges as you scale.
