Sparkasse Witten API Access via open-banking.io

Bringing Sparkasse Witten account data into your own software no longer means wrestling with eIDAS certificates or bank-specific SDKs. open-banking.io gives you a single, uniform API to read your Sparkasse Witten accounts, keep balances current, and pull transaction history on a schedule you control.

Whether you are reconciling business books or building a personal money dashboard, the same integration covers both personal and business accounts held at Sparkasse Witten (BIC WELADED1WTN).

How to connect Sparkasse Witten

  1. Create an open-banking.io account and generate an API key.
  2. Start an authorisation request that targets Sparkasse Witten.
  3. You are redirected to the bank's own login to approve access — your credentials stay with the bank.
  4. Receive a consent token and begin calling the API for your accounts.
  5. Refresh the synced data as often as your workflow needs, within the active consent window.

What data you can access

  • Accounts — identifiers, account type, and holder details for personal and business accounts.
  • Balances — up-to-date booked and available amounts.
  • Transactions — historical and incoming entries with counterparties, dates, and references.

A single consent to Sparkasse Witten stays valid for up to 180 days before the bank requires re-authorisation. open-banking.io reaches this bank as part of a network of more than 2,600 banks across the EU and UK, so adding further institutions later uses the exact same code path.

Privacy by design

The platform is zero-knowledge: your banking login is entered only at Sparkasse Witten's own site, never with us. There are no eIDAS or QWAC certificates to buy, provision, or renew — the certificate-free model removes the heaviest part of PSD2 onboarding while keeping your data flowing directly to you.

Pricing

Access starts at roughly EUR 3 per month, with no per-certificate fees and no enterprise contract required to begin.
