Sparkasse Dortmund API Access via Open Banking

Pull live Sparkasse Dortmund account data into your own app, spreadsheet, or accounting stack without scraping or screen-mirroring. open-banking.io gives you a single, standards-based connection to Sparkasse Dortmund (BIC DORTDE33XXX) alongside 2,600+ other banks across the EU and UK, so a Dortmund current account and a bank in Lisbon or London answer to the same integration.

Once a customer approves access, balances and transactions stay in sync automatically for the life of the consent — no repeated manual exports, no proprietary bank plug-ins to maintain.

How to connect Sparkasse Dortmund

  1. Create an open-banking.io account and grab your API key.
  2. Call the bank-search endpoint and select Sparkasse Dortmund (BIC DORTDE33XXX).
  3. Redirect the account holder to Sparkasse Dortmund's own login and strong-customer-authentication screen.
  4. Receive the consent token and start reading account, balance, and transaction data through the unified API.

What data you can access

  • Accounts — business and personal account details and identifiers (IBAN, currency, product type).
  • Balances — current and available balances, refreshed on demand.
  • Transactions — booked and pending entries with amounts, counterparties, dates, and remittance text.

Sparkasse Dortmund supports both business and personal accounts. A single customer authorisation can stay valid for up to 180 days before re-consent is required, keeping long-running syncs stable while remaining within PSD2 rules. One credential set spans every supported bank, so adding more institutions later needs no new integration work.

Privacy by design

open-banking.io is zero-knowledge: your users' banking data passes through without us retaining it, and there are no eIDAS certificates for you to buy, register, or renew. You focus on your product; the compliance and connectivity plumbing is handled.

Pricing

Access starts at roughly EUR 3 per month — flat, predictable, and far below the cost of building and certifying a direct bank connection yourself.

Is a Sparkasse Dortmund business account supported?

Yes. Both business and personal Sparkasse Dortmund accounts can be connected through the same API.

How long does access last before renewal?

Each approved consent remains active for up to 180 days, after which the account holder simply re-authenticates.

Do I need my own bank certificate?

No. open-banking.io is certificate-free, so you skip eIDAS setup entirely and connect straight away.
