Hamburger Sparkasse API Access via Open Banking

Bring your Hamburger Sparkasse (Haspa) data into any app, dashboard or bookkeeping tool through a single open-banking.io connection. Instead of building a bespoke PSD2 integration and managing eIDAS certificates yourself, you point one standardised API at Haspa and start syncing account information within minutes. Whether you run a Hamburg-based business or manage personal finances, the flow is the same clean, read-only feed.

How to connect Hamburger Sparkasse

  1. Create an open-banking.io account and open the connect dialog.
  2. Search for Hamburger Sparkasse (BIC HASPDEHHXXX) in the bank list.
  3. Choose the account type you hold — business or personal.
  4. Authenticate directly with Haspa using your own online-banking credentials and strong customer authentication.
  5. Approve the consent, and your accounts begin syncing to the API immediately.

What data you can access

Once linked, open-banking.io exposes your Haspa accounts (IBANs and metadata), real-time balances, and full transaction history. Everything is delivered read-only in a consistent JSON structure, so the shape of the data is identical across every bank you connect — no per-institution parsing required.

A single consent stays valid for up to 180 days before Haspa requires you to re-authenticate, in line with PSD2 rules. open-banking.io covers 2,600+ banks across the EU and UK, so once you have integrated Haspa you can add other institutions through the very same endpoints and credentials.

Privacy by design

The platform is zero-knowledge: your banking credentials are entered only with Haspa and are never stored or visible to open-banking.io. There are no eIDAS or QWAC certificates for you to purchase, provision or renew — that regulatory overhead is handled for you, leaving a simple API key on your side.

Pricing

Access starts at roughly EUR 3 per month, a flat, predictable cost with no setup fees and no per-call surprises — a fraction of what a direct licensed PSD2 connection would cost to build and maintain.

FAQ

Do I need my own PSD2 licence or certificate?

No. open-banking.io operates the regulated connection and certificates, so you only need an API key to reach Hamburger Sparkasse.

Can I connect both business and personal Haspa accounts?

Yes. Haspa supports both business and personal account types through the same consent flow.

How often must the connection be renewed?

Each consent lasts up to 180 days, after which you re-authenticate with Haspa to keep the data flowing.
