Sparkasse Mittelholstein AG API Access | Open Banking

Programmatically access Sparkasse Mittelholstein Aktiengesellschaft account data through open-banking.io, a single EU/UK open-banking API covering 2,600+ banks. Instead of building a direct PSD2 integration for this Rendsburg-based savings bank, you sync accounts, balances and transactions through one consistent, developer-friendly interface.

Whether you are automating bookkeeping, powering a personal-finance dashboard or reconciling company ledgers, open-banking.io handles the heavy lifting of consent, authentication and data normalisation for both business and personal accounts at Sparkasse Mittelholstein.

• Balances — real-time booked and available amounts.
• Transactions — historical and incoming entries with counterparty, amount and reference fields.

Consent and coverage

Sparkasse Mittelholstein supports both business and personal account access. A single consent stays valid for up to 180 days, after which the account holder simply re-authorises — so long-running syncs need minimal user friction.

Privacy by design

open-banking.io is zero-knowledge and certificate-free. You never manage eIDAS certificates or QWAC/QSEAL keys, and sensitive credentials never pass through your servers. Data flows straight from the bank to your application under the user's explicit consent.

Pricing

Flat, predictable pricing from roughly EUR 3/month — no per-call surprises and no enterprise onboarding overhead.
