Sparkasse Mecklenburg-Strelitz Open Banking API

Getting a clear, programmatic view of your Sparkasse Mecklenburg-Strelitz finances no longer means wrestling with eIDAS certificates or a PSD2 sandbox. open-banking.io links your Neustrelitz-based Sparkasse account to a private dashboard and keeps every balance and transaction encrypted under a key that never leaves your device. It covers 2,600+ banks across the EU and UK, so your Sparkasse Mecklenburg-Strelitz accounts sit alongside the rest of your financial life in one place.

Whether you hold a personal current account or run a business relationship, the same secure route applies, and consent stays valid for up to 180 days before a quick renewal.

How to connect Sparkasse Mecklenburg-Strelitz

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key involved in this step.

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally on your own device.
  2. In the dashboard, search for Sparkasse Mecklenburg-Strelitz (BIC NOLADE21MST) and choose the account type you hold — business or personal.
  3. You are redirected to Sparkasse Mecklenburg-Strelitz's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync back into the dashboard, ready to view. The authorisation lasts up to 180 days.

Access your data

Reading your data in code is an optional step that comes only after the connection above exists. Open the Developers page, create an API key, and export a credentials.json file — this bundles the API key together with your private decryption key.

From there, the CLI works out of the box:

openbanking accounts
openbanking transactions
openbanking sync

You can also use an SDK or the REST API. Every request carries your key in the X-Api-Key header, and each response is decrypted locally on your machine. Because open-banking.io only ever holds your public key, its servers cannot read your data — an API key alone returns nothing but ciphertext without your private key.

Pricing and privacy

The service is zero-knowledge and certificate-free, priced at around EUR 3 per month.

Does open-banking.io store my banking password?

No. You authenticate directly on Sparkasse Mecklenburg-Strelitz's own login page; open-banking.io never sees your credentials.

Can I connect a business account?

Yes. Both business and personal Sparkasse Mecklenburg-Strelitz accounts are supported through the same dashboard flow.

How long does access last before I re-approve?

Up to 180 days, after which you re-confirm consent on the bank's screen.
