Mittelbrandenburgische Sparkasse Potsdam Open Banking

Want a single, private view of your Mittelbrandenburgische Sparkasse in Potsdam accounts? open-banking.io links the Potsdam Sparkasse (BIC WELADED1PMB) to a zero-knowledge dashboard where every balance and transaction is decrypted on your own device with a key only you hold. It covers 2,600+ EU and UK banks, needs no eIDAS certificate, and costs around EUR 3/month.

Both business and personal account types are supported, and a single authorisation stays valid for up to 180 days before Mittelbrandenburgische Sparkasse in Potsdam asks you to renew it.

How to connect Mittelbrandenburgische Sparkasse in Potsdam

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 key pair is generated locally on your device, so open-banking.io only ever stores your public key.
  2. In the dashboard, search for Mittelbrandenburgische Sparkasse in Potsdam and choose whether you are linking a business or personal account.
  3. You are redirected to Mittelbrandenburgische Sparkasse in Potsdam's own secure login, where you approve access under PSD2.
  4. Once you confirm, your accounts sync straight into your dashboard — ready to browse.

The Sparkasse handles the login itself; open-banking.io never sees your banking credentials.

Access your data

Want the data in your own tools? That is an optional developer step that comes after the connection exists. On the Developers page, create an API key and export a credentials.json — it bundles the API key together with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — they cannot create one.

Because open-banking.io is zero-knowledge, an API key alone returns only ciphertext; without your private key the data stays unreadable — even to the servers holding it.
