DKM Darlehnskasse Münster API & Open Banking Access

Need programmatic, privacy-first access to your DKM Darlehnskasse Münster accounts? open-banking.io lets you link the bank once and then read balances and transactions on your own terms. It covers 2,600+ EU and UK banks, requires no eIDAS certificate, and is built around a zero-knowledge model: your data is decrypted locally with a key only you hold, so open-banking.io's servers only ever store your public key and ciphertext. DKM Darlehnskasse Münster (BIC GENODEM1DKM) is supported for both business and personal accounts, with consent lasting up to 180 days before you renew.

How to connect DKM Darlehnskasse Münster

Connecting happens entirely in 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 on your own device, so nobody else can reconstruct it.
  2. In the dashboard, pick DKM Darlehnskasse Münster and choose your account type — business or personal.
  3. You are redirected to DKM Darlehnskasse Münster's own secure login to approve access under PSD2 consent. Your credentials stay with the bank.
  4. Once approved, your accounts sync into the dashboard, and DKM Darlehnskasse Münster keeps that consent valid for up to 180 days.

Access your data

After the connection exists, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this 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 directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally on your machine. An API key on its own only returns ciphertext; without your private key it stays unreadable — which is exactly what makes the model zero-knowledge. The CLI and SDK only read and sync existing connections; there is no connect command.

All of this runs for around EUR 3/month.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free, so you skip the usual PSD2 licensing overhead entirely.

Can open-banking.io read my DKM Darlehnskasse Münster data?

No. Decryption happens locally with your key; the servers hold only your public key and encrypted data.
