Raiffeisenbank Grimma API Access & Open Banking

open-banking.io gives you a private, standards-based way to reach your Raiffeisenbank Grimma accounts across the EU and UK. Whether you hold a personal current account or run business banking with this Saxony cooperative bank (BIC GENODEF1GMR), you can link it once and keep your balances and transactions flowing into a single dashboard — without certificates, screen-scraping, or handing anyone a copy of your data. Everything is decrypted on your own device with a key that never leaves it.

How to connect Raiffeisenbank Grimma

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 locally, so only you can later unlock the data.
  2. In the dashboard, search for Raiffeisenbank Grimma and choose the account type you need — business or personal.
  3. You are redirected to Raiffeisenbank Grimma's own secure login, where you approve access under PSD2 consent. Your credentials are entered only on the bank's screen.
  4. Once approved, your accounts sync into the dashboard. Consent lasts up to 180 days, after which you simply re-approve.

Access your data

After a connection exists, developers can optionally read it programmatically. From the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. Then use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read or sync connections you already made in the dashboard — they never create one.

Because open-banking.io is zero-knowledge, its servers hold only your public key and store your data as ciphertext. An API key alone returns unreadable data without your private key. All of this runs for around EUR 3/month, certificate-free.

Is my Raiffeisenbank Grimma login shared with open-banking.io?

No. You authenticate only on Raiffeisenbank Grimma's own consent screen; open-banking.io never sees your banking password.

Can I connect a business account?

Yes. Both business and personal Raiffeisenbank Grimma accounts (BIC GENODEF1GMR) are supported.

How long does access last?

Each consent is valid for up to 180 days, then you re-approve from the dashboard.
