Tatra banka API Access & Open Banking | open-banking.io

Reach your Tatra banka accounts through a single, privacy-first workspace. open-banking.io links to Tatra banka under PSD2 and pulls your balances and transaction history into one dashboard — while every record stays encrypted with a key that never leaves your device. It covers 2,600+ EU and UK banks, needs no eIDAS certificate, and starts at roughly EUR 3 per month.

Tatra banka supports both business and personal accounts, and a single approval keeps your access alive for up to 180 days before you renew. Tatra banka publishes no public BIC in our reference set, so open-banking.io routes you straight to the bank by name — no bank codes to hunt down.

How to connect Tatra banka

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

  1. Create your open-banking.io account and set an encryption passphrase. Your keys are generated locally on your own device at this step.
  2. In the dashboard, search for Tatra banka and choose whether you're linking a business or personal account.
  3. You're redirected to Tatra banka's own secure login, where you approve access on the bank's PSD2 consent screen — your credentials only ever touch the bank.
  4. Once approved, your accounts sync back into the dashboard and refresh for the duration of your 180-day consent.

Because open-banking.io is zero-knowledge, its servers only ever hold your public key. The data flowing in is decrypted locally, so nobody at open-banking.io can read your Tatra banka activity.

Access your data

After your connection is live, 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. An API key on its own only returns ciphertext — without your private key, the data stays unreadable. Note the CLI and SDK only read and sync existing connections; there is no connect command.

No. open-banking.io is certificate-free — no eIDAS or QWAC setup. Sign up, set a passphrase, and approve access on Tatra banka's screen.

Can open-banking.io see my Tatra banka transactions?

No. It's zero-knowledge and holds only your public key. Decryption happens on your device with a key only you control.

How long does one approval last?

Up to 180 days for Tatra banka. After that you simply re-approve on the bank's consent screen.
