Poštová banka Open Banking & API Access Guide

Poštová banka is one of Slovakia's established retail banks, and open-banking.io lets you reach its account and transaction data without wrangling PSD2 certificates or eIDAS setup. The service covers 2,600+ banks across the EU and UK, and Poštová banka is one of them — both business and personal account types are supported, with a consent window of up to 180 days before you re-authorise. No BIC is required on our side to get started.

What makes this different is the trust model. open-banking.io is zero-knowledge: your encryption keys are generated on your own device from a passphrase only you know, and our servers only ever hold your public key. Even we cannot read your Poštová banka data.

How to connect Poštová banka

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 private key is created locally, in your browser, and never leaves your device.
  2. In the dashboard, search for Poštová banka and choose the account type you want to link (business or personal).
  3. You are redirected to Poštová banka's own secure login, where you approve access on the bank's PSD2 consent screen — your credentials go straight to the bank, never to us.
  4. Once approved, your accounts and transactions sync into your dashboard automatically. The consent stays valid for up to 180 days.

Access your data

Reading your data programmatically is an optional step for developers, only after the connection above exists. On 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 you can 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 alone only ever returns ciphertext.

All of this runs at roughly EUR 3/month.

Do I need an eIDAS certificate for Poštová banka?

No. open-banking.io is certificate-free — you never handle a QWAC or QSEALC to reach Poštová banka.

Yes. Poštová banka supports both business and personal account types; pick the one you need when connecting in the dashboard.

Can the CLI connect my bank for me?

No. The CLI and SDKs only read and sync connections that already exist — there is no connect command. Linking Poštová banka always happens in the dashboard.
