Postbank Bulgaria API Access & Open Banking Data

Reaching your Postbank (Bulgaria) account data used to mean eIDAS certificates, sandbox registration and bespoke PSD2 plumbing. open-banking.io removes all of that. It is a certificate-free, zero-knowledge gateway to 2,600+ EU and UK banks, so pulling balances and transactions from Postbank becomes a matter of a few clicks in a dashboard — no bank-specific integration to build and maintain.

Postbank (BIC BPBIBGSF) is covered for both business and personal accounts, and a single approval keeps your access live for up to 180 days before it needs renewing under PSD2 rules.

How to connect Postbank

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code snippet or key involved in this step.

  1. Sign up for open-banking.io and set your encryption passphrase. Your cryptographic keys are generated on your own device, so only you can later unlock the data.
  2. In the dashboard, choose Postbank and select the account type you want to link — business or personal.
  3. You are redirected to Postbank's own secure login, where you authenticate and approve the access request (the standard PSD2 consent screen).
  4. Once approved, your Postbank accounts sync straight into your open-banking.io dashboard and refresh automatically.

That is the whole flow. You never hand credentials to open-banking.io — the approval lives on Postbank's side.

Access your data

Reading Postbank data programmatically is an optional step you take after the connection exists. On the Developers page, create an API key and export a credentials.json, which bundles that key 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 API key alone only ever returns ciphertext. The CLI and SDK read and sync existing connections; they never create one.

All of this runs on a zero-knowledge model: open-banking.io stores only your public key and can never read your accounts. Pricing is a flat ~EUR 3/month.

Do I need an eIDAS certificate for Postbank?

No. open-banking.io is certificate-free — you approve access directly on Postbank's login screen.

Can open-banking.io see my Postbank transactions?

No. Data is decrypted on your device with a key only you hold; the servers store just your public key.

No. Postbank consent is valid for up to 180 days, after which you re-approve access.
