Fibank API Access & Open Banking Data in Bulgaria

Need programmatic access to your First Investment Bank (Fibank) accounts? open-banking.io lets you reach your Fibank balances and transactions across the EU under PSD2 — without certificates, eIDAS setup, or a bank sandbox. Fibank (BIC FINVBGSF) supports both business and personal accounts, and a single consent stays valid for up to 180 days before you re-approve.

Everything is zero-knowledge: your data is encrypted on your own device with a key only you hold, so open-banking.io servers store nothing they could ever read.

How to connect Fibank

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

1. Sign up and set an encryption passphrase. Your keys are generated locally on your device.
2. In the dashboard, pick Fibank from the bank list and choose your account type — business or personal.
3. You are redirected to Fibank's own secure login, where you approve access on the bank's PSD2 consent screen.
4. Your Fibank accounts sync back into your dashboard, ready to view.

That's it — the account holder always approves directly with Fibank, never through a third-party redirect.

Access your data

Once Fibank is connected, developers can optionally read the data 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 you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API.

Every request sends the X-Api-Key header, and each response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, nobody (not even open-banking.io) can read it. The CLI and SDK read and sync existing connections; they never connect a bank themselves.

All of this runs for around EUR 3/month, covering 2,600+ EU and UK banks.

FAQ

Do I need an eIDAS certificate to access Fibank?

No. open-banking.io is certificate-free. You approve access on Fibank's consent screen and your keys are generated on your device — there is nothing to register with a QTSP.

How long does my Fibank consent last?

Up to 180 days. After that, you simply re-approve access from the dashboard to keep your Fibank data syncing.

Can open-banking.io read my Fibank transactions?

No. The service is zero-knowledge and holds only your public key. Data is decrypted locally with a private key that never leaves your device.
