Erste Bank API Access (Hungary) | open-banking.io

Pull live Erste Bank Hungary data into your own systems without wrestling with bank-specific integrations. open-banking.io gives you a single, standardised gateway to Erste Bank, so business and personal account information flows straight into your app, spreadsheet or accounting stack. One API, one subscription, and no per-bank onboarding paperwork.

Erste Bank Hungary (BIC GIBAHUHBXXX) is one of 2,600+ institutions reachable through the same interface, which means the code you write for Erste works everywhere else too.

What data you can access

• Accounts — identifiers, IBANs and metadata for business and personal accounts
• Balances — current and available amounts, refreshed on demand
• Transactions — booked and pending entries with dates, counterparties and references

Consent and coverage

Erste Bank Hungary supports both business and personal account types. A single authorisation stays valid for up to 180 days, after which the customer simply re-approves. You handle the renewal flow once and reuse it across every connected bank.

Privacy by design

open-banking.io is zero-knowledge: we relay data between Erste and your application without reading or storing it. There are no eIDAS certificates to buy, no QWAC/QSEAL setup, and no compliance overhead on your side — the platform carries the regulatory weight so you can ship faster.

Pricing

Flat access from roughly EUR 3 per month. No setup fees, no per-call surcharges, and the same rate covers every supported institution.

FAQ

Do I need my own open-banking licence?

How long does an Erste consent last?

Up to 180 days per authorisation. When it expires, the account holder re-confirms access in a few taps and data resumes.

Can I read both company and private accounts?

Yes — Erste Bank Hungary exposes both business and personal accounts through the same endpoints.
