OTP Bank API Access — Connect Hungary Accounts

Pulling live data from OTP Bank (BIC OTPVHUHBXXX) into your own tools no longer means wrestling with bank-specific integrations. open-banking.io gives you a single, standardized API to reach OTP Bank alongside 2,600+ other institutions across the EU and UK — so your app, spreadsheet, or accounting stack stays in sync with what actually happens in the account.

Whether you run a company treasury or manage personal finances, you connect once and read the data you need on demand.

How to connect OTP Bank

  1. Create your open-banking.io account and grab an API key.
  2. Call the endpoint to start a consent flow for OTP Bank.
  3. The account holder approves access through OTP Bank's own secure login (strong customer authentication).
  4. Receive the access token and begin querying accounts, balances, and transactions.

No eIDAS certificates, no sandbox paperwork, no waiting on a bank onboarding queue.

What data you can access

  • Accounts — identifiers and metadata for both business and personal accounts.
  • Balances — current and available amounts, refreshed on request.
  • Transactions — dated entries with counterparties, amounts, and references for reconciliation or analytics.

OTP Bank supports a maximum consent window of 180 days, after which the account holder simply re-authorizes. Both business and personal account types are covered. Because everything routes through one consistent schema, adding a second or twentieth Hungarian or European bank later takes no extra engineering.

Privacy by design

open-banking.io is zero-knowledge: we don't store your customers' banking credentials, and account data passes through without being retained for our own use. The service is certificate-free, removing the biggest technical hurdle most PSD2 integrations impose. You stay in control of what you fetch and when.

Pricing

Access starts at roughly EUR 3 per month — a flat, predictable cost with no per-call surprises and no enterprise contract required to begin.

FAQ

As often as you need within the active consent period. Balances and transactions are fetched on request, up to the 180-day consent limit.

Does this work for both company and private accounts?
