Hello Bank API Access — Sync Accounts in Minutes

Hello Bank is BNP Paribas' French digital bank, and open-banking.io lets you pull its account data into your own app, spreadsheet or accounting tool without wrestling with PSD2 certificates or bespoke integrations. One API call reaches Hello Bank alongside 2,600+ other European banks, so you sync once and keep every balance current.

How to connect Hello Bank

  1. Create an open-banking.io account and grab your API key.
  2. Start an authorization session, selecting Hello Bank (BIC BNPAFRPPXXX).
  3. Send your customer to Hello Bank's own login to approve access.
  4. Receive the consent token and start reading data — no extra setup required.

What data you can access

Once a customer consents, you can retrieve:

  • Accounts — business and personal account details and identifiers.
  • Balances — live and booked balances across each account.
  • Transactions — categorised transaction history for reconciliation and analytics.

Hello Bank supports both business and personal accounts. A single approval stays valid for up to 180 days, after which the customer simply re-authorizes — no repeated prompts in between, which keeps long-running dashboards and bookkeeping flows uninterrupted.

Privacy by design

open-banking.io is zero-knowledge: your customers' credentials go straight to Hello Bank and never touch our servers. There are no eIDAS or QWAC certificates to buy, host or renew — the platform handles the regulated plumbing so you handle the data.

Pricing

Access costs roughly EUR 3 per month, flat. No per-call surcharges, no enterprise minimums — the same rate whether you connect one Hello Bank account or scale across the full 2,600-bank network.

FAQ

Does open-banking.io store my Hello Bank login?

No. Credentials are entered only on Hello Bank's authentication page. The zero-knowledge design means we never see or retain them.

Can I connect both business and personal Hello Bank accounts?

Yes. Both account types are supported through the same flow, so mixed portfolios work without separate integrations.

Each authorization lasts up to 180 days. Before it lapses, prompt the customer to reconnect and data access resumes immediately.
