Banco Mediolanum API Access — Spain Open Banking

Pull your Banco Mediolanum data into your own systems without wrestling with bank-specific integrations. open-banking.io gives you a single, unified API to read account details, balances and transaction history from Banco Mediolanum in Spain, so your app, spreadsheet or accounting tool always reflects the latest movements. One connection, one JSON format, no PSD2 certificates to obtain or maintain.

  2. Call the connection endpoint and select Banco Mediolanum (BIC BFIVESBBXXX) from the Spanish bank list.
  3. Choose the account type you need to link — personal or business.
  4. You are redirected to Banco Mediolanum to log in and approve access with the bank's own strong authentication.

What data you can access

  • Accounts — IBANs, currency, product type and holder details.
  • Balances — current and available balances, refreshed on demand.
  • Transactions — dated entries with amounts, counterparties and reference text for reconciliation and analytics.

Each authorisation from Banco Mediolanum stays valid for up to 180 days, after which the account holder simply re-approves. Both personal and business accounts are supported. Banco Mediolanum is one of 2,600+ banks reachable through the same open-banking.io API, so adding institutions across the EU and UK never means a new integration.

Privacy by design

open-banking.io is zero-knowledge: credentials go straight to the bank and are never seen or stored by us. There are no eIDAS or QWAC certificates for you to purchase, install or renew — we handle the regulated PSD2 plumbing so you only handle clean data.

Pricing

Flat and predictable: around EUR 3 per month. No per-call surcharges, no setup fees, no enterprise sales call to get started.

Do I need a PSD2 certificate to connect Banco Mediolanum?

No. open-banking.io is certificate-free — the licensing and technical requirements are covered on our side.

How long does Banco Mediolanum access last before renewal?

Consent runs for up to 180 days per approval, then the account holder reauthorises through the bank.

Can I connect both personal and business accounts?

Yes. Banco Mediolanum supports personal and business account types through the same API flow.
