WiZink API Access — Connect Spain Accounts | Open Banking

Bring your WiZink account data into any app or workflow through a single open-banking connection. open-banking.io links directly to WiZink (Spain, BIC POPLESMMXXX) so you can read balances and pull transaction history without maintaining your own PSD2 stack, eIDAS certificates, or per-bank integrations. Whether you are building a dashboard, reconciling ledgers, or feeding an analytics pipeline, the WiZink data flows through one consistent REST interface.

How to connect WiZink

  1. Create an account at open-banking.io and grab your API key.
  2. Call the endpoint listing supported institutions and select WiZink (Spain).
  3. Redirect the account holder to WiZink's own login, where they approve access using their normal bank credentials.
  4. Receive the callback with an active consent token.
  5. Query accounts, balances, and transactions as structured JSON.

What data you can access

  • Accounts — identifiers, currency, and metadata for personal and business WiZink accounts.
  • Balances — current and available amounts, refreshed on demand.
  • Transactions — dated, categorized entries with counterparty details and references.

WiZink supports both personal and business account types. Each authorization stays valid for up to 180 days before the customer needs to re-approve, so long-running syncs keep working without weekly friction. WiZink is one of 2,600+ banks reachable through the same API, meaning you can add other institutions later without rewriting a line of code.

Privacy by design

open-banking.io is zero-knowledge: we relay authenticated requests without holding a copy of the account holder's banking credentials, and there are no eIDAS or QWAC certificates for you to buy, install, or renew. Consent is explicit, revocable, and always granted at WiZink itself.

Pricing

One flat subscription of roughly EUR 3 per month covers WiZink alongside the full network. No per-call surcharges, no setup fee, no certificate costs.

Do I need a PSD2 licence to use this?

No. open-banking.io provides the regulated access layer, so you connect to WiZink through our infrastructure without holding your own licence or certificates.

How often can I refresh WiZink data?

You can pull fresh balances and transactions whenever your app needs them, within a single consent that lasts up to 180 days before renewal.

Does this work for business accounts?

Yes. WiZink exposes both personal and business account types, and both are available through the same endpoints.
