Caixacallosa API Access — Open Banking Integration

Pull live Caixacallosa data into your own systems without wrestling with a bank-specific integration. open-banking.io gives you one consistent REST API that reaches Caixacallosa alongside 2,600+ other banks across the EU and UK, so accounting tools, treasury dashboards and personal-finance apps can read account information straight from the source.

How to connect Caixacallosa

1. Create an open-banking.io account and grab your API key.
2. Call the institution endpoint and select Caixacallosa (BIC CCRIES2A105).
3. Redirect the account holder to Caixacallosa's own login to approve access — no certificates or manual paperwork on your side.
4. Receive the authorised token and start requesting data through the unified API.

What data you can access

Once consent is granted, both business and personal Caixacallosa accounts expose:

• Accounts — IBANs, account metadata and ownership details.
• Balances — current and available amounts, refreshed on demand.
• Transactions — booked and pending entries with counterparties, dates and references.

Everything arrives in the same normalised schema you use for every other bank, so you write your parsing logic once.

Consent and coverage

A single Caixacallosa authorisation stays valid for up to 180 days before the account holder needs to re-approve, keeping long-running syncs smooth. The same endpoints cover 2,600+ institutions, letting you onboard multi-bank customers without new integration work per bank.

Privacy by design

open-banking.io runs a zero-knowledge model: your credentials and data pass through without us building a shadow copy of your financial life. There are no eIDAS certificates to purchase, renew or install — authentication happens directly with Caixacallosa, and you keep control of the tokens.

Pricing

Access starts at roughly EUR 3 per month, a flat, predictable cost with no per-bank surcharges. Test against real endpoints and scale up only when your integration is ready for production.

FAQ

Do I need an eIDAS certificate for Caixacallosa?

No. open-banking.io is certificate-free — you authenticate through Caixacallosa's standard consent flow and never handle regulatory certificates yourself.

Can I connect both business and personal accounts?

Yes. Caixacallosa supports both account types through the same API, so mixed portfolios are handled with identical endpoints.

How often do I re-authorise?

Each consent lasts up to 180 days. Before it lapses, prompt the account holder to renew and your Caixacallosa sync continues uninterrupted.
