CaixaBank API Access: Connect Spanish Bank Data

Pulling live data out of CaixaBank no longer means wrestling with bank-specific portals or PSD2 certificate paperwork. With open-banking.io you connect once and stream CaixaBank account information straight into your own software — accounting tools, treasury dashboards, reconciliation jobs or personal finance apps. One integration covers CaixaBank (BIC CAIXESBBXXX) alongside 2,600+ other banks across the EU and UK.

How to connect CaixaBank

1. Create an open-banking.io account and grab your API key.
2. Call the connect endpoint and select CaixaBank as the institution.
3. Redirect the account holder to CaixaBank's own login to approve access — you never see their credentials.
4. Receive the authorised token and begin fetching data through the unified API.

What data you can access

Once a CaixaBank connection is authorised, you can read:

• Accounts — IBANs, account type and holder metadata for both business and personal profiles.
• Balances — current and available amounts, refreshed on demand.
• Transactions — booked and pending entries with amounts, dates, counterparties and reference details.

Consent and coverage

CaixaBank supports both business and personal accounts through the API. A single consent stays valid for up to 180 days, after which the account holder simply re-authorises to keep the feed alive. The same request shape works for every other bank on the network, so scaling from one Spanish account to a pan-European portfolio needs no new code.

Privacy by design

open-banking.io is zero-knowledge: authentication happens directly between the customer and CaixaBank, and we never store banking passwords. There are no eIDAS or QWAC certificates to buy, host or renew — that whole compliance layer is handled for you, so a small team can ship a bank integration in an afternoon.

Pricing

Access starts at roughly EUR 3 per month — flat and predictable, with no per-call surprises or enterprise minimums. The same subscription unlocks every bank in the catalogue.

Is CaixaBank included in the network?

Yes. CaixaBank (BIC CAIXESBBXXX) is fully supported for both business and personal accounts.

Do I need my own PSD2 licence or certificate?

No. open-banking.io operates the regulated, certificate-free layer, so you only handle the API.

How often must consent be renewed?

CaixaBank consent lasts up to 180 days; the customer re-approves after that to continue syncing.
