Arquia Bank API Access for Accounts & Transactions

Pull live financial data from Arquia Bank into your own product without wrestling with certificates or per-bank integrations. open-banking.io gives you a single EU/UK API endpoint that speaks to Arquia Bank (BIC CASDESBBXXX) alongside 2,600+ other institutions, so syncing Spanish account data becomes a routine call rather than a project.

Whether you are building accounting automation, a treasury dashboard, or a personal finance app, the same request pattern works across every connected bank. Onboard Arquia Bank once and reuse the flow everywhere.

How to connect Arquia Bank

  1. Create an open-banking.io account and grab your API key.
  2. Start an authorisation session, selecting Arquia Bank as the target institution.
  3. Redirect the account holder to Arquia Bank to approve access — they log in with their own credentials, never sharing them with you.
  4. Receive the consent token and begin fetching data through the unified endpoints.

What data you can access

Once consent is granted, you can retrieve:

  • Accounts — identifiers and metadata for both business and personal account types.
  • Balances — current and available amounts, refreshed on demand.
  • Transactions — dated, categorised movement history for reconciliation and analysis.

Arquia Bank permits a maximum consent window of 180 days, after which the account holder simply re-authorises to keep the connection live. Both business and personal accounts are in scope, so mixed-portfolio use cases are covered from a single integration.

Privacy by design

open-banking.io is zero-knowledge: credentials go straight to Arquia Bank, and we never see or store them. There are no eIDAS certificates to buy, renew, or manage — the compliance overhead sits with us, not you. You handle data, not secrets.

Pricing

A flat subscription of roughly EUR 3 per month covers Arquia Bank access and the full 2,600+ bank network. No setup fees, no per-call surprises.

FAQ

Do I need my own banking licence to use this?

No. open-banking.io operates as the licensed intermediary, so you connect to Arquia Bank through our regulated infrastructure.

How often can I refresh Arquia Bank data?

Balances and transactions can be pulled on demand throughout the active consent period, up to the 180-day maximum before renewal.

Are business and personal accounts both supported?

Yes. Arquia Bank exposes both business and personal account types, and both are reachable through the same API.
