Bankinter API Access — Connect Spanish Accounts

Bankinter is one of Spain's established banks, and open-banking.io lets you pull its account data into your own apps, dashboards or bookkeeping tools without touching screen-scraping or storing customer credentials. Once a customer authorises access, their Bankinter data flows through a single, standard REST endpoint — the same interface you'd use for any of the 2,600+ European and UK banks we cover.

How to connect Bankinter

  1. Sign up for an open-banking.io account and grab your API key.
  2. Call the endpoint listing supported institutions and select Bankinter (BIC BKBKESMMXXX).
  3. Redirect your user to Bankinter's own authorisation screen to approve access.
  4. Receive the returned consent token and start requesting data straight away.

No eIDAS certificates, no bank-specific onboarding, no PSD2 licence of your own required.

What data you can access

  • Accounts — both personal and business account types are supported.
  • Balances — current and available figures in near real time.
  • Transactions — historical and incoming movements for reconciliation, analytics or categorisation.

Bankinter connections honour the PSD2 standard, and a single customer authorisation stays valid for up to 180 days before it needs renewing. That long consent window means fewer re-authentication prompts and smoother recurring syncs for your users.

Privacy by design

our platform is zero-knowledge: your users' banking credentials go only to Bankinter, never to us, and we don't retain them. Because the service is certificate-free, you skip the costly QWAC/QSealC setup that traditional PSD2 integrations demand. You get clean data access while the sensitive parts stay where they belong.

Pricing

Flat and predictable — around EUR 3 per month, with no per-call surprises or enterprise minimums. Test in a sandbox first, then scale to production on the same key.

Does connecting Bankinter require my own bank licence?

No. open-banking.io acts as the regulated access layer, so you can integrate Bankinter without holding a PSD2 authorisation yourself.

How often can I refresh Bankinter data?

As often as you need within the active consent period. A single approval lasts up to 180 days before the customer re-authorises.

Can I access both personal and business accounts?

Yes. Both account types are available through the same endpoint once the account holder grants consent.
