Santander exposes an open banking API built on the Berlin Group NextGenPSD2 standard, covering account information (AIS), payment initiation (PIS) and confirmation of funds (CBPII). Beyond the regulated PSD2 baseline it also offers 3 premium API categories: statement reporting, bulk payments and cross-border & high-value.
Access uses OAuth 2.0 with redirect SCA, over a REST interface. A sandbox is available, though access is not self-service.
The API is offered in Spain, the United Kingdom, Portugal and Poland, and what is live differs by market (see the table below). BankSnipe rates Santander's API maturity 5/5 (Mature), last reviewed 9 Jun 2026.

Santander API: frequently asked questions
Does Santander have a public API?
Yes. Santander publishes regulated PSD2 open banking APIs covering account information (AIS), payment initiation (PIS) and confirmation of funds (CBPII), plus premium APIs beyond that baseline. Registration and documentation live on its developer portal at https://market.apis-i.redsys.es.
Does Santander offer an API sandbox?
Yes. Sandbox access is available but not self-service, so you go through the bank to get in.
Which open banking standard does the Santander API use?
Berlin Group NextGenPSD2: the most widely used European open-banking API standard. Two banks on the same standard can still differ in the details, so read the bank's own documentation before you build.
How do you authenticate with the Santander API?
OAuth 2.0, with redirect SCA for the customer consent step. Production access to the regulated endpoints also means registering as a licensed third-party provider with the bank.
Does Santander offer premium APIs beyond PSD2?
Yes. We have recorded 3 premium categories on Santander: statement reporting, bulk payments and cross-border & high-value. These sit above the regulated PSD2 baseline and are the ones corporate treasury teams tend to care about.
Which countries does the Santander API cover?
Spain, the United Kingdom, Portugal and Poland. The offering is not identical in every market, so check the per-country table on this page.
Is the Santander API free to use?
Banks generally do not charge licensed third-party providers for the regulated open banking endpoints, which is the point of the mandate. Premium APIs above that baseline are commercial products priced by the bank. BankSnipe does not track pricing, so confirm it with the bank.
How mature is the Santander API?
BankSnipe scores it 5 out of 5 (Mature). The score counts how many of the four product signals are live: AIS, PIS, CBPII and premium APIs beyond the regulated PSD2 baseline.
