NatWest Group exposes an open banking API built on the UK Open Banking standard, covering account information (AIS), payment initiation (PIS) and confirmation of funds (CBPII). Beyond the regulated UK Open Banking baseline it also offers 7 premium API categories: real-time balances, statement reporting, bulk payments, cross-border & high-value, payment tracking, FX & hedging and confirmation of payee.
Access uses OAuth 2.0 with redirect SCA, over a REST interface. A self-service sandbox lets you build and test before you apply for production access.
The API serves the United Kingdom. BankSnipe rates NatWest Group's API maturity 5/5 (Mature), last reviewed 9 Jun 2026.

NatWest Group API: frequently asked questions
Does NatWest Group have a public API?
Yes. NatWest Group 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://www.bankofapis.com.
Does NatWest Group offer an API sandbox?
Yes. The sandbox is self-service, so you can sign up and start calling it without a commercial agreement in place. It is at https://developer.sandbox.natwest.com.
Which open banking standard does the NatWest Group API use?
UK Open Banking: the API standard mandated for UK banks. 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 NatWest Group 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 NatWest Group offer premium APIs beyond PSD2?
Yes. We have recorded 7 premium categories on NatWest Group: real-time balances, statement reporting, bulk payments, cross-border & high-value, payment tracking, FX & hedging and confirmation of payee. These sit above the regulated UK Open Banking baseline and are the ones corporate treasury teams tend to care about.
Which countries does the NatWest Group API cover?
the United Kingdom.
Is the NatWest Group 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 NatWest Group 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 UK Open Banking baseline.
