Barclays 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 3 premium API categories: real-time balances, statement reporting and instant payments.
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 is offered in the United Kingdom and Ireland. BankSnipe rates Barclays's API maturity 5/5 (Mature), last reviewed 2 Nov 2026.

Notes
Barclays' API Exchange publishes 31 APIs. The UK Open Banking set covers accounts and transactions, payment initiation, confirmation of funds, variable recurring payments, event notification and dynamic client registration, with a separate Irish set for Barclays Bank Ireland. Two corporate APIs sit beyond the baseline, covering balance and transaction reporting and real-time payment initiation for corporate, bank and PSP clients. The remainder is open data and a large Barclaycard block for retail card servicing. The catalogue publishes no FX or trade-finance API.
Barclays API: frequently asked questions
Does Barclays have a public API?
Yes. Barclays 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://developer.barclays.com.
Does Barclays 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.
Which open banking standard does the Barclays 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 Barclays 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 Barclays offer premium APIs beyond PSD2?
Yes. We have recorded 3 premium categories on Barclays: real-time balances, statement reporting and instant payments. These sit above the regulated UK Open Banking baseline and are the ones corporate treasury teams tend to care about.
Which countries does the Barclays API cover?
the United Kingdom and Ireland.
Is the Barclays 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 Barclays 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.
