openapi: 3.1.0
info:
title: Product Details
description: The Barclays Product Details API allows users to discover various financial products Barclays offers. From
personal accounts to SME lending products, business current accounts to commercial credit cards, users can view current
product details.
version: '2.4'
x-method: searched
x-source: https://developer.barclays.com/api/apis/versions/436bee89-6e7e-4f54-9cd9-e9dc6cb90d8f.bdn/design?specification=oas31
x-harvested: '2026-09-04'
x-harvested-note: Verbatim OpenAPI 3.1 design export from the Barclays API Exchange registry (developer.barclays.com), fetched
anonymously. The untouched export is in openapi/_original/barclays-product-details-openapi.json. The UK Open Banking documents
carry OBIE (openbanking.org.uk) in info.contact/termsOfService because they are the OBIE standard contract as Barclays implements
and publishes it — the API, the registry record and the host are Barclays'.
