Shawbrook Account & Transaction Information API (AIS, OBIE Standard, Unverified)
UK Open Banking Read/Write Account & Transaction Information API (AISP) as defined by the OBIE Account and Transaction API Specification v4.0.1 (OpenAPI 3.0.0). FAPI-secured — OAuth2/OIDC authorization, mutual-TLS client authentication, and PSD2 strong customer authentication — requiring developer onboarding with OBIE/eIDAS certificates. No Shawbrook-specific ASPSP host or developer portal could be confirmed; the harvested spec is the shared OBIE standard a UK ASPSP conforms to, not a verified Shawbrook contract.
