OpenFin8:UK - UK Open Banking
UK open banking: the Open Banking Limited (OBL) Read/Write API ASPSP surface (v3.1.x, v4.0.1 configurable) - serving Account Information Service Providers, Payment Initiation Service Providers, and Card-Based Payment Instrument Issuers.
Summary
OpenFin8:UK is in design (OBARCH-5): the first adapter with a
non-FDX wire. The design covers the FAPI 1 Advanced ceremony
(client-credentials intent staging, hybrid flow with request
objects), intent-based consents over the kernel's
awaiting_authorization state, the {Data, Links, Meta} response
envelope, detached JWS request/response signing, OB Directory trust,
domestic payments including variable recurring payments (VRP), and
the OBL event-notification API.
UK specifications are MIT Open Licensed - unlike the FDX adapters, this one may publish the OB resource paths with the OBL notice preserved.
