Chase UK Payment Initiation API (PIS)

Chase UK's Payment Initiation Service (PIS) dedicated interface, conformant to the OBIE Read/Write API Standard, enabling FCA-authorised PISPs to create single immediate payments, future-dated payments, and standing orders to UK accounts on behalf of a consenting customer. Access is gated behind developer onboarding and secured with FAPI OAuth2/OIDC, PSD2 SCA, and mutual-TLS. The referenced OpenAPI is the shared OBIE standard specification (v4.0.1), not a Chase-proprietary contract.
