Hampden & Co Confirmation of Funds API
OBIE Read/Write Confirmation of Funds Service (CBPII) allowing an authorised card-based payment instrument issuer to confirm the availability of funds, as a FAPI-secured PSD2 dedicated interface. The harvested OpenAPI is the shared OBIE Read/Write standard (v4.0.1), not a Hampden-proprietary contract; production access requires TPP onboarding with eIDAS/OBIE certificates.
