Paragon Bank Payment Initiation API (OBIE standard, unverified)
The OBIE Read/Write Payment Initiation (PIS) API standard - FAPI-secured initiation of domestic, scheduled, standing-order, international, and file payments on behalf of a customer with PSD2 strong customer authentication. Captured here as the shared OBIE standard specification, not a Paragon-hosted contract; no Paragon PIS endpoint was confirmed and Paragon does not document payment-initiation services.
