Ozow Transactions API

openapi: 3.0.3
info:
  title: Ozow Banks Transactions API
  description: Ozow (formerly i-Pay) is a South African instant EFT / "Pay by Bank" payment gateway. Merchants create a payment request server-side, redirect the customer to the Ozow secure bank-selection flow, and receive a server-to-server notification plus browser redirect on completion. All write requests are authenticated with an ApiKey header and a SHA512 HashCheck computed by concatenating the request fields in documented order, appending the merchant PrivateKey, lower-casing, and hashing. Transactions are ZAR-only (CountryCode ZA, CurrencyCode ZAR).
