description: Cashflows is a United Kingdom payment gateway and card acquirer, headquartered in London and a principal member
  of Visa and Mastercard, that helps businesses accept, process, and manage card payments across online, in-app, and in-person
  channels. Its product family spans a REST Cashflows Gateway (payment jobs, captures, refunds, tokenisation, recurring payments,
  and webhooks), hosted and embedded checkout, a cardholder-not-present Payments API with 3-D Secure, a Remote Authentication
  API for connecting to the acquiring network, and an In-Person Payments API served locally from Kinetic PCI-PTS terminals.
  Cashflows ships a genuine self-serve developer portal at developer.cashflows.com with reference documentation, a dedicated
  integration/sandbox environment, and webhook-based payment notifications, but it does not publish a downloadable OpenAPI/Swagger
  definition or a public Postman collection; its API reference is hand-authored HTML. Authentication is header-based (ConfigurationId
  plus a SHA-512 request hash for the Gateway, and auth_id/auth_pass for Remote Authentication) rather than OAuth.
