eWAY

eWAY (Eway) is an Australian online payment gateway founded in Sydney in 1998 and now part of Global Payments Oceania, providing card-not-present payment acceptance for e-commerce merchants across Australia, New Zealand, and Asia. Its flagship developer surface is the Rapid API, a versioned HTTP payments API (currently version 47) that processes purchases, pre-authorisations, MOTO and recurring transactions, and tokenised (stored-card) payments, offered through seven integration methods ranging from server-to-server Direct Connection to PCI-scope-reducing Transparent Redirect, Secure Fields, and the Responsive Shared Page. Merchants authenticate with an API key and password over HTTP Basic auth, and eWAY publishes open-source MIT-licensed SDKs for PHP, Java, .NET, Node.js, Ruby, Android, and iOS plus a free sandbox. The Rapid API is genuinely API-first and well documented, but eWAY does not publish a downloadable OpenAPI/Swagger definition, and no public OAuth, webhooks catalog, or AsyncAPI event stream is documented.

eWAY publishes 1 API on the APIs.io network. Tagged areas include Payments, Australia, Payment Gateway, Payment Processing, and Card Payments.

eWAY’s developer surface includes documentation, API reference, pricing, engineering blog, support, signup flow, authentication, and 23 more developer resources.

  description: The eWAY Rapid API is a versioned HTTP payments API (v47) for processing card transactions. It exposes transaction
    creation (Direct Connection), AccessCode-based flows (Transparent Redirect / Responsive Shared Page / Secure Fields),
    transaction query by ID, and token-customer, refund, and cancel-authorisation operations. Supports REST/JSON (recommended),
    plus SOAP, XML, and RPC formats. Authentication is HTTP Basic (API key as username, password as password) with an X-EWAY-APIVERSION
    header.
