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.

scored 2026-09-08 · rubric v0.20.0
Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/eway: open an issue to ask a question, or submit a pull request to add artifacts.
